In trying to register a user control, I get the following error:
Validation (XHTML 1.0 Transitional): Element 'register' is not supported
Seems simple enough. Any ideas?
I wrote in VB
<%@ Register Src="Controls/UserProfile.ascx" TagName="UserProfile" TagPrefix="mb" %>
and placed it in the page:
<mb:UserProfile ID="UserProfile1" runat="server" />
