Hello hedayat,

You have probably forgotten to add a ScriptRegistrar after the Grid. Please check this blog post for further details.

Hi hedayat,

The first error is rather strange. Can you reproduce it on our online demos?

The second error indicates that some server-side exception has occurred while making the request. Using FireBug or Fiddler would show what the stacktrace is. You can also try putting a breakpoint in your action method called via ajax.

1- about my first problem, i couldn't underestand what do U mean

2- about second problem: i checked it, I did find any problem. please look at my code:

aspx:

<%= Html.Telerik().Grid(Model)
      .Name("Grid")
        .Columns(cols =>
                  { cols.Add(o => o.ReceiptNo);
                  cols.Add(o => o.ReceptionDate);
                  cols.Add(o => o.DriverFamily);
                  cols.Add(o => o.DriverName);

                  })
                .ServerBinding(serverBinding => serverBinding.Action("Index", "VRS_Estimate", new { ajax = ViewData["ajax"] }))
                .Ajax(ajax => ajax.Enabled((bool)ViewData["ajax"]).Action("IndexAjax", "VRS_Estimate"))
                .Scrollable(scrolling => scrolling.Enabled((bool)ViewData["scrolling"]))
                .Sortable(sorting => sorting.Enabled((bool)ViewData["sorting"]))
                .Pageable(paging => paging.Enabled((bool)ViewData["paging"]))
                .Filterable(filtering => filtering.Enabled((bool)ViewData["filtering"]))
        %>

-----------Cs ---------

 

 public ActionResult Index(bool? ajax, bool? scrolling, bool? paging, bool? filtering, bool? sorting)
        {
            ViewData["ajax"] = ajax ?? true;
            ViewData["scrolling"] = scrolling ?? true;
            ViewData["paging"] = paging ?? true;
            ViewData["filtering"] = filtering ?? true;
            ViewData["sorting"] = sorting ?? true;
            ViewData["Message"] = "Welcome to ASP.NET MVC!";

            return View(_VRS_ReceptionService.GetVRS_Receptions());

        }
        [GridAction]
        public ActionResult IndexAjax()
        {
            return View(new GridModel<VRS_Reception>
            {
                Data = _VRS_ReceptionService.GetVRS_Receptions()
            });
        }

Hello hedayat,

About the first problem - do you reproduce it when browsing our online grid demos?

About the second - please try running with debugger and see if the IndexAjax method is not throwing any exceptions. HTTP code 500 means "Internal Server Error" and the most common reason is server-side exception.

By the way you don't need all those variables - ajax, scrolling, paging etc. They seem to be taken from the first look example and are not required at all by the grid. They were only used to enable the configurator. Please check this demo for a simpler ajax binding configuration.

Hi.

1) I could solve the first problem, it was because of another scripts that added to my forms.

2) I've created another project with Telerik extention and in that ajax works very well, but i can't find out the problem in my main project, why telerik grid rase an Error with Ajax mode. Grid works very well without Ajax.

Tnx a lot

Hi hedayat,

Unfortunately I cannot help without first knowing what the exception is. Please try running your project with attached debugger. I am afraid I cannot help you further.
