Hi,

I guess you are talking about using the diagram in an ASP.NET environment. If that is the case, please take a look at the Flow Chart Builder Demo example. You can implement a pseudo drag and drop in WebForm but note that this will generate a lot of client -> server -> client communication and traffic and put a heavy load on your server, so it's better to implement a workaround as shown in this example. The main idea is to let the user click a shape to select it and then move that shape to the new location the user clicks on.
