System.Web.UI.WebControls.HierarchicalDataBoundControl.OnPagePreLoad Method

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

Syntax

protected override void OnPagePreLoad (object sender, EventArgs e)

Parameters

sender
The System.Web.UI.Page that raised the event.
e
An EventArgs that contains the event data.

Remarks

The HierarchicalDataBoundControl.OnPagePreLoad(object, EventArgs) sets 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 System.Web.UI.WebControls.Wizard and System.Web.UI.WebControls.MultiView where the visibility of the control is changed at run time.

Requirements

Namespace: System.Web.UI.WebControls
Assembly: System.Web (in System.Web.dll)
Assembly Versions: 2.0.0.0
Since: .NET 2.0
