I am getting warnings on all asp tags that Validation():Element 'element name' is not supported. it is happening only with one file in which i used GGC. in design view it displays error that "The page contains markup that is not valid when attached to master page". It was working fine and i didn't made any change in code. However It runs fine plus there is no problem with other pages. Anyone have idea whats wrong with it????

Hi Rizwan,

Thank you for your interest in Essential Grid.

The reported issue may be due to the controls registration directives in the page, so could you please share your sample files so that we can look into it and suggest a solution quickly.

Please let me know if you have any concerns.
