Routing and Rad Controls

[Rod]

Hi -

I'm using a simple routing handler (http://chriscavanagh.wordpress.com/2009/01/20/aspnet-routing-in-vbnet/) for a small project.  When I try to place Rad controls such as a menu or combo box on a page, they work fine if the routing indicates the root directory (where the physical page actually is), however if the routing indicates an "interior" page such as "root/About Us/Bios", the Rad links to the AXD file appear to break - I get no CSS and no JavaScript on the controls.  Have you run across similar situations?

Thanks,

Rod

Hello Rod,

I guess the routing breaks the axd for some reason. Does the built-in ScriptManager control work as expected? I suggest you check for a way to exclude certain paths from routing (which is supported by ASP.NET 3.5 SP1 built-in routing).

Thought that must be it.  The handler I downloaded doesn't include an exclude method, so I'll try and work something out.  Are you aware of any routing handler code samples (in VB) that work well with Rad Controls?

Thanks,

Rod

Hi Rod,

We have an ASP.NET MVC Demo (utilizing the routing) which however is implemented in C#. I suggest you check the following pages which explain how to use ASP.NET routing in WebForms applications:

These seem a lot clearer then the one I was using.  Thanks for the help.

Hi Rod
To simplify, I have on a page RadAjaxPanel with RadGrid inside (Rad controls for asp.net ajax Q1 2009); everything is fine till I'm placing an ajax request - refreshing the grid - then I get this error:

Failed to load viewstate.  The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request.  For example, when adding controls dynamically, the controls added during a post-back must match the type and position of the controls added during the initial request.

Global.asax code:

void Application_Start(object sender, EventArgs e)
    {
        RegisterRoutes(RouteTable.Routes);
    }

public static void RegisterRoutes(RouteCollection Routes)
    {
        Routes.Add(new Route("{resource}.axd/{*pathInfo}", new StopRoutingHandler()));
        var routeHandler = new WebFormRouteHandler<Page>("~/Desktop/Default.aspx");

        Routes.Add(new Route("pg/{page}", routeHandler));

    }

Handler:

public class WebFormRouteHandler<T> : IRouteHandler where T : IHttpHandler, new()
    {
        public string VirtualPath { get; set; }

        public WebFormRouteHandler(string virtualPath)
        {
            this.VirtualPath = virtualPath;
        }

        #region IRouteHandler Members

        public IHttpHandler GetHttpHandler(RequestContext requestContext)
        {
            string pageName
                    = requestContext.RouteData.GetRequiredString("page");
            if (!pageName.Contains(".axd") && pageName.Contains(".aspx"))
            {
                pageNamepageName = pageName.Replace(".aspx", "");
                string virtualPath
                    = ObjectContentValidator.StringIsNullOrEmpty(pageName)
                    ? "~/desktop/default.aspx"
                    : string.Format("~/desktop/default.aspx?page={0}", pageName);
                HttpContext.Current.RewritePath(virtualPath, false);
                return (T)BuildManager.CreateInstanceFromVirtualPath(VirtualPath, typeof(T));
            }
            else
                return (VirtualPath != null)
                    ? (IHttpHandler)BuildManager.CreateInstanceFromVirtualPath(VirtualPath, typeof(T))
                    : new T();
        }

        #endregion
    }

I didn't send entire application because is huge... It's a portal with single page (default.aspx), with modules (custom controls) loadable at runtime.
If I remove url routing/rewriting everything works fine.
Thank you for your time!

PS: I saw a bug in code editor from current page:
I'm using Firefox (3.5.5) and if I'm trying to edit in code preview section using backspace the tab is closed.
I've done it 3 times till I understood to not use backspace... imagine :))

Cheers!

Hi Albert
Previous post was ment for you (Telerik people :) ); unfortunatelly when I wrote it I was very tired and... imagine I've made a confusion.
It's about post from Dec 11 (asp.net routing & url rewriting). Can you help me with that?
Thanks!

Hello Dan,

It is difficult to find what causes this erroneous behavior. I will suggest you open a support ticket and send us a working test project which shows the problem. Thus we will investigate it locally and advice you further.

Best wishes,
