Restores the HtmlSelect control's view state information from a previous page request that was saved by the SaveViewState() method.

protected:
 override void LoadViewState(System::Object ^ savedState);

protected override void LoadViewState (object savedState);

override this.LoadViewState : obj -> unit

Protected Overrides Sub LoadViewState (savedState As Object)

Parameters

savedState: Object

An Object that represents the control state to be restored.

Remarks

This method is used primarily by the .NET Framework infrastructure and is not intended to be used directly from your code. However, control developers can override this method to specify how a custom server control restores its view state. For more information, see ASP.NET State Management Overview.

The HtmlSelect control's view state is stored as a Triplet object. The First field of the Triplet object holds the HtmlSelect control's base view state. The Second field of the Triplet object holds the ListItemCollection collection represented by the Items property. The Third field of the Triplet object holds the selected indices represented by the SelectedIndices property. The LoadViewState method calls the base class's HtmlContainerControl.LoadViewState method to restore the control's base view state.

The LoadViewState method is used primarily by control developers extending the functionality of the HtmlSelect control.

Notes to Inheritors

When overriding LoadViewState(Object) in a derived class, be sure to call the base class's LoadViewState(Object) method so that the HtmlSelect control's view state is properly managed.
