BindingGroup.BeginEdit Method

Begins an edit transaction on the sources in the BindingGroup.

Namespace:  System.Windows.Data
Assembly:  PresentationFramework (in PresentationFramework.dll)

'Declaration
Public Sub BeginEdit

If the sources in the BindingGroup support discarding pending changes, you can call BeginEdit to begin the edit transaction, call CommitEdit to save the pending changes, call CancelEdit to discard the pending changes.

For each object in Items that implements IEditableObject, BeginEdit calls IEditableObject.BeginEdit

The following example calls BeginEdit when a window loads to begin the edit transaction.

		Private Sub stackPanel1_Loaded(ByVal sender As Object, ByVal e As RoutedEventArgs)
			' Set the DataContext to a PurchaseItem object.
			' The BindingGroup and Binding objects use this as
			' the source.
			stackPanel1.DataContext = New PurchaseItem()

			' Begin an edit transaction that enables
			' the object to accept or roll back changes.
			stackPanel1.BindingGroup.BeginEdit()
		End Sub
