I am having the following problem. I cannot find a control in the header (ascx page)


I am using this code.

Any help would be appreciated.

have you actually registered your UserControl (.ascx) on your webpage?

You need to use something like this:


<%@ Register TagPrefix="UserControl" TagName="whateverName" Src="~/UserControl/yourUserControl.ascx" %>
