how do you set a url routing routevalue to a hyperlink's navigate url property in an aspx page?

Question

If the following routes:

 routes.MapPageRoute(
           "Build",      // Route name
           "build",      // Route URL
           "~/build.aspx" // Web page to handle route
        );

     routes.MapPageRoute(
       "Type",      // Route name
       "build/{type}",      // Route URL
       "~/build.aspx" // Web page to handle route
    );

       routes.MapPageRoute(
       "Project",      // Route name
       "build/{type}/{project}",      // Route URL
       "~/build.aspx" // Web page to handle route
    );

 routes.MapPageRoute(
       "Task",      // Route name
       "task/{type}/{project}",      // Route URL
       "~/task.aspx" // Web page to handle route
    );

How do I set a hyperlinks navigate url in the .aspx (not code behind) to the route named 'task' where type = 'tool' and project = 'excel'?

For example, in a grid view template field:

  <asp:TemplateField>
    <ItemTemplate>
      <asp:HyperLink runat="server" ID="btnUp" Text='<%# Eval("ProjectID") %>'
        NavigateUrl='<%# GetRouteUrl("Task",
          new System.Web.Routing.RouteValueDictionary
          {
            {"type", "tool" },
            {"project" , "excel" }
          }) %>' />
    </ItemTemplate>
  </asp:TemplateField>

or, you can set parameters from data source:

  <asp:TemplateField>
    <ItemTemplate>
      <asp:HyperLink runat="server" ID="btnUp" Text='<%# Eval("ProjectID") %>'
        NavigateUrl='<%# GetRouteUrl("Task",
          new System.Web.Routing.RouteValueDictionary
          {
            {"type", Eval("Type") },
            {"project" , Eval("ProjectType") }
          }) %>' />
    </ItemTemplate>
  </asp:TemplateField>
