Hi,

code:

<asp:HyperLink ID="HyperLink1" runat="server"  href='<%# GetRouteUrl("RouteForCat", new {id = Eval("id"), Title= GetTitle(Eval("Title"))})%>'
         Text='<%# Eval("Title") %>'> 
</asp:HyperLink>


void Application_Start(object sender, EventArgs e) 
{
     // Code that runs on application startup
    RegisterCustomRoutes(RouteTable.Routes);
}

void RegisterCustomRoutes(RouteCollection routes) 
{
    routes.MapPageRoute("RouteForCat", "{id}/Article/{title}", "~/Details.aspx");
}

details.aspx

if (Page.RouteData.Values["id"].ToString() != null)
{
    string strId = Page.RouteData.Values["id"].ToString();
    //passing id for blog_id
    Blog_id.Value = Page.RouteData.Values["id"].ToString();
}
