DataGridColumn::IsFrozen Property

Gets a value that indicates whether the column is prevented from scrolling horizontally.

Namespace:  System.Windows.Controls
Assembly:  PresentationFramework (in PresentationFramework.dll)

public:
property bool IsFrozen {
	bool get ();
	internal: void set (bool value);
}

Property Value

Type: System::Boolean
true if the column cannot be scrolled horizontally; otherwise, false. The registered default is false. For information about what can influence the value, see DependencyProperty.

IsFrozen cannot be used to freeze a column. Instead, set the FrozenColumnCount property. The leftmost columns up to the column that is specified by the FrozenColumnCount number will freeze in place.

The following example shows how to freeze a column when "Freeze Column" is selected from the ContextMenu. Columns are moved to the left in order to be included in the frozen columns.

<!--Defines the handlers for when the FreezeColumnCommand is executed-->
<Window.CommandBindings>
    <CommandBinding Command="{x:Static local:Window1.FreezeColumnCommand}" Executed="CommandBinding_Executed" />
</Window.CommandBindings>
<!--Defines the context menu for the ColumnHeaders and attaches the FreezeColumnCommand-->
<Window.Resources>
    <ContextMenu x:Key="ColumnHeaderMenu" IsEnabled="True"  >
        <MenuItem Header="Freeze Column" IsEnabled="True" Command="{x:Static local:Window1.FreezeColumnCommand}"
                  CommandTarget="{Binding RelativeSource={RelativeSource AncestorType=Popup}, Path=PlacementTarget}" 
                  CommandParameter="{Binding ElementName=DG1, Path=CurrentColumn.DisplayIndex}" />
    </ContextMenu>
</Window.Resources>

<Grid>
    <!--Creates a new DataGrid with a context menu for the column headers-->
    <DataGrid Name="DG1" ItemsSource="{Binding}"  >
        <DataGrid.ColumnHeaderStyle >
            <Style TargetType="DataGridColumnHeader">
                <Setter Property="ContextMenu" Value="{StaticResource ColumnHeaderMenu}" />
            </Style>
        </DataGrid.ColumnHeaderStyle>
    </DataGrid>
</Grid>
