Remarks

This method has been overridden to check the client browser and configure the validation control for compatibility prior to rendering.

Raising an event invokes the event handler through a delegate. For more information, see Raising an Event.

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 in a derived class, be sure to call the base class's OnPreRender method so that registered delegates receive the event.
