Remarks

This column hosts TextBlock elements for cells that are not in editing mode and a TextBox control for a cell that is in editing mode.

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. If a property does not have a String or numeric value type, the generated text box columns are read-only and display the data object's ToString value.

Examples

The following code example demonstrates how to specify and configure a DataGridTextColumn 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>
