DataBoundControl.OnPagePreLoad Method

Sets the initialized state of the data-bound control before the control is loaded.

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

protected override void OnPagePreLoad (
	Object sender,
	EventArgs e
)
protected void OnPagePreLoad (
	Object sender, 
	EventArgs e
)
protected override function OnPagePreLoad (
	sender : Object, 
	e : EventArgs
)
Not applicable.

Parameters

sender

The Page that raised the event.

e

An EventArgs that contains the event data.

The OnPagePreLoad method is overridden by the DataBoundControl class to set the BaseDataBoundControl.RequiresDataBinding property to true in cases where the HTTP request is a postback and view state is enabled but the data-bound control has not yet been bound. This scenario is common with controls such as Wizard and MultiView, where the visibility of the control is changed at run time.
