after placing a radmenu on my master page and creating a page from it, when I run the page I get the following error

Error 2 The type or namespace name 'RadMenu' does not exist in the namespace 'Telerik.WebControls' (are you missing an assembly reference?) 

Do I have to manually add the references for each control I want to use ?  Dont they get placed in the GAC for development ?

Hi,

Have you added the NameSpace using Telerik.WebControls in the code behind?

Princy.
