在umbraco模板中的页面加载时呈现宏控件

Question

I am trying to load the razor script which exists as a separate macro in umbraco. I am using umbraco 4.7.0

I am basically doing geo-targeting and hence need to run the script each time on a page load. so I am looking for something like :

 <script type="c#" runat="server">
protected void Page_Load(object sender, EventArgs e)
  {
    Call the Macro here
  }

Obviously I can do this in the template

 <umbraco:Macro Alias="GeoTargetting" runat="server" />

but I need to call this macro before any control is loaded in the page.

PLease help.

Thanks

This appears to work alright:

Template:

<umbraco:Macro Alias="Sandbox" runat="server"></umbraco:Macro>
<asp:Label runat="server" ID="Label1" Text="Yo"></asp:Label>

Macro Script:

@using System.Web.UI.WebControls
@using umbraco.MacroEngines
@inherits DynamicNodeContext
@{
    Page page = HttpContext.Current.Handler as Page;
    page.Load += new EventHandler(page_Load);
}

@functions
{
    static void page_Load(object sender, EventArgs e)
    {
        Page page = sender as Page;
        Label label = FindControlRecursive(page, "Label1") as Label;
        label.Text = "Hello";
    }

    private static Control FindControlRecursive(Control Root, string Id)
    {
        if (Root.ID == Id)
            return Root;

        foreach (Control Ctl in Root.Controls)
        {
            Control FoundCtl = FindControlRecursive(Ctl, Id);

            if (FoundCtl != null)
                return FoundCtl;
        }

        return null;
    }
}

Note: The FindControlRecursive() method is from this forum thread .
