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

protected virtual void OnPagePreLoad (
	Object sender,
	EventArgs e
)
protected void OnPagePreLoad (
	Object sender, 
	EventArgs e
)

	sender : Object, 
	e : EventArgs
)
Not applicable.

Parameters

sender

The Page that raised the event.

e

An EventArgs object that contains the event data.

The OnPagePreLoad event handler is used to control when data binding occurs within the life cycle of the page. It does this by setting the internal initialized state of the data-bound control. Because the control's initialized state is set during the PreLoad phase of the page's lifecycle, the OnDataPropertyChanged event handler is called any time a data property of the control is changed after that phase, to signal that the control must re-bind to its data before rendering.
