Feed from this thread Rosy Posted on Mar 12, 2010 (permalink) Hi, I have downloaded and try in install sitefinity3.7, I have windows xp and IIS5.1. The installation created the virtual directory in Telerik-->Sitefinity3.7, I can"t get the Radcontrols. Help me in this issue. Thanks in advance Reply Ivan Dimitrov Ivan Dimitrov Posted on Mar 12, 2010 (permalink) Hello Rosy, Telerik.Web.UI.dll should be in your bin folder. You can make a reference to this dll, add it to the GAC. By default all RadControls can be accessed using "telerik" TagPrefix which is registered in the web.config file. Kind regards, Ivan Dimitrov the Telerik team Do you want to have your say when we set our development plans? Do you want to know when a feature you care about is added or when a bug fixed?
