Menu.OnPreRender Method (EventArgs)

Use BaseTrue

This API supports the product infrastructure and is not intended to be used directly from your code.

Raises the PreRender event.

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

protected internal override void OnPreRender(
	EventArgs 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 NIB: 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.
