Occurs when the System.Web.UI.WebControls.FormView control switches between edit, insert, and read-only mode, but after the mode has changed.
The FormView.ModeChanged event is raised when a System.Web.UI.WebControls.FormView control attempts to switch between edit, insert, and read-only mode, but after the mode actually changes. This allows you to provide an event-handling method that performs a custom routine, such as synchronizing the System.Web.UI.WebControls.FormView control with another control, whenever this event occurs.
