problem with parsecontrol

hi i have a problem with the parsecon开发者_Go百科trol() method

Control c = this.ParseControl("<uc1:GroupListControl NickName='HARD' GroupName='STUFF' runat='server' ID='Abekat' />"); <-- error Unknown server tag 'uc1:GroupListControl'.

Control c3 = ParseControl("<asp:button id='Button3' text='Btn3' runat='server' />"); <-- this works just fine

why do i get the error from my own webusercontrol ? i have registered it in the html page like this

<%@ Register src="~/webcontrols/GroupListControl.ascx" tagname="GroupListControl" tagprefix="uc1" %>

Greetings Entvex

You should try to include "Register" directive into you ParseControl statement, like the following:

Control c = 
                this.ParseControl("<%@ Register src=\"GroupListControl.ascx\" tagname=\"GroupListControl\" tagprefix=\"uc1\" %> <uc1:GroupListControl ID=\"GroupListControl1\" runat=\"server\" />"); 

For additional information see this article.

Also maybe Page.LoadControl method will be useful for you.
