SortDescriptions Property (DataGridCollectionViewBase)

Visual Basic
C#

'Declaration
 
Public Overrides ReadOnly Property SortDescriptions As SortDescriptionCollection

'Usage
 
Dim instance As DataGridCollectionViewBase
Dim value As SortDescriptionCollection
 
value = instance.SortDescriptions

public override SortDescriptionCollection SortDescriptions {get;}

Property Value

A SortDescriptionCollection containing the SortDescription objects that describe how the items in the collection are sorted in the view.

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 subscribe to the CollectionChanged event of the DataGridCollectionView.SortDescriptions collection's INotifyCollectionChanged interface implementation to be notified when sorting applied to a grid's columns changes.

Visual Basic

Protected Overrides Sub OnInitialized(ByVal e As EventArgs)
  MyBase.OnInitialized(e)


  Dim view As DataGridCollectionView = TryCast(Me.OrdersGrid.ItemsSource, DataGridCollectionView)
  AddHandler (CType(view.SortDescriptions, INotifyCollectionChanged)).CollectionChanged,
                                           AddressOf SortCollectionChanged
End Sub
Private Sub SortCollectionChanged(ByVal sender As Object, ByVal e As NotifyCollectionChangedEventArgs)
  Debug.WriteLine("Sort changed")

End Sub

}
private void SortCollectionChanged( object sender, NotifyCollectionChangedEventArgs e )
