Represents a column that can be used to display non-data related information such as a label or controls that allow some sort of action to be carried out (e.g., a button to open a window in which the current item can be edited).
The following example demonstrates how to use an unbound column to display a button that, when clicked, will display an editor through which the corresponding data item can be edited.
<Grid xmlns:xcdg="http://schemas.xceed.com/wpf/xaml/datagrid">
<Grid.Resources>
<xcdg:DataGridCollectionViewSource x:Key="cvs_products"
Source="{Binding Source={x:Static Application.Current}, Path=Products}" />
</Grid.Resources>
<xcdg:DataGridControl x:Name="OrdersGrid"
ItemsSource="{Binding Source={StaticResource cvs_products}}">
<xcdg:DataGridControl.Columns>
<xcdg:UnboundColumn FieldName="EditRowColumn"
Width="30"
MinWidth="30"
MaxWidth="30">
<xcdg:UnboundColumn.CellContentTemplate>
<DataTemplate>
<Button Click="Button_Click"
Content="..." />
</DataTemplate>
</xcdg:UnboundColumn.CellContentTemplate>
</xcdg:UnboundColumn>
<xcdg:Column FieldName="Photo"
Visible="False" />
</xcdg:DataGridControl.Columns>
</xcdg:DataGridControl>
</Grid>
The following code provides the implementation of the Button_Click event. The ProductsEditorWindow derives from Window and allows the data item to be edited. The code for the ProductsEditorWindow is not provided.
Private Sub Button_Click( ByVal sender As Object, ByVal e As RoutedEventArgs )
Dim cell As Cell = Cell.FindFromChild( TryCast( sender, DependencyObject ) )
Dim editor As New ProductsEditorWindow( TryCast( DataGridControl.GetParentDataGridControl( cell ).GetItemFromContainer( cell.ParentRow ), DataRowView ) )
editor.ShowDialog()
End Sub
