GridCheckBoxSelectorColumn

GridCellCheckBoxSelectorRenderer

Selects or deselects rows based on the check box value, which is not bound with data object.

GridColumn

GridColumn is an abstract class provides base functionalities for all the column types in SfDataGrid.

Mapping column to particular property

Column can be bound to a property in data object using GridColumn.MappingName property. In addition, it supports to format or bind different property for display and edit mode separately via GridColumn.DisplayBinding and GridColumn.ValueBinding.

When you set MappingName, DisplayBinding and ValueBinding are created based on MappingName, if these properties are not defined explicitly. You can use DisplayBinding property to format the column in display, by setting Converter property of Binding.

public class DisplayBindingConverter : IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, string language)
    {
        return string.Format("{0:C2}", value);
    }

    public object ConvertBack(object value, Type targetType, object parameter, string language)
    {
        return value;
    }
}
xmlns:dataGrid="using:Syncfusion.UI.Xaml.DataGrid"

<dataGrid:SfDataGrid x:Name="dataGrid"
                       AllowEditing="True"
                       AutoGenerateColumns="False"
                       ItemsSource="{Binding Orders}"
                       ColumnWidthMode="SizeToHeader">
    <dataGrid:SfDataGrid.Columns>
        <dataGrid:GridTextColumn  MappingName="OrderID" HeaderText="Order ID" />
        <dataGrid:GridTextColumn  MappingName="CustomerID" HeaderText="Customer ID"/>
        <dataGrid:GridTextColumn  MappingName="ShipCity" HeaderText="Ship City"/>
        <dataGrid:GridTextColumn  MappingName="Country"/>
        <dataGrid:GridTextColumn DisplayBinding="{Binding Path=UnitPrice,
                                            Converter={StaticResource converter}}"
                   HeaderText="Unit Price"
                   MappingName="UnitPrice"
                   ValueBinding="{Binding Path=UnitPrice}" />
        <dataGrid:GridTextColumn MappingName="Quantity" />
    </dataGrid:SfDataGrid.Columns>
</dataGrid:SfDataGrid>

In the below screenshot, Unit Price column display value is formatted to currency by setting DisplayBinding property.

WinUI DataGrid Column with Currency Values

By default, Columns handling the data operations (sorting and grouping) based on MappingName property. You can perform data operations based on ValueBinding by setting GridColumn.UseBindingValue to true, when the standard reflection not works or binding column with complex or indexer properties.

CellTemplate in GridColumn

You can load any WinUI control in the display mode for all columns by setting GridColumn.CellTemplate property. In edit mode, corresponding editor will be loaded based on column type.

In the below code snippet, GridTextColumn is loaded with ProgressBar and TextBlock. When you start editing DoubleTextBox will be loaded as Editor.

<dataGrid:SfDataGrid x:Name="dataGrid"
                       AllowEditing="True"
                       AutoGenerateColumns="False"
                       ItemsSource="{Binding Orders}"
                       ColumnWidthMode="SizeToHeader">
    <dataGrid:SfDataGrid.Columns>
        <dataGrid:GridTextColumn  MappingName="OrderID" HeaderText="Order ID" />
        <dataGrid:GridTextColumn  MappingName="CustomerID" HeaderText="Customer ID"/>
        <dataGrid:GridTextColumn  MappingName="ShipCity" HeaderText="Ship City"/>
        <dataGrid:GridTextColumn  MappingName="Country"/>
        <dataGrid:GridTextColumn HeaderText="Unit Price" MappingName="UnitPrice" >
            <dataGrid:GridTextColumn.CellTemplate>
            <DataTemplate>
                <Grid>
                    <ProgressBar x:Name="progressBar"
                             Height="50"
                             Background="Transparent"
                             BorderThickness="0"
                             Maximum="50"
                             Minimum="0"
                             Visibility="Visible"
                             Value="{Binding Path=UnitPrice}" />
                    <TextBlock HorizontalAlignment="Right"
                           VerticalAlignment="Center"
                           Text="{Binding Path=UnitPrice}"
                           TextAlignment="Center" />
                </Grid>
            </DataTemplate>
            </dataGrid:GridTextColumn.CellTemplate>
        </dataGrid:GridTextColumn>
        <dataGrid:GridTextColumn MappingName="Quantity" />
    </dataGrid:SfDataGrid.Columns>
</dataGrid:SfDataGrid>

WinUI DataGrid Column with ProgressBar

CellTemplate is not support by GridHyperlinkColumn, GridCheckboxColumn and GridImageColumn columns.

Reusing same DataTemplate for multiple columns

By default, underlying record is DataContext for CellTemplate. So you have to define, template for each column to display values based on MappingName.

You can use the same DataTemplate for all columns to display value based on MappingName by setting GridColumn.SetCellBoundValue property to true.

<Page.Resources>
    <DataTemplate x:Key="cellTemplate">
        <TextBlock Margin="3,0,0,0"
                   Foreground="Red"
                   Text="{Binding Path=Value}" />
    </DataTemplate>
</Page.Resources>

<dataGrid:SfDataGrid x:Name="dataGrid"
                       AllowEditing="True"
                       AutoGenerateColumns="False"
                       ItemsSource="{Binding Orders}"
                       ColumnWidthMode="SizeToHeader">
    <dataGrid:SfDataGrid.Columns>
        <dataGrid:GridTextColumn  MappingName="OrderID" HeaderText="Order ID" CellTemplate="{StaticResource cellTemplate}" SetCellBoundValue="True" />
        <dataGrid:GridTextColumn  MappingName="CustomerID" HeaderText="Customer ID"/>
        <dataGrid:GridTextColumn  MappingName="ShipCity" HeaderText="Ship City"/>
        <dataGrid:GridTextColumn  MappingName="Country" CellTemplate="{StaticResource cellTemplate}" SetCellBoundValue="True" />
        <dataGrid:GridTextColumn HeaderText="Unit Price" MappingName="UnitPrice" />
        <dataGrid:GridTextColumn MappingName="Quantity" />
    </dataGrid:SfDataGrid.Columns>
</dataGrid:SfDataGrid>

WinUI DataGrid Column with Cell Template

Setting CellTemplate based on custom logic using TemplateSelector

GridColumn provides support to choose different DataTemplate based on underlying data object using GridColumn.CellTemplateSelector property.

For example, two different templates loaded alternatively in OrderID column.

<Application.Resources>
    <local:CustomCellTemplateSelector x:Key="cellTemplateSelector"/>
    <DataTemplate x:Key="DefaultTemplate">
        <TextBlock Foreground="Red"
                Text="{Binding Path=OrderID}"
                TextAlignment="Center" />
    </DataTemplate>
    <DataTemplate x:Key="AlternateTemplate">
        <TextBlock Foreground="Green"
                Text="{Binding Path=OrderID}"
                TextAlignment="Center" />
    </DataTemplate>
</Application.Resources>

Below code returns the DefaultTemplate and AlternateTemplate based on OrderID’s value.

public class CustomCellTemplateSelector : DataTemplateSelector
{

    protected override DataTemplate SelectTemplateCore(object item, DependencyObject container)
    {

        if (item == null)
            return null;
        var data = item as OrderInfo;

        if (data.OrderID % 2 == 0)
            return Application.Current.Resources["AlternateTemplate"] as DataTemplate;

        else
            return Application.Current.Resources["DefaultTemplate"] as DataTemplate;
    }
}

In the below code, the custom template selector set to GridColumn.CellTemplateSelector and set SetCellBoundValue to true.

<dataGrid:SfDataGrid  x:Name="dataGrid"
                        AutoGenerateColumns="False"
                        ItemsSource="{Binding Orders}">
    <dataGrid:SfDataGrid.Columns>
        <dataGrid:GridTextColumn CellTemplateSelector="{StaticResource cellTemplateSelector}"
                                   HeaderText="Order ID"
                                   MappingName="OrderID" />
    </dataGrid:SfDataGrid.Columns>
</dataGrid:SfDataGrid>

NOTE

Non-Editable columns does not support CellTemplate.

Data Formatting

GridColumn supports to format the data using Converter properties, by defining GridColumn.DisplayBinding and GridColumn.ValueBinding. GridColumn.DisplayBinding formats the data in display mode. GridColumn.ValueBinding formats the data in edit mode.

Format column using Converter

You can format the column using Converter property by defining DisplayBinding.

public class CurrencyFormatConverter : IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, string language)
    {
        return string.Format("{0:C2}", value);
    }

    public object ConvertBack(object value, Type targetType, object parameter, string language)
    {
        return value;
    }
}
<Page.Resources>
    <local:CurrencyFormatConverter x:Key="currencyFormatConverter" />
</Page.Resources>

<dataGrid:SfDataGrid x:Name="sfDataGrid"
                     AllowEditing="True"
                     ItemsSource="{Binding Orders}"
                     AutoGenerateColumns="False">
    <dataGrid:SfDataGrid.Columns>
        <dataGrid:GridTextColumn  MappingName="OrderID" HeaderText="Order ID" />
        <dataGrid:GridTextColumn  MappingName="CustomerID" HeaderText="Customer ID" />
        <dataGrid:GridTextColumn  MappingName="CustomerName" HeaderText="Customer Name" />
        <dataGrid:GridTextColumn  MappingName="ShipCity" HeaderText="Ship City" />
        <dataGrid:GridTextColumn  MappingName="Country"/>
        <dataGrid:GridTextColumn DisplayBinding="{Binding UnitPrice,
                                                           Converter={StaticResource currencyFormatConverter}}"
                                  HeaderText="Unit Price"
                                  MappingName="UnitPrice" />
    </dataGrid:SfDataGrid.Columns>
</dataGrid:SfDataGrid>

When column is auto-generated, you can set the Converter by handling AutoGeneratingColumn event.

this.sfDataGrid.AutoGeneratingColumn += SfDataGrid_AutoGeneratingColumn;

private void sfDataGrid_AutoGeneratingColumn(object sender, AutoGeneratingColumnArgs e)
{
    if (e.Column.MappingName == "UnitPrice")
    {

        if (e.Column is GridTextColumn)
        {
            e.Column = new GridTextColumn() { MappingName = "UnitPrice", HeaderText = "Unit Price" };
        }
        e.Column.DisplayBinding = new Binding() { Path = new PropertyPath(e.Column.MappingName), Converter = new CurrencyFormatConverter() };
    }
}

Styling GridColumn

GridColumn support to customize the style of particular column using GridColumn.CellStyle property.

Change the font setting

You can change the font settings such as FontSize, FontFamily, FontWeight etc. by writing style of TargetType GridCell or GridColumn.CellStyle property.

<dataGrid:SfDataGrid x:Name="dataGrid"                                                                       
                       AutoGenerateColumns="False" 
                       ItemsSource="{Binding Orders}">
    <dataGrid:SfDataGrid.Columns>
        <dataGrid:GridTextColumn MappingName="CustomerName">
            <dataGrid:GridTextColumn.CellStyle>
                <Style TargetType="dataGrid:GridCell">
                    <Setter Property="FontSize" Value="12" />
                    <Setter Property="FontFamily" Value="Segoe UI" />
                    <Setter Property="FontWeight" Value="Bold" />
                    <Setter Property="FontStyle" Value="Italic" />
                    <Setter Property="FontStretch" Value="Condensed" />
                </Style>
            </dataGrid:GridTextColumn.CellStyle>
        </dataGrid:GridTextColumn>
    </dataGrid:SfDataGrid.Columns>
</dataGrid:SfDataGrid>

When column is auto-generated, you can style the column by handling AutoGeneratingColumn event.

<Page.Resources>
    <Style x:Key="cellStyle" TargetType="dataGrid:GridCell">
        <Setter Property="FontSize" Value="12" />
        <Setter Property="FontFamily" Value="Segoe UI" />
        <Setter Property="FontWeight" Value="Bold" />
        <Setter Property="FontStyle" Value="Italic" />
        <Setter Property="FontStretch" Value="Condensed" />
    </Style>
        
</Page.Resources>
this.dataGrid.AutoGeneratingColumn += DataGrid_AutoGeneratingColumn;

private void DataGrid_AutoGeneratingColumn(object sender, Syncfusion.UI.Xaml.Grid.AutoGeneratingColumnArgs e)
{  

    if (e.Column.MappingName == "CustomerName")
        e.Column.CellStyle = this.Resources["cellStyle"] as Style;               
}

WinUI DataGrid with Customized Column Style

Styles based on custom logic

You can apply the styles to columns based on certain condition using GridColumn.CellStyleSelector property.

Below code creates two different styles by TargetType GridCell.

<Application.Resources>
    <Style x:Key="cellStyle1" TargetType="dataGrid:GridCell">
        <Setter Property="Background" Value="Bisque" />
    </Style>
    
    <Style x:Key="cellStyle2" TargetType="dataGrid:GridCell">
        <Setter Property="Background" Value="Aqua" />
    </Style>
    
</Application.Resources>

In the below code, returns the style based on OrderID value. Using Container you can format the columns data based on GridCell.

public class CustomCellStyleSelector: StyleSelector
{

    protected override Style SelectStyleCore(object item, DependencyObject container)
    {
        var gridCell = container as GridCell;
        var mappingName = gridCell.ColumnBase.GridColumn.MappingName;
        var record = gridCell.DataContext;
        var cellValue = record.GetType().GetProperty(mappingName).GetValue(record);

        if (mappingName.Equals("OrderID"))
        {

            if (Convert.ToInt16(cellValue) <= 1005)
                return App.Current.Resources["cellStyle1"] as Style;

            else
                return App.Current.Resources["cellStyle2"] as Style;
        }
        return base.SelectStyleCore(item, container);
    }
}

Below code, sets the customized style selector to GridColumn.CellStyleSelector property.

<Page.Resources>
    <local:CustomCellStyleSelector x:Key="cellStyleSelector"/>
</Page.Resources>

<dataGrid:SfDataGrid x:Name="dataGrid"
                       ItemsSource="{Binding Orders}"  
                       AutoGenerateColumns="False" >
    <dataGrid:SfDataGrid.Columns>
        <dataGrid:GridTextColumn MappingName="OrderID" CellStyleSelector="{StaticResource cellStyleSelector}">
    </dataGrid:SfDataGrid.Columns>
</dataGrid:SfDataGrid>

When column is auto-generated, you can style the column by handling AutoGeneratingColumn event.

this.dataGrid.AutoGeneratingColumn += DataGrid_AutoGeneratingColumn;

private void DataGrid_AutoGeneratingColumn(object sender, Syncfusion.UI.Xaml.Grid.AutoGeneratingColumnArgs e)
{

    if (e.Column.MappingName == "OrderID")
    {
        e.Column.CellStyleSelector = new CustomCellStyleSelector();
    }
}

WinUI DataGrid Column with Conditional Formatting

End-user Interaction

Hide Column

You can hide or unhide the particular column programmatically by setting GridColumn.IsHidden property. For allowing end-user to hide or unhide column in UI refer Resizing Columns section.

Disable column

You can disable column by setting GridColumn.AllowFocus property. Therefore, that column can’t be selected or edited.

Width, alignment and padding settings

Width

The width of GridColumn can be changed by setting Width property. Column width set based on GridColumn.MinimumWidth and GridColumn.MaximumWidth properties.

NOTE

If the GridColumn.Width is defined explicitly takes priority than GridColumn.ColumnSizer.

Padding

GridColumn allows you to the change the padding of cell content by setting Padding property.

Alignment

GridColumn allows you to change the alignment of GridCell and GridHeaderCellControl content using TextAlignment, VerticalAlignment and HorizontalHeaderContentAlignment properties.

GridTextColumnBase

GridTextColumnBase is the abstract class derived from GridColumn. The following columns are derived from the GridTextColumnBase.

  1. GridTextColumn

  2. GridNumericColumn

  3. GridDateColumn

  4. GridTimeColumn

  5. GridTemplateColumn

GridTextColumnBase properties

  • Text trimming - You can trim the column’s data using TextTrimming property.
  • Text wrapping - You can wrap the column’s data using TextWrapping property.
<dataGrid:SfDataGrid x:Name="dataGrid"
                       AutoGenerateColumns="False"
                       ItemsSource="{Binding Orders}">
    <dataGrid:SfDataGrid.Columns>
        <dataGrid:GridTextColumn Width="60"
                                   HeaderText="Customer Name"
                                   MappingName="CustomerName"
                                   TextTrimming="CharacterEllipsis"
                                   TextWrapping="Wrap" />
    </dataGrid:SfDataGrid.Columns>
</dataGrid:SfDataGrid>

WinUI DataGrid Column with Text Trimming and Text Wrapping Settings

GridTextColumn

GridTextColumn derived from GridTextColumnBase which hosts TextBox in edit mode.

<dataGrid:SfDataGrid x:Name="dataGrid"
                       AutoGenerateColumns="False"
                       ItemsSource="{Binding Orders}">
    <dataGrid:SfDataGrid.Columns>
        <dataGrid:GridTextColumn HeaderText="Customer Name" MappingName="CustomerName" />
    </dataGrid:SfDataGrid.Columns>
</dataGrid:SfDataGrid>
this.dataGrid.Columns.Add(new GridTextColumn()
{
    HeaderText = "Customer Name",
    MappingName = "CustomerName",                               
});

Spell check while editing

You can enable spell check in GridTextColumn using IsSpellCheckEnabled property.

<dataGrid:GridTextColumn HeaderText="Ship City"
                           IsSpellCheckEnabled="True"
                           MappingName="ShipCity" />
this.dataGrid.Columns.Add(new GridTextColumn() { HeaderText = "Ship City", MappingName = "ShipCity", IsSpellCheckEnabled = true });

GridNumericColumn

GridNumericColumn is derived from GridTextColumnBase and hosts the NumberBox in edit mode.

<dataGrid:SfDataGrid x:Name="dataGrid" 
                       ItemsSource="{Binding Orders}"
                       AutoGenerateColumns="False" 
                       AllowEditing="True" >
    <dataGrid:SfDataGrid.Columns>
        <dataGrid:GridTextColumn MappingName="CustomerID" HeaderText="Customer ID" />

        <dataGrid:GridTextColumn MappingName="ShipCity" HeaderText="Ship City" />
    </dataGrid:SfDataGrid.Columns>
</dataGrid:SfDataGrid>
this.dataGrid.Columns.Add(new GridNumericColumn()
{
    HeaderText = "Unit Price",
    MappingName = "UnitPrice",                               
});

WinUI DataGrid Column with NumericColumn

Change the format of numeric value

You can format the value of a GridNumericColumn using the DisplayNumberFormat or NumberFormatter property. The default value of DisplayNumberFormat and NumberFormatter properties are null.

The following example shows how to set PercentFormatter for NumberFormatter property.

NOTE

To learn more about the formatting classes that can be assigned to the NumberFormatter property.
Refer here

// Format numericColumn in percent
numericColumn.NumberFormatter = new PercentFormatter();

You can also set CurrencyFormatter and DecimalFormatter for NumberFormatter property to format the values in currency and numeric custom formats.

Using the N, C, and P format values, you can apply numeric, currency, and percent custom formats in DisplayNumberFormat property.

NOTE

When using both the DisplayNumberFormat and the NumberFormatter properties, the DisplayNumberFormat property takes high precedence.

<dataGrid:SfDataGrid x:Name="dataGrid"                                                                       
                       AutoGenerateColumns="False" 
                       ItemsSource="{Binding Orders}"
                       AllowEditing="True" >
    <dataGrid:SfDataGrid.Columns>
        <dataGrid:GridTextColumn MappingName="CustomerID" HeaderText="Customer ID" />
        <dataGrid:GridTextColumn MappingName="CustomerName" HeaderText="Customer Name" />
        <dataGrid:GridNumericColumn x:Name="numericColumn" HeaderText="Discount" MappingName="Discount" DisplayNumberFormat="P2" />
        <dataGrid:GridTextColumn MappingName="Country" />
        <dataGrid:GridTextColumn MappingName="ShipCity" HeaderText="Ship City" />
    </dataGrid:SfDataGrid.Columns>
</dataGrid:SfDataGrid>
// Format numericColumn in percent
numericColumn.DisplayNumberFormat = "P2";

WinUI DataGrid Column with NumericColumn in Percent Format

Null value support

GridNumericColumn provides support to restrict or allow null value in columns based on AllowNull property. Instead of displaying null values, you can display hint text using the PlaceholderText property.

The PlaceholderText is not displayed, when the AllowNull is set to false.

<dataGrid:SfDataGrid x:Name="dataGrid"

        <dataGrid:GridCheckBoxColumn HeaderText="Is Delivered" MappingName="IsDelivered" />
    </dataGrid:SfDataGrid.Columns>
</dataGrid:SfDataGrid>
this.dataGrid.Columns.Add(new GridCheckBoxColumn() { HeaderText = "Is Delivered", MappingName = "IsDelivered" });

WinUI DataGrid Column with CheckBox

GridCheckBoxColumn allows you to customize check box state and its alignment.

  • IsThreeState - By default, the GridCheckBoxColumn has Checked and Unchecked state. You can enable another Intermediate state setting IsThreeState property to true.

  • HorizontalAlignment - You can change the horizontal alignment of CheckBox using HorizontalAlignment property.

GridTemplateColumn

GridTemplateColumn derived from GridTextColumnBase and it displays the template-specified cell content. You can load any WinUI control in the display mode for all columns by setting CellTemplate and EditTemplate properties.

<dataGrid:SfDataGrid x:Name="dataGrid"                                                                       
                       AutoGenerateColumns="False" 
                       ItemsSource="{Binding Orders}">
    <dataGrid:SfDataGrid.Columns>
        <dataGrid:GridTemplateColumn MappingName="CustomerID">           
            <dataGrid:GridTemplateColumn.CellTemplate>
                <DataTemplate>
                    <TextBlock Text="{Binding CustomerID}" />
                </DataTemplate>
            </dataGrid:GridTemplateColumn.CellTemplate>
            <dataGrid:GridTemplateColumn.EditTemplate>
                <DataTemplate>
                    <TextBox Text="{Binding CustomerID, Mode=TwoWay}" />
                </DataTemplate>
            </dataGrid:GridTemplateColumn.EditTemplate>        
            </dataGrid:GridTemplateColumn>       
    </dataGrid:SfDataGrid.Columns>
</dataGrid:SfDataGrid>
StringBuilder sb1 = new StringBuilder();
sb1.Append("<DataTemplate xmlns=\"http://schemas.microsoft.com/winfx/2006/xaml/presentation\">");          
sb1.Append("<TextBlock Text=\"{Binding CustomerID}\" />");                       
sb1.Append("</DataTemplate>");
DataTemplate cellTemplate = (DataTemplate)XamlReader.Load(sb1.ToString());

StringBuilder sb2 = new StringBuilder();
sb2.Append("<DataTemplate xmlns=\"http://schemas.microsoft.com/winfx/2006/xaml/presentation\">");
sb2.Append("<TextBox Text=\"{Binding CustomerID, Mode=TwoWay}\" />");
sb2.Append("</DataTemplate>");
DataTemplate editTemplate = (DataTemplate)XamlReader.Load(sb2.ToString());

this.dataGrid.Columns.Add(new GridTemplateColumn() { MappingName = "IsClosed", CellTemplate = cellTemplate, EditTemplate = editTemplate });

Binding CellTemplate and EditTemplate based on MappingName

By default, underlying record is DataContext for CellTemplate. So you have to define, template for each column to display values based on MappingName.

You can use the same DataTemplate for all columns to display value based on MappingName by setting SetCellBoundValue property to true.

NOTE

EditTemplate support available only for GridTemplateColumn.

<dataGrid:SfDataGrid x:Name="dataGrid"                                                                       
                       AutoGenerateColumns="False" 
                       ItemsSource="{Binding Orders}">
    <dataGrid:SfDataGrid.Columns>
        <dataGrid:GridTemplateColumn MappingName="OrderID" SetCellBoundValue="True">
            <dataGrid:GridTemplateColumn.CellTemplate>
                <DataTemplate>
                    <Grid>
                        <TextBlock Text="{Binding Value}" />
                    </Grid>
                </DataTemplate>
            </dataGrid:GridTemplateColumn.CellTemplate>
            <dataGrid:GridTemplateColumn.EditTemplate>
                <DataTemplate>
                    <Grid>
                        <TextBox Text="{Binding Value}" />
                    </Grid>
                </DataTemplate>
            </dataGrid:GridTemplateColumn.EditTemplate>
        </dataGrid:GridTemplateColumn>
    </dataGrid:SfDataGrid.Columns>
</dataGrid:SfDataGrid>

Sets EditTemplate based on custom logic

GridTemplateColumn provides support to load different edit elements based on underlying data object using GridTemplateColumn.EditTemplateSelector property.

Below code returns the DefaultTemplate and AlternateTemplate based on OrderID’s value.

<DataTemplate x:Key="DefaultCellTemplate">
    <TextBlock VerticalAlignment="Center"
               Foreground="Red"
               Text="{Binding Path=OrderID}"
               TextAlignment="Center" />
</DataTemplate>

<DataTemplate x:Key="AlternateCellTemplate">
    <TextBlock VerticalAlignment="Center"
               Foreground="Green"
               Text="{Binding Path=OrderID}"
               TextAlignment="Center" />
</DataTemplate>

<DataTemplate x:Key="DefaultEditTemplate">
    <TextBox Height="45"
             VerticalAlignment="Center"
             Foreground="Red"
             Text="{Binding Path=OrderID}"
             TextAlignment="Center" />
</DataTemplate>

<DataTemplate x:Key="AlternateEditTemplate">
    <TextBox Height="45"
             VerticalAlignment="Center"
             Foreground="Green"
             Text="{Binding Path=OrderID}"
             TextAlignment="Center" />
</DataTemplate>
public class CustomEditTemplateSelector: DataTemplateSelector
{
 
    protected override DataTemplate SelectTemplateCore(object item, DependencyObject container)
    {
 
        if (item == null)
            return null;

        var data = item as OrderInfo;
 
        if (data.OrderID % 2 == 0)
            return Appliaction.Current.Resources["AlternateEditTemplate"] as DataTemplate;
 
        else
            return Application.Current.Resources["DefaultEditTemplate"] as DataTemplate;
    }
}

In the below code, custom template selector set to GridTemplateColumn.EditTemplateSelector.

GridComboBoxColumn

GridComboBoxColumn derived from GridColumn which hosts ComboBox as edit element. The data source to ComboBox can be set by using GridComboBoxColumn.ItemsSource property.

By default, GridComboBoxColumn displays the value using MappingName property. You can set DisplayMemberPath which denotes the path to a value on the source object (GridComboBoxColumn.ItemsSource) to serve as the visual representation of object. You can set the SelectedValuePath which denotes the path to get the SelectedValue from the SelectedItem.

<dataGrid:SfDataGrid x:Name="dataGrid"                                                                       
                       AutoGenerateColumns="False" 
                       ItemsSource="{Binding Orders}">
                       
    <dataGrid:SfDataGrid.Columns> 
        <dataGrid:GridComboBoxColumn  HeaderText="Customer ID"
                                        ItemsSource="{Binding ComboItems, Source={StaticResource viewModel}}"
                                        MappingName=" Customer ID " />
    </dataGrid:SfDataGrid.Columns> 
</dataGrid:SfDataGrid>
this.dataGrid.Columns.Add(new GridComboBoxColumn() { HeaderText = " Customer ID ", MappingName = " Customer ID ", ItemsSource = viewModel.ComboItems });

SfDataGrid triggers, CurrentCellDropDownSelectionChanged event, when the SelectedValue is changed. CurrentCellDropDownSelectionChangedEventArgs of CurrentCellDropDownSelectionChanged event provides the information about the changed cell value.

SelectedIndex property returns the index of selected item.
SelectedItem property returns the selected item from drop down list.

        <Setter Property="ItemsPanel">
            <Setter.Value>
                <ItemsPanelTemplate>
                    <VirtualizingStackPanel />
                </ItemsPanelTemplate>
            </Setter.Value>
        </Setter>
    </Style>
</Page.Resources>

Opening dropdown popup in single-click

You can open the drop down within single click by setting ComboBox.IsDropDownOpen property to true in OnEditElementLoaded method by overriding existing renderer.

Below code, creates GridCellComboBoxRendererExt to set IsDropDownOpen property. Replace the default renderer with created renderer in SfDataGrid.CellRenderers collection.

this.dataGrid.CellRenderers.Remove("ComboBox");
this.dataGrid.CellRenderers.Add("ComboBox", new GridCellComboBoxRendererExt());

public class GridCellComboBoxRendererExt: GridCellComboBoxRenderer
{

    protected override void OnEditElementLoaded(object sender, Windows.UI.Xaml.RoutedEventArgs e)
    {
        (sender as ComboBox).IsDropDownOpen = true;
        base.OnEditElementLoaded(sender, e);
    }
}

NOTE

This is applicable when the SfDataGrid.EditTrigger is set as OnTap.

CurrentCellRequestNavigateEventArgs of CurrentCellRequestNavigate event provide information about the hyperlink triggered this event. CurrentCellRequestNavigateEventArgs.NavigateText returns the value using ValueBinding or MappingName to navigate.

this.dataGrid.CurrentCellRequestNavigate += DataGrid_CurrentCellRequestNavigate;   
                             
private void DataGrid_CurrentCellRequestNavigate(object sender, CurrentCellRequestNavigateEventArgs args)
{
    var URI = string.Format("https://en.wikipedia.org/wiki/" + args.NavigateText);
    Windows.System.Launcher.LaunchUriAsync(new Uri(URI));          
}

Cancel the navigation

You can cancel the navigation when clicking hyperlink by setting CurrentCellRequestNavigateEventArgs.Handled to false.

this.dataGrid.CurrentCellRequestNavigate += dataGrid_CurrentCellRequestNavigate;

void dataGrid_CurrentCellRequestNavigate(object sender, CurrentCellRequestNavigateEventArgs args)
{
    args.Handled = true;
}

Change the alignment

You can change the horizontal alignment of GridHyperlinkColumn using HorizontalAlignment property.

Null value support

GridTimeColumn provides support to restrict or allow null value in columns based on AllowNull property. The default value of AllowNull property is True. Instead of displaying null values, you can display hint text using the PlaceholderText property.

The PlaceholderText is not displayed, when the AllowNull is set to false. The default value of PlaceholderText property is select a time.

<dataGrid:SfDataGrid x:Name="dataGrid" 
                       ItemsSource="{Binding Orders}"
                       AutoGenerateColumns="False"

GridToggleSwitchColumn

GridToggleSwitchColumn derived from GridColumn and it is used to display Boolean type data. It hosts ToggleSwitch element as GridCell content.

<dataGrid:SfDataGrid x:Name="sfDataGrid"
                       AutoGenerateColumns="False"
                       AllowEditing="True"
                       ItemsSource="{Binding OrderInfoCollection}">
    <dataGrid:SfDataGrid.Columns>
        <dataGrid:GridToggleSwitchColumn HeaderText="IsDelivered" MappingName="IsDelivered"/>
    </dataGrid:SfDataGrid.Columns>
</dataGrid:SfDataGrid>
this.sfDataGrid.Columns.Add(new GridToggleSwitchColumn() { MappingName = "IsDelivered", HeaderText = "IsDelivered" });

ToggleSwitch Content Settings

GridCheckBoxSelectorColumn

SfDataGrid allows you to select or deselect individual rows through CheckBox using the GridCheckBoxSelectorColumn, which is not bound with data object from underlying data source, and it can be added like normal columns. The selector column supports row selection alone, and selection in selector column works based on SelectionMode.

<dataGrid:SfDataGrid x:Name="dataGrid"                                                                       
                       AutoGenerateColumns="False" 
                       ItemsSource="{Binding Orders}">
      <dataGrid:SfDataGrid.Columns>
            <dataGrid:GridCheckBoxSelectorColumn MappingName="SelectorColumn" 
                                                   Width="50"/>
      </dataGrid:SfDataGrid.Columns>
</dataGrid:SfDataGrid>
this.dataGrid.Columns.Add(new GridCheckBoxSelectorColumn() 
{ 
       MappingName = "SelectorColumn", 
       Width = 50 
});

By default, check box is displayed in header of selector column, which is used to select or deselect all the rows in the datagrid.

Text on column header

You can display text instead of check box in header of selector column by setting the AllowCheckBoxOnHeader property to False.

<dataGrid:SfDataGrid x:Name="dataGrid"                                                                       
                       AutoGenerateColumns="False" 
                       ItemsSource="{Binding Orders}">
      <dataGrid:SfDataGrid.Columns>
            <dataGrid:GridCheckBoxSelectorColumn MappingName="SelectorColumn"
                                                   AllowCheckBoxOnHeader="False"
                                                   HeaderText="Selector" 
                                                   Width="70"/>         
      </dataGrid:SfDataGrid.Columns>
</dataGrid:SfDataGrid>
this.dataGrid.Columns.Add(new GridCheckBoxSelectorColumn() 
{ 
       HeaderText = "Selector", 
       MappingName = "SelectorColumn", 
       AllowCheckBoxOnHeader = false , 
       Width = 70 
});

Styling WinUI DataGrid CheckBox Selector Column

Limitations

The following are the limitations of GridCheckBoxSelectorColumn:

  • Selector column does not support cell selection.
  • Selector column does not support data operations like sorting, filtering, and grouping.
  • Selector column will be excluded in operations like printing and exporting.
  • Selector column does not have filter row support.

Custom column support

SfDataGrid allows you to create your own column by overriding predefined column type or creating a new custom column.

Customize column renderer

SfDataGrid allows you to customize the column related operations like key navigation and UI related interactions by overriding the corresponding renderer associated with the column. Each column has its own renderer with set of virtual methods for handling the column level operations.

Below table lists the available cell types for columns and its renderers.

Column Name Renderer Cell Type
GridTextColumn

GridCellTextBoxRenderer

TextBox
GridNumericColumn

GridCellNumericRenderer

Numeric
GridDateColumn

GridCellDateRenderer

DateTimeOffset
GridCheckBoxColumn

GridCellCheckBoxRenderer

CheckBox
GridTemplateColumn

GridCellTemplateRenderer

Template
GridTimeColumn

GridCellTimeRenderer

Time
GridImageColumn

GridCellImageRenderer

GridUnBoundColumn

GridUnBoundCellTextBoxRenderer

GridUnBoundCellTemplateRenderer

GridComboBoxColumn

GridCellComboBoxRenderer

ComboBox
GridHyperlinkColumn

GridCellHyperLinkRenderer

HyperlinkButton
GridCheckBoxSelectorColumn

GridCellCheckBoxSelectorRenderer

Selector
GridToggleSwitchColumn

GridCellToggleSwitchRenderer

ToggleSwitch

Below code, creates the GridCellTextBoxRendererExt to change the foreground of CustomerID column and replacing created renderer to CellRenderers.

this.dataGrid.CellRenderers.Remove("TextBox");
this.dataGrid.CellRenderers.Add("TextBox", new GridCellTextBoxRendererExt());

public class GridCellTextBoxRendererExt: GridCellTextBoxRenderer
{

    public override void OnInitializeDisplayElement(DataColumnBase dataColumn, TextBlock uiElement, object dataContext)
    {
        base.OnInitializeDisplayElement(dataColumn, uiElement, dataContext);

        if (dataColumn.GridColumn.MappingName.Equals("CustomerID"))
            uiElement.Foreground = new SolidColorBrush(Colors.Blue);
    }

    public override void OnUpdateDisplayBinding(DataColumnBase dataColumn, TextBlock uiElement, object dataContext)
    {
        base.OnUpdateDisplayBinding(dataColumn, uiElement, dataContext);

        if (dataColumn.GridColumn.MappingName.Equals("CustomerID"))
            uiElement.Foreground = new SolidColorBrush(Colors.Blue);
    }
}

Customize the column in WinUI DataGrid

Creating new column and renderer

You can create a new column by deriving GridColumn, rendered in UI using customized CellType using GridVirtualizingCellRenderer.

Below steps to create custom column in SfDataGrid.

How To

Restrict the input content length

You can restrict the range of input using MaxLength property on GridColumn in below ways.

  • Using Converter property in DisplayBinding and ValueBinding
  • Using control style
  • Overriding existing cell types

Using Converter

You can restrict the length of user input in both display and edit element using Converter using DisplayBinding and ValueBinding.

public class MaxLengthConverter : IValueConverter
{

    public object Convert(object value, Type targetType, object parameter, string language)
    {

        // Define maxLength for column
        int maxLength = 5;

        // Get the ColumnValue
        var columnValue = System.Convert.ToString(value);

        if (columnValue.Length < maxLength)
            return columnValue;

        else
            return columnValue.Substring(0, maxLength);
    }

    public object ConvertBack(object value, Type targetType, object parameter, string language)
    {
        return value;
    }
}

    <local:MaxLengthConverter x:Key="converter" />
</Page.Resources>

<dataGrid:SfDataGrid x:Name="dataGrid"                                                                       
                       AutoGenerateColumns="False" 
                       ItemsSource="{Binding Orders}">
    <dataGrid:SfDataGrid.Columns>
        <dataGrid:GridTextColumn  DisplayBinding="{Binding CustomerName,
                                                             Converter={StaticResource converter}}"
                                    HeaderText="Customer Name"
                                    MappingName="CustomerName"
                                    ValueBinding="{Binding CustomerName,
                                                           Converter={StaticResource converter}}" />
    </dataGrid:SfDataGrid.Columns>
</dataGrid:SfDataGrid>

Using control style

You can set the MaxLength property in edit mode by writing style of TargetType edit element of the corresponding column.

NOTE

TextBlock does not have the MaxLength property. Therefore, you can use the converter to format in display.

<Page.Resources>
    <Style TargetType="TextBox">
        <Setter Property="MaxLength" Value="7" />
    </Style>
</Page.Resources>

<dataGrid:SfDataGrid x:Name="dataGrid"                                                                       
                       AutoGenerateColumns="False" 
                       ItemsSource="{Binding Orders}">
    <dataGrid:SfDataGrid.Columns>
        <dataGrid:GridTextColumn  MappingName="CustomerName"/>
    </dataGrid:SfDataGrid.Columns>
</dataGrid:SfDataGrid>

Overriding existing cell types

You can set the MaxLength property to the edit element of the particular column by overriding existing cell types.

Below code, overrides the OnInitializeEditElement method of the corresponding renderer and set the MaxLength to the UIElement and add the renderer to SfDataGrid.CellRenderers collection.

this.dataGrid.CellRenderers.Remove("TextBox");
this.dataGrid.CellRenderers.Add("TextBox", new GridCellTextBoxRendererExt());

public class GridCellTextBoxRendererExt : GridCellTextBoxRenderer
{
