FormViewModeEventArgs Class
Assembly: System.Web (in system.web.dll)
The ModeChanging event is raised when a FormView control attempts to switch between edit, insert, and read-only mode, but before the mode actually changes. This allows you to provide an event-handling method that performs a custom routine, such as configuring the FormView control for a specific mode or canceling the mode change, whenever this event occurs.
A FormViewInsertEventArgs object is passed to the event-handling method, which allows you to determine the mode to which the FormView control is changing, to determine whether the ModeChanging event was raised as a result of the user canceling an edit or insert operation, or to indicate that the mode change should be canceled. To determine the new mode, use the NewMode property. You can also use the NewMode property to programmatically specify an alternate mode to which to change by setting it to one of the FormViewMode enumeration values. Use the CancelingEdit property to determine whether this event was raised as the result of the user canceling an edit or insert operation. To cancel the mode change, set the Cancel property to true.
