Hi

I am creating a custom backend page and I want to use the umbraco uicontrols like the umbracopanel and propertypanel.

I am using

MasterPageFile="~/umbraco/masterpages/umbracoPage.Master"

and inheriting from the UmbracoEnsuredPage.

but when I try doing something like this:

<%@ Register Assembly="controls" Namespace="umbraco.uicontrols" TagPrefix="cc1" %>
<asp:Content id="Content1" contentplaceholderid="body" runat="server">
  <cc1:UmbracoPanel ID="Umbracopanel1" runat="server" Text="">          
      <cc1:PropertyPanel ID="PropertyPanel1" runat="server" Text="test">                          
       </cc1:PropertyPanel>
  </cc1:UmbracoPanel>

I get a red squiggly under "umbraco" in the register assembly bit saying it's ambiguous and under all the umbraco ui controls I have no intellisense.

I am referencing the following dlls

• businesslogic
• clientDependence.Core
• cms
• controls
• interfaces
• umbraco.core
• umbraco.datalayer
• umbraco

It's not a complete show stopper as everything still compiles and when I put my page into the umbraco site it all works fine but it's getting difficult to develop like this!

What am I missing?

Thanks
