I'm trying to figure out how I should handle a drag/drop operation.

The source will be a tree node and the destination will be an Infragistics WebGrid.

Can anyone suggest the way I should go about this.  I'm using VB as the code-behind.  However, I get the feeling I'll need to do this with JAVA script.  I was reading this article which talks about ASP.NET AJAX and the 'Sys.Preview.UI._DragDropManager' class:

The article goes on to say,  "... the ' DragDropManager ' is the glue that binds drag sources and drop targets together. Without it, you'd be writing a ton of code to make drag-and-drop user interfaces work—especially if they had to work in a variety of browsers."

Any thoughts here??

Thanks!!
