I have a RadEditor in the user control of a SharePoint 2010 Visual Webpart in Visual Studio 2010. The Show SmartTag option is disabled when I right click the control in design view. I would like access to the SmartTag so I can add the required entries in the web.config for the HttpHandler to use the SpellCheck and ImageManager. I tried adding the entries manually but continue to get an error message saying that I need to add the handlers to the web.config.
