title: problem with parsecontrol
body: <p>hi i have a problem with the parsecontrol() method</p>
  
  <pre><code>Control c = this.ParseControl("&lt;uc1:GroupListControl NickName='HARD' GroupName='STUFF' runat='server' ID='Abekat' /&gt;"); &lt;-- error Unknown server tag 'uc1:GroupListControl'.
  
  Control c3 = ParseControl("&lt;asp:button id='Button3' text='Btn3' runat='server' /&gt;"); &lt;-- this works just fine
  </code></pre>
  
  <p>why do i get the error from my own webusercontrol ? i have registered it in the html page like this</p>
  
  <pre><code>&lt;%@ Register src="~/webcontrols/GroupListControl.ascx" tagname="GroupListControl" tagprefix="uc1" %&gt;
  </code></pre>
  
  <p>Greetings Entvex</p>
