Record Template View in WPF DataGrid (SfDataGrid)

The SfDataGrid provides support to represent additional information of a row using TemplateViewDefinition that can be defined in datagrid. It allows you to load any WPF controls to TemplateViewDefinition.RowTemplate in order to display the additional information of a row. You can expand or collapse the row template view by using an expander in a row or programmatically.

Defining row template

Template view can be generated for the master row by using the RowTemplate defined in the TemplateViewDefinition.

Follow the below steps to define the row template,
* Create TemplateViewDefinition.
* Define data template for the TemplateViewDefinition.RowTemplate property.
* Then add TemplateViewDefinition to the SfDataGrid.DetailsViewDefinition.

You can bind the row data using the Data.PropertyName (where Data is the underlying object bound).

Record template view with different templates for each row using RowTemplateSelector in WPF DataGrid

Height customization

Height mode

You can customize height of the row that contains RowTemplate by using the TemplateViewDefinition.HeightMode property. The height modes are as follows.

Height mode Definition
Auto Arranges template for the actual size as the

RowTemplate

is measured.
Fixed Arranges template for the specified height in

TemplateViewDefinition.Height

.
ViewPort Arranges template for the ViewPortHeight when the

RowTemplate

actual height is greater than ViewPortHeight.

Keyboard navigation support for DetailsViewTemplate

In the SfDataGrid, you can navigate from parent row to DetailsViewTemplate and vice-versa using Tab key by default. You can also restrict tab key navigation from parent to DetailsViewTemplate by setting the TemplateViewDefinition.TemplateNavigationMode property value to ExcludeTemplateRow.

<syncfusion:SfDataGrid Name="dataGrid"
                       AutoGenerateColumns="False"                                    
                       ItemsSource="{Binding OrderList}">
	<syncfusion:SfDataGrid.DetailsViewDefinition>
		<syncfusion:TemplateViewDefinition  RowTemplate="{StaticResource DetailsViewTemplate}" TemplateNavigationMode="ExcludeTemplateRow`"/>
	</syncfusion:SfDataGrid.DetailsViewDefinition>
</Syncfusion.SfDataGrid>

NOTE

Except Tab key, other keys does not allow keyboard navigation from parent row to DetailsViewTemplate and vice-versa.

Populating record template view using events

You can set the RowTemplate on-demand when expanding the record by using the GridDetailsViewExpandingEventArgs.RowTemplate property in SfDataGrid.DetailsViewExpanding event handler.

<syncfusion:SfDataGrid Name="dataGrid"
                       AutoGenerateColumns="False"                                    
                       ItemsSource="{Binding OrderList}">
	<syncfusion:SfDataGrid.DetailsViewDefinition>
		<syncfusion:TemplateViewDefinition  RowTemplate="{StaticResource DetailsViewTemplate}"/>
	</syncfusion:SfDataGrid.DetailsViewDefinition>
</Syncfusion.SfDataGrid>
private DataTemplate GetDataTemplate()
{
    FrameworkElementFactory textBlock = new FrameworkElementFactory(typeof(TextBlock));
    Binding binding = new Binding();
    textBlock.SetBinding(TextBlock.TextProperty, binding);
    binding.Path = new PropertyPath("Data.ProductName");
    var dataTemplate = new DataTemplate() { VisualTree = textBlock };
    return dataTemplate;
}

private void dataGrid_DetailsViewExpanding(object sender, Syncfusion.UI.Xaml.Grid.GridDetailsViewExpandingEventArgs e)
{
    e.RowTemplate = GetDataTemplate();
}

Expanding and collapsing row template programmatically

The SfDataGrid allows you to expand or collapse the RowTemplate programmatically in different ways.

Expand or collapse all the row template

You can expand or collapse all the RowTemplate by using the ExpandAllDetailsView and CollapseAllDetailsView methods.

this.dataGrid.ExpandAllDetailsView();
this.dataGrid.CollapseAllDetailsView();

Expand or collapse row template based on record index

You can expand or collapse the RowTemplate based on the record index by using the ExpandDetailsViewAt and CollapseDetailsViewAt methods.

this.dataGrid.ExpandDetailsViewAt(0);
this.dataGrid.CollapseDetailsViewAt(0);

Handling events

DetailsViewExpanding

The DetailsViewExpanding event is raised when the RowTemplate is expanded by using an expander.

this.dataGrid.DetailsViewExpanding += dataGrid_DetailsViewExpanding;

void dataGrid_DetailsViewExpanding(object sender, Syncfusion.UI.Xaml.Grid.GridDetailsViewExpandingEventArgs e)
{
}

DetailsViewExpanded

The DetailsViewExpanded event is raised when the RowTemplate is expanded by using an expander.

this.dataGrid.DetailsViewExpanded += dataGrid_DetailsViewExpanded;

void dataGrid_DetailsViewExpanded(object sender, Syncfusion.UI.Xaml.Grid.GridDetailsViewExpandingEventArgs e)
{
}

DetailsViewCollapsing

The DetailsViewCollapsing event is raised when the RowTemplate is collapsed by using an expander.

this.dataGrid.DetailsViewCollapsing += dataGrid_DetailsViewCollapsing;

void dataGrid_DetailsViewCollapsing(object sender, Syncfusion.UI.Xaml.Grid.GridDetailsViewExpandingEventArgs e)
{
}

DetailsViewCollapsed

The DetailsViewCollapsed event is raised when the RowTemplate is collapsed by using an expander.

this.dataGrid.DetailsViewCollapsed += dataGrid_DetailsViewCollapsed;

void dataGrid_DetailsViewCollapsed(object sender, Syncfusion.UI.Xaml.Grid.GridDetailsViewExpandingEventArgs e)
{
}

Cancel expanding or collapsing operations through events

You can cancel the expanding operation when expanding the RowTemplate by using the GridDetailsViewExpandingEventArgs.Cancel property in the DetailsViewExpanding event handler.

this.dataGrid.DetailsViewExpanding += dataGrid_DetailsViewExpanding;

void dataGrid_DetailsViewExpanding(object sender, Syncfusion.UI.Xaml.Grid.GridDetailsViewExpandingEventArgs e)
{
 
    if ((e.Record as OrderInfo).OrderID == 1002)
        e.Cancel = true;
}

Similarly, the collapsing operation can also be canceled through the GridDetailsViewCollapsingEventArgs.Cancel property in DetailsViewCollapsing event handler.

this.dataGrid.DetailsViewCollapsing += dataGrid_DetailsViewCollapsing;

void dataGrid_DetailsViewCollapsing(object sender, Syncfusion.UI.Xaml.Grid.GridDetailsViewCollapsingEventArgs e)
{
 
    if ((e.Record as OrderInfo).OrderID == 1002)
        e.Cancel = true;
}

Limitations

Limitations are:

  • Does not support both DetailsViewTemplate and DetailsViewDataGrid at same level.
  • Does not support more than one DetailsViewTemplate in same level.
