Menu.OnPreRender Method

This API supports the .NET Framework infrastructure and is not intended to be used directly from your code.
This member overrides BaseDataBoundControl.OnPreRender(EventArgs), and more complete documentation might be available in that topic.

Raises the PreRender event.

Namespace:  System.Web.UI.WebControls
Assembly:  System.Web (in System.Web.dll)

abstract OnPreRender : 
        e:EventArgs -> unit  
override OnPreRender : 
        e:EventArgs -> unit

Parameters

e
Type: System.EventArgs

An EventArgs that contains the event data.

The OnPreRender method is called by the Menu control to raise the PreRender event. It is generally used by control developers when extending the Menu class.

Raising an event invokes the event handler through a delegate. For more information, see Events and Delegates.

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.
