I have a user control which takes in a content picker parameter and then renders the children of the content picker value.

When I insert the macro onto a template and select a page via the content picker, the correct value is displayed.

But for some reason when I view the site, the user control value is always the root value (1050).

If I hardcode the source value in the user control, then it renders the children correctly.

I have supplied the template and user control below.

Any ideas why this might be happening?

<%@ Master Language="C#" MasterPageFile="~/masterpages/Master.master" AutoEventWireup="true" %>

<asp:Content ContentPlaceHolderID="masterContent" runat="server">
    <div id="mainContent" class="fc">
      
      <div class="navigation">
        <umbraco:Macro ID="Macro2" CssClassName="" CssId="" StopLevel="6" StartLevel="2" Alias="Navigation" runat="server"></umbraco:Macro>    
      </div>

       <div id="content">
            <umbraco:Item ID="Item2" Field="bodyText" runat="server" ></umbraco:Item>
         
            <asp:ContentPlaceHolder Id="contentContent" runat="server"></asp:ContentPlaceHolder>
         
           <umbraco:Macro source="1051" Alias="TestUC" runat="server"></umbraco:Macro>
       </div>

       <umbraco:Macro Alias="SidePanels" runat="server"></umbraco:Macro>
    </div>
 
</asp:Content>
