This panel will reset its position on a postback or page refresh.

ASP.NET AJAX is a free framework for building a new generation of richer, more interactive, highly personalized cross-browser web applications. This new web development technology from Microsoft integrates cross-browser client script libraries with the ASP.NET 2.0 server-based development framework. In addition, ASP.NET AJAX offers you the same type of development platform for client-based web pages that ASP.NET offers for server-based pages. And because ASP.NET AJAX is an extension of ASP.NET, it is fully integrated with server-based services. ASP.NET AJAX makes it possible to easily take advantage of AJAX techniques on the web and enables you to create ASP.NET pages with a rich, responsive UI and server communication. However, AJAX isn't just for ASP.NET. You can take advantage of the rich client framework to easily build client-centric web applications that integrate with any backend data provider and run on most modern browsers.

DragPanel Description

The DragPanel extender allows users to easily add "draggability" to their controls. The DragPanel targets any ASP.NET Panel and takes an additional parameter that signifies the control to use as the "drag handle". Once initialized, the user can freely drag the panel around the web page using the drag handle.

DragPanel Properties

The control above is initialized with this code:

<ajaxToolkit:DragPanelExtender ID="DPE1" runat="server"
    DragHandleID="Panel4" />
  • TargetControlID - The ID of a Panel to make draggable.
  • DragHandleID - The ID of a control that will serve as the "drag handle" for the panel. When the user clicks and drags this control, the panel will move.
