Today I've been looking at adding a landing page to the Orders node within Umbraco. To do this I followed a could of blog posts including http://www.publicvoid.dk/ExtendingTreesInUCommerceAdmin.aspx and watched the umbraco videos. I managed to override the CreateRootNode elemnt and have my landing page be displayed wth little problem

    public class loadOrderExport : UCommerce.Umbraco.Menu.LoadOrders
    {
        // Constructor is required by base type
        public loadOrderExport(string application)
            : base(application)
        {
        }

        protected override void CreateRootNode(ref XmlTreeNode rootNode)
        {
            RootNode.Action = string.Format("javascript:{0}", "parent.right.document.location.href = 'UCommerce/Dashboard/ExportOrders.aspx';");
        }
    }

But then my problem was attempting to create that new page. My new page ExportOrders.aspx used the master page UmbracoTabView.Master and I have a user control inside the ContentArea from the master page. I could see my content being rendered but it was not being displayed correctly. Eg: still had a loading bar showing and was not sitting inside a tab or anything. 

I'm presuming I've just missed doing something If someone could point me in the right direction that would be great.

Thanks John
