    UnboundColumn Class
    In This Topic
    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).
    Syntax
    'Declaration
 
<DebuggerDisplayAttribute("FieldName = {FieldName}")>
<TypeDescriptionProviderAttribute(MS.Internal.ComponentModel.DependencyObjectProvider)>
<NameScopePropertyAttribute("NameScope", System.Windows.NameScope)>
Public Class UnboundColumn 
   Inherits ColumnBase
    'Usage
 
Dim instance As UnboundColumn
    [DebuggerDisplay("FieldName = {FieldName}")]
[TypeDescriptionProvider(MS.Internal.ComponentModel.DependencyObjectProvider)]
[NameScopeProperty("NameScope", System.Windows.NameScope)]
public class UnboundColumn : ColumnBase
    Example
    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
