BindingGroup.BeginEdit Method

Updated: July 2008

Begins an edit transaction on the sources in the BindingGroup.

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

public void BeginEdit()
You cannot use methods in XAML.

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. For the entire example, see Validate the Data of an Object Sample.

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();
}
