HtmlSelect.SaveViewState Method

  • Reference

Definition

Namespace:
System.Web.UI.HtmlControls
Assembly:
System.Web.dll

Saves any HtmlSelect control view state changes that have occurred since the page was posted back to the server.

protected:
 override System::Object ^ SaveViewState();
protected override object SaveViewState ();
override this.SaveViewState : unit -> obj
Protected Overrides Function SaveViewState () As Object

Returns

Object

The Object that contains the changes to the HtmlSelect view state. If no view state is associated with the object, this method returns a null reference (Nothing in Visual Basic).

Remarks

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 SaveViewState method calls the base class's Control.SaveViewState method to save the control's base view state.

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

Notes to Inheritors

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