The ModeChanging event is raised when a DetailsView control attempts to change between edit insert and read-only mode but before the CurrentMode property is updated. This allows you to provide an event handler that performs a custom routine such as canceling the mode change whenever this event occurs. http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.detailsview.modechanging.aspx
