I am trying out the ASP.NET samples; it starts but I don’t seem to be able to move the bars. Do you know what the problem is?
Your webproject should be Ajax-enabled (download and install from here http://ajax.asp.net/)
Place the Gantt_ASP in an UpdatePanel, and make sure that Gantt_ASP.ClientTimeItems is set to true.
When you have downloaded the ASP.NET set up and samples you can find the projects and source code here C:\Inetpub\wwwroot\GTP.NET.ASP.NET.AJAX\CompleteSource\LetsBuild_Web
