ASP.NET 4 Unleashed

Using the DragPanel Control

The DragPanel extender control enables you to create a virtual window for your web application. The DragPanel can be used to extend the Panel control so that you can drag the Panel around the page.

The DragPanel extender has the following properties:

• TargetControlID— The ID of the Panel control to drag.

• DragHandleID— The ID of the control that the user clicks to drag the Panel control.
