Remarks
This method notifies the server control to perform any necessary pre-rendering steps prior to saving view state and rendering content.
Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.
The OnPreRender method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.
Notes to Inheritors
When overriding OnPreRender(EventArgs) in a derived class, be sure to call the base class's OnPreRender(EventArgs) method so that registered delegates receive the event.
