DataBoundControl.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 method is overridden by the DataBoundControl class to set 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 Wizard and MultiView, where the visibility of the control is changed at run time.
