Columns Resizing in MAUI DataGrid (SfDataGrid)

The SfDataGrid allows you to resize the columns by tapping and dragging the right border of the column headers. Resizing can be enabled or disabled by setting the SfDataGrid.AllowResizingColumns property. A resizing indicator is displayed while resizing a column.

NOTE

Resizing considers DataGridColumn.MinimumWidth and DataGridColumn.MaximumWidth of the column and will not exceed the minimum and maximum width constraints.

XAML

<syncfusion:SfDataGrid  x:Name="dataGrid"
                        AllowResizingColumns="True"
                        ItemsSource="{Binding Orders}" />

C#

dataGrid.AllowResizingColumns = true;

To hide a column interactively, set the DataGridColumn.MinimumWidth property to zero. Then, resize the column to a width less than zero.

Resizing events

Based on the requirements, resizing operations can be handled using the SfDataGrid.ColumnResizing event. The SfDataGrid.ColumnResizing event is triggered while resizing a column and will continue to be triggered until the resizing operation is complete.

By handling the SfDataGrid.ColumnResizing event, it is possible to cancel the resizing of a particular column.

The SfDataGrid.ColumnResizing event provides the following properties through DataGridColumnResizingEventArgs:

• Index - Returns the index of the column currently being resized.
• NewValue - Returns the current width of the column being resized.
• ResizingState - Returns the current state of the user interaction through a value from the DataGridProgressState enum.
• Cancel - A Boolean property to cancel the resizing operation.

Cancel resizing for a column

To cancel resizing a specific column, use the SfDataGrid.ColumnResizing event. Based on the various arguments provided in the DataGridColumnResizingEventArgs, the resizing operation of a column can be canceled.

To prevent resizing a column using the SfDataGrid.ColumnResizing event and the Index value, refer to the following code example:

C#

this.dataGrid.ColumnResizing += DataGrid_ColumnResizing;

private void DataGrid_ColumnResizing(object? sender, Syncfusion.Maui.DataGrid.DataGridColumnResizingEventArgs e)
{
    //Code to end resizing if ColumnIndex is 2
    if (e.Index == 2)
        e.Cancel = true;
}

To cancel resizing a column using the SfDataGrid.ColumnResizing event and the NewValue value, refer to the following code example:

C#

this.dataGrid.ColumnResizing += DataGrid_ColumnResizing;

private void DataGrid_ColumnResizing(object? sender, Syncfusion.Maui.DataGrid.DataGridColumnResizingEventArgs e)
{
    //Code to end resizing if Column's Width is >= 100
    if (e.NewValue >= 100)
        e.Cancel = true;
}

To cancel resizing a column using the SfDataGrid.ColumnResizing event and the DataGridProgressState value, refer to the code example below:

C#

this.dataGrid.ColumnResizing += DataGrid_ColumnResizing;

private void DataGrid_ColumnResizing(object? sender, Syncfusion.Maui.DataGrid.DataGridColumnResizingEventArgs e)
{
    // Code to end resizing if interaction state is Progressing
    if (e.ResizingState == Syncfusion.Maui.DataGrid.DataGridProgressState.Progressing)
        e.Cancel = true;
}

Customize the appearance

The SfDataGrid allows you to change the resizing indicator color using SfDataGrid.DefaultStyle.ColumnResizingIndicatorColor.

XAML

<syncfusion:SfDataGrid  x:Name="dataGrid"
                        AllowResizingColumns="True"
                        ItemsSource="{Binding Orders}">
            <syncfusion:SfDataGrid.DefaultStyle>
                <syncfusion:DataGridStyle ColumnResizingIndicatorColor="Blue"/>
            </syncfusion:SfDataGrid.DefaultStyle>
</syncfusion:SfDataGrid>

C#

dataGrid.AllowResizingColumns = true;
dataGrid.DefaultStyle.ColumnResizingIndicatorColor = Colors.Blue;
