Hello

When I'am trying to add new RadControl to my web page I got this error :
Error Creating Control - RadTabStrip1Failed to create designer 'Telerik.Web.UI.RadTabStrip, Telerik.Web.UI, Version=2010.1.415.20, Culture=neutral, PublicKeyToken=121fae78165ba3d4'

or this error :
Error Creating Control - RadComboBox1Could not load file or assembly 'Telerik.Web.UI, Version=2010.1.415.20, Culture=neutral, PublicKeyToken=121fae78165ba3d4' or one of its dependencies. The system cannot find the file specified.

And I added this code to web.config :
<add path="Telerik.Web.UI.DialogHandler.aspx" verb="*" type="Telerik.Web.UI.DialogHandler, Telerik.Web.UI, Version=2010.1.415.20, Culture=neutral,PublicKeyToken=121fae78165ba3d4" validate="false"/>
        
            <add path="Telerik.Web.UI.SpellCheckHandler.axd" verb="*" type="Telerik.Web.UI.SpellCheckHandler, Telerik.Web.UI, Version=2010.1.415.20, Culture=neutral, PublicKeyToken=121fae78165ba3d4" validate="false"/>






Thanks

Hi Ali,

Please make sure that the 'Telerik.Web.Design.dll' file is present in your project's bin folder. Also checkout the following links which describes possible solutions.
