The method specified in the WebPartDisplayModeCancelEventHandler delegate is called when a DisplayModeChanging event is raised.

Page developers can provide custom handlers for Web Parts events by adding an OnDisplayModeChanging attribute to the <asp:webpartmanager> element in a page, and assigning a custom method name to the attribute. A custom handler can also be assigned programmatically. For more information on programmatically assigning an event handler, see How to: Connect Event Handler Methods to Events.
