Xceed.Wpf.DataGrid Assembly > Xceed.Wpf.DataGrid Namespace > DataGridCollectionView Class : SourceCollection Property

Gets the underlying un-filtered collection.

Syntax

Visual Basic (Declaration) 
Overrides Public NotOverridable ReadOnly Property SourceCollection As IEnumerable
C# 
public override IEnumerable SourceCollection {get;}

Return Value

An IEnumerable object that represents the underlying collection.

Example

All examples in this topic assume that the grid is bound to the Orders table of the Northwind database, unless stated otherwise.
The following example demonstrates how to delete the selected items from the underlying data view when the delete key is pressed via the PreviewKeyDown event.

<Grid xmlns:xcdg="http://schemas.xceed.com/wpf/xaml/datagrid"> 
  <Grid.Resources> 
    <xcdg:DataGridCollectionViewSource x:Key="cvs_orders" 
                                    Source="{Binding Source={x:Static Application.Current}, 
                                                      Path=Orders}"/>        
         
  </Grid.Resources> 
 
 <xcdg:DataGridControl x:Name="OrdersGrid" 
                       ItemsSource="{Binding Source={StaticResource cvs_orders}}" 
                       PreviewKeyDown="DeleteSelectedRows"> 
 </xcdg:DataGridControl> 
</Grid>
Visual BasicCopy Code
Private Sub DeleteSelectedRows(ByVal sender As Object, ByVal e As KeyEventArgs)
  Dim grid As DataGridControl = TryCast( sender, DataGridControl )
  If Not grid Is Nothing Then
    If e.Key = Key.Delete Then
      If grid.SelectedItems.Count > 0 Then
        ' we keep a copy of the selected items because once the first item is deleted,
        ' the selected items are reset to 0.
        Dim items As ArrayList = New ArrayList( grid.SelectedItems )
        Dim dataView As DataView = TryCast( ( CType( grid.ItemsSource, _
                       DataGridCollectionView ) ).SourceCollection, DataView )
        For i As Integer = items.Count - 1 To 0 Step -1
          dataView.Table.Rows.Remove( CType( items( i ), System.Data.DataRow ) )
        Next i
        grid.CurrentItem = grid.Items( 0 )
      End If
    End If
  End If
End Sub
C#Copy Code
Private void DeleteSelectedRows( Object sender, KeyEventArgs e )
{
DataGridControl grid = sender As DataGridControl;      
If( grid != null )
{
  If( e.Key == Key.Delete )
  {
    If( grid.SelectedItems.Count > 0 )
    {
      // we keep a copy of the selected items because once the first item Is deleted,
      // the selected items are reset To 0 And the source may be automatically modified To
      // reflect the New items.
      ArrayList items = New ArrayList( grid.SelectedItems );
      DataView dataView = ( ( DataGridCollectionView )grid.ItemsSource ).SourceCollection As DataView;
      For( int i = items.Count - 1; i >= 0; i-- )
      {
        dataView.Table.Rows.Remove( ( System.Data.DataRow )items[ i ] );
      }
      grid.CurrentItem = grid.Items[ 0 ];
    }
