I recently had the same problem and to amke matters worst the client's ISP did not allow you to create virtual directpries! The ONLY solution that seemed to work waws to place ALL of the user control into the application's root directory instead oof into a subdirectory called "controls"... The controls were placed always at the same level or in directories BELOW the one the aspx files were in and this solved the problem. Bill SerGio

Hi, Thanx for that information...i've somehow managed to bypass all that is to learn on Control naming. But I see now why these names are generated. :)
