I am trying to add an infragistics grid control to my application. After I add the grid and ran the application, I got this error message. I went and added the reference which then shows up correctly in my web.config file....but when I view the source code for the web page, the assembly was not added. I tried to add it manually but that did not work. Can someone tell me what I have done wrong or what the proper way to add this reference to my application?
