Hi Siva ,   Add this code in web config,   key = "ValidationSettings:UnobtrusiveValidationMode" value = "None" />

Hi Siva,   I think this is may be from target framework issue in VS 2012,   Read this link , you can get some information about that,   http://www.c-sharpcorner.com/UploadFile/cd7c2e/enabling-unobtrusive-validation-mode-in-Asp-Net-4-5/
