Sorry, but it is a really bad idea to use a windows control in a web app. They are 2 very, very different things. See the solutions below.

Check the UserControl references are proper by adding the WindowsUsercontrol dll.

It's somehow misleading...It's true that you can do this in a very awkward way, but IMHO you MUST point out all the pitfalls of such a solution...for instance it's works only on specific browsers on specific OS. A lot of security issues accompanied with various popup messages on the client...

Kornfeld , I agree that its an awkward way of doing it.But if OP asked as a suggestion should I would have stated that. Also, Tadit has suggested to use WebUserControl which was the right one.

You can't. Instead create a Web UserControl and include that in Web Page. You are mixing Windows and Web App, which is not possible.

Refer - ASP.NET User Controls[^].
