12.3. Summary

The ASP.NET Futures CTP provides a drag-and-drop engine that you can use to add drag and drop to web pages. Typically, drag and drop in web pages is implemented with draggable items (DOM elements that can be dragged around the page) and drop targets (elements that allow draggable items to be dropped onto their area).

You can easily implement draggable items and drop targets as Microsoft Ajax components that implement the IDragSource or IDropTarget interface in order to receive feedback from the DragDropManager, a global JavaScript object that coordinates a drag-and-drop operation.
