System.Web 2.0.0.0 System.ComponentModel.CancelEventArgs The event is raised when a control attempts to change between edit, insert, and read-only mode, but before the mode actually changes. This allows you to provide an event handler that performs a custom routine, such as configuring the control for a specific mode or canceling the mode change, whenever this event occurs. A object is passed to the event handler, which allows you to determine the mode to which the control is changing, to determine whether the event was raised as a result of the user canceling an edit operation, or to indicate that an insert operation should be canceled. To determine the new mode, use the property. You can also use the property to change to an alternate mode by setting it to one of the enumeration values. Use the property to determine whether the user canceled an edit operation. To cancel an insert operation, set the property to true. For more information about handling events, see Consuming Events.
