HierarchicalDataBoundControl.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
)

Parameters

sender
Type: System.Object
The Page that raised the event.
e
Type: System.EventArgs
An EventArgs that contains the event data.

The OnPagePreLoad sets the 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.
