Hi Jon,

It is my experience that programmatically adding parameters to a Macro only works if you create the Macro from your codebehind. As I recall it has something to do with the buildup of the Macro and when its loading/calling. Its been a while since I debugged it, but here is what worked for me:

I have a standard <asp:PlaceHolder ID="macroContainer" runat="server"/> on my .ascx page. And I create the Macro in my codebehind:

umbraco.presentation.templateControls.Macro mcr = new umbraco.presentation.templateControls.Macro();
mcr.Alias = "BreadcrumbNav";
mcr.MacroAttributes.Add("boolParam", "true");
mcr.MacroAttributes.Add("IdParam", Id);
this.macroContainer.Controls.Add(mcr);

I have this inside  protected override void OnPreRender(EventArgs e)
I can't remember if it makes a difference to place it inside the protected void Page_Load(object sender, EventArgs e) but try it out. Should work in both Masterpages and Usercontrols.

Morten,

Hey

Thanks for your replies. I've had a read through and had a chat with a friend and I think I may be going around this in the wrong way.

I've accepted Peters answer as the solution because it answers the question but i think i'm going to change the architecture of what i'm doing so there is no reliance on the master page.

The user control should probably be autonomous so I think I'll change it so it goes and gets the information it self rather than relying on the master page sending it the information.

Cheers

Jon
