Page.OnPreLoad Method

Raises the PreLoad event after postback data is loaded into the page server controls but before the OnLoad event.

Namespace: System.Web.UI
Assembly: System.Web (in system.web.dll)
protected virtual void OnPreLoad (
	EventArgs e
)
protected void OnPreLoad (
	EventArgs e
)
protected function OnPreLoad (
	e : EventArgs
)
Not applicable.

Parameters

e

An EventArgs that contains the event data.

The OnPreLoad method is called after all postback data returned from the user is loaded. At this stage in the page's life cycle, view-state information and postback data for declared controls and controls created during the initialization stage are loaded into the page's controls.

Controls created in the OnPreLoad method will also be loaded with view-state and postback data.

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

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