Occurs before changing the current View's DetailView.ViewEditMode property value.
The ViewEditModeChanging event handler receives an argument of the CancelEventArgs type. The following properties provide information specific to this event.
|Cancel||Gets or sets a value indicating whether the event should be canceled.|
By default, this event is raised when the Edit, SaveAndClose or Cancel built-in Action is executed. This behavior is provided by the WebModificationsController. So, it makes sence is ASP.NET Web applications only.
