siteMapNode, SiteMapPath, Routes, Parameters

Question

Hi, 

   In my RouteConfigs.cs, I have set :

            routes.MapPageRoute("Import", "Import/{ImportType}", "~/Views/ImportData.aspx");

So to call ImportData.aspx, ImportType parameter is to be passed.
To call the above from code-Behind :

            Response.RedirectToRoute("Import", new { ImportType = "Inquiry" });

In ImportData, I access the parameters as :

                if (Page.RouteData.Values["ImportType"] != null)

                {

                    ImportType = (string)Page.RouteData.Values["ImportType"];

                }

In my web.SiteMap file, I added :

        <siteMapNode url="~/Views/ImportData.aspx" title="Import" description="Import From Excel"  />

  Over here I can't find a way to pass Parameter ImportType ?

In my Site.Master, I have added :

                <asp:SiteMapDataSource ID="SiteMapDataSource1" runat="server" ShowStartingNode="False" />

                <span class="breadcrumb">

                    <asp:SiteMapPath ID="SiteMapPath1" runat="server"></asp:SiteMapPath>

                </span>

But, I can't find any sitemap details in it !! 


Any idea how to solve the above 2 queries reg SiteMapNode & SiteMapPath !!
kindly help me.


Thanks
