        Recently ive downloaded Telerik dll from the Website (2011.3.1305.35) and when Im trying to build the application using this dll on V2.0 framewrok, i face some compatibility issues with System.web.Extension.

        Error 43 C:\Prabhu\Working Folder\Prototype\Prototype\Prototype\MasterPage\Proto.Master: ASP.NET runtime error: The base class includes the field 'UpdatePanel1', but its type (System.Web.UI.UpdatePanel) is not compatible with the type of control (System.Web.UI.UpdatePanel). C:\Prabhu\Working Folder\Prototype\Prototype\Prototype\MasterPage\Proto.Master 160 1 Prototype

    Hello Prabhu,

    As you have probably noticed, the version downloaded of our controls doesn't contain .Net 2.0 assemblies. The error that you receive is a bit self explanatory, the telerik controls need a higher version of the System.Web.Extensions assembly, than the one you are referencing, which is due to the fact that you are developing a .Net 2.0 project.

    You could build 2.0 assemblies which could be used in your project, but the source code of our controls is not distributed with the trial version. You have to purchase them in order to get it.
