Hello Raja,

The dll file version you are using targets .NET Framework 3.5. Moreover this version of the controls is rather old and was released more than a year before .NET 4.5 (the framework was released in 2012).

It is recommended to upgrade to the latest version of RadControls (currently 2013.3.1114) as it supports .NET Framework 4.5 and also includes fixes and improvements.

Note that when adding dll files to a web site project or application in Visual Studio the assembly should target the framework version for which the project was created (last two digits in the dll version indicate that).

Additionally I would recommend taking a look at the following articles:
Upgrading RadControls
Upgrade Wizard
