I have project B, which is a class library project. I compile it and it creates a dll. In my project B which is a web application project, I add a reference to the A.dll, and I click on toolbox and select choose item, navigate to dll, and click on it. The control does not show up on my toolbox. When I right click my toolbox and select "show all", the control is there, but it's grayed out. I have been searching for an answer to this for a couple of days now, nothing changes. Please help.
