0	Hi, Your problem seems that it is mainly caused by the System Enviroments. Ajax-enabled program runs depend on .Net Framework2.0 or above.(If your application developed based on .NET Framework 3.5, please make sure it should be runs on .Net Framework 3.5) Sometimes , the newly created ajax application runs on .Net Framework 1.1(IIS). So please check it first. Second, you should check whether Asp.Net 2.0 Ajax Extensions V1.0 has been installed or not. Lakhan Singh Tech Lead BeyondKey System Pvt. Ltd. Indore, M.P.
