ASCX control not visible in design mode in VS2008

Question

I have a custom ASCX control that is not visible in design mode in VS2008. It used to be, I changed nothing and now when I switch back to design mode, it is not visible. Has anyone ever face this situation?

Answer 1

Is that possible to post the code for the control?

Have you tried restarting Visual Studio?

What else is on the page where you are dropping the user control?

Answer 2

Usually this will occur if you have bad tags in your ASCX file. Do this, open the ASCX (not the code-behind file) and hit CTRL+K then CTRL+D. That will reformat the tags cleanly. If you get an error, find it and fix it and it should resolve your problem.
