BindingGroup.BeginEdit Method

Definition

Namespace:

System.Windows.Data

Assembly:

PresentationFramework.dll

Begins an edit transaction on the sources in the BindingGroup.

public:
 void BeginEdit();

public void BeginEdit ();

member this.BeginEdit : unit -> unit

Public Sub BeginEdit ()

Examples

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

void stackPanel1_Loaded(object sender, RoutedEventArgs e)
{
    // 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();
}

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

Remarks

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
