Methods

	Name	Description
	CancelCellEdit	Causes the column cell being edited to revert to the specified value. (Overrides DataGridColumn.CancelCellEdit(FrameworkElement, Object).)
	CheckAccess	Determines whether the calling thread has access to this object. (Inherited from DependencyObject.)
	ClearValue	Clears the local value of a dependency property. (Inherited from DependencyObject.)
	Equals(Object)	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
	GenerateEditingElement	Gets a CheckBox control that is bound to the column's Binding property value. (Overrides DataGridColumn.GenerateEditingElement(DataGridCell, Object).)
	GenerateElement	Gets a read-only CheckBox control that is bound to the column's Binding property value. (Overrides DataGridColumn.GenerateElement(DataGridCell, Object).)
	GetAnimationBaseValue	Returns any base value established for a Silverlight dependency property, which would apply in cases where an animation is not active. (Inherited from DependencyObject.)
	GetCellContent(DataGridRow)	Gets the Content property value for the cell at the intersection of this column and the specified row. (Inherited from DataGridColumn.)
	GetCellContent(Object)	Gets the Content property value for the cell at the intersection of this column and the row that represents the specified data item. (Inherited from DataGridColumn.)
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	GetValue	Returns the current effective value of a dependency property from a DependencyObject. (Inherited from DependencyObject.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)

Remarks

By default, the DataGrid control generates columns automatically when you set the ItemsSource property. The generated columns are of type DataGridCheckBoxColumn for bound Boolean (and nullable Boolean) properties, and of type DataGridTextColumn for all other properties.

Examples

The following code example demonstrates how to specify and configure a DataGridCheckBoxColumn in XAML. This example is part of a larger example available in the DataGrid class overview.

<sdk:DataGrid x:Name="dataGrid4" 
    Height="160" Margin="0,5,0,10" 
    RowHeight="40" AutoGenerateColumns="False" >    
    <sdk:DataGrid.Columns>
        <sdk:DataGridTextColumn 
            Header="First Name" 
            Width="SizeToHeader"
            Binding="{Binding FirstName}" 
            FontSize="20" />
        <sdk:DataGridTextColumn 
            Header="Last Name" 
            Width="SizeToCells"
            Binding="{Binding LastName}" 
            FontSize="20" />
        <sdk:DataGridTextColumn 
            Header="Address"
            Width="150"
            Binding="{Binding Address}" >
            <sdk:DataGridTextColumn.ElementStyle>
                <Style TargetType="TextBlock">
                    <Setter Property="TextWrapping" Value="Wrap"/>
                </Style>
            </sdk:DataGridTextColumn.ElementStyle>
            <sdk:DataGridTextColumn.EditingElementStyle>
                <Style TargetType="TextBox">
                    <Setter Property="Foreground" Value="Blue"/>
                </Style>
            </sdk:DataGridTextColumn.EditingElementStyle>
        </sdk:DataGridTextColumn>
        <sdk:DataGridCheckBoxColumn 
            Header="New?" 
            Width="40"
            Binding="{Binding IsNew}" />
        <sdk:DataGridCheckBoxColumn 
            Header="Subscribed?" 
            Width="Auto"
            Binding="{Binding IsSubscribed}" 
            IsThreeState="True" />
    </sdk:DataGrid.Columns>
</sdk:DataGrid>
