HierarchicalDataBoundControl.OnPagePreLoad(Object, EventArgs) Method

Definition

Namespace:

System.Web.UI.WebControls

Assembly:

System.Web.dll

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

protected:
 override void OnPagePreLoad(System::Object ^ sender, EventArgs ^ e);

protected override void OnPagePreLoad (object sender, EventArgs e);

override this.OnPagePreLoad : obj * EventArgs -> unit

Protected Overrides Sub OnPagePreLoad (sender As Object, e As EventArgs)

Parameters

sender

Object

The Page that raised the event.

e

EventArgs

An EventArgs that contains the event data.

Remarks

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.
