HierarchicalDataBoundControl::OnPagePreLoad Method (Object^, EventArgs^)


The .NET API Reference documentation has a new home. Visit the .NET API Browser on docs.microsoft.com to see the new experience.

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)

virtual void OnPagePreLoad(
	Object^ sender,
	EventArgs^ e
) override


Type: System::Object^

The Page that raised the event.

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.
