is caused due to conflict in the Syncfusion assemblies being used. Take a look at the .aspx file and/or the web.config file and ensure that you are using the proper version of the Syncfusion Assemblies. For instance if you are using Visual Studio 2003 and Essential Studio 220.127.116.11, the version number of the Syncfusion Assemblies used by VS.NET will be 3.300.1.0, so you should ensure that .aspx and/or the web.config files also use this version.
