    The event handler receives an argument of type RoutedEventArgs containing data related to this event. The following RoutedEventArgs properties provide information specific to this event.

    PropertyDescription
    Handled  
    OriginalSource  
    RoutedEvent  
    Source  
    Remarks
    The EditBeginning and EditEnding events are raised immediately after their respective BeginEdit and EndEdit methods are called to allow the process to be canceled. In the EditBeginning event, if the Cancel property of the CancelRoutedEventArgs received as a parameter is set to true, the cell or row that raised the event will be prevented from entering edit mode. Likewise, if Cancel is set to true in the EditEnding event, the cell or row will be prevented from exiting edit mode.
    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 subscribe to the Cell.EditBeginning and EditBegun events as well as how to handle and cancel them.The following code provides the implementation of the EditBeginning and EditBegun event handlers.The following code provides the implementation of the EditBeginning and EditBegun event handlers.
