The Login.OnPreRender(EventArgs) method implements the System.Web.UI.Control.OnPreRender(EventArgs) method to notify the System.Web.UI.WebControls.Login control to perform any necessary prerendering steps before saving view state and rendering content.

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

The Login.OnPreRender(EventArgs) 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.
