make sure that you declare your user control in aspx page with id="c"

You must declare user control with the same ID. If you dragged and dropped the user control in the aspx page, then the ID should be UserControl1, you can alter the ID by goto property bag or switch to HTML code and change ID of user control to "c" like you want

This will help you.


DropDownlistuc1 is the usercontrol and dropdownlist1 is the id .

It works fine.
