Hello Babu,

You have referenced to old RadControls in your application and using the newer version on page. You need to update the reference in the web.config to match the version of the deployed assembly.

I hope the following links would be helpful for you.

Hello Babu,

Web.config file seems ok, but also in the aspx page the Telerik.Web.UI assembly should be registered instead of the old RadTabStrip.Net2 assembly, replace:


<%@ Register Assembly="RadTabStrip.Net2" Namespace="Telerik.WebControls" TagPrefix="radTS" %>

with:

<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>


Kind regards,
