Error Creating Control - RadGrid

[MSQ]

I've created a new web project using 'Telerik Web Site', added an existing web page (.aspx) which had a RadGrid added to it.

When I open up this page in Design, I get the following error. The Bin folder was created by the project and does have all DLLs including Telerik.Web.UI/Design

Error Creating Control - RadGrid

Unknown server tag:RadGrid

Error: Could not load file or assembly 'RadGrid.Net2' or one of its dependencies.

A bit more info..

The web.config file does contain he following tag:

           <controls>
                <add tagPrefix="telerik" namespace="Telerik.Web.UI" assembly="Telerik.Web.UI" />
            </controls>

Never mind, I have figured it out.
I need to install the older version of controls to make it to work
