Hi,
 
I have been using Telerik controls, I was using server binding, but I have to use Ajax binding, that is not working properly, I am getting Error "Error! The requested URL did not return JSON asp.net mvc"
Following is the Code in My Controller
[GridAction]
        [Authorize(Roles = "Admin")]
        public ActionResult Edit(int id)
        {
            Contact model = _cService.getContact(id, applicationID);
            GetContactType();
            if (model != null)
                return View(new GridModel());
            else
            return View();
        }
 

        //
        // POST: /Contact/Edit/5
        [GridAction]
        [AcceptVerbs(HttpVerbs.Post)]
        public ActionResult Edit(int id, Contact model)
        {
            try
            {                         
                _cService.SaveContact(model, applicationID); 
                return RedirectToAction("Index");
            }
            catch
            {
                return Json(new GridModel());
            }
        }
        public virtual JsonResult GetParents()
        {
            return GetContactsByType(2);
        }
        public virtual JsonResult GetContactsByType(int? id)
        {
            List<contact> list;
            if (id.HasValue)
              list=  _cService.GetContactCollections(applicationID).Where(x => x.ContactTypeId == id.Value).ToList();
            else
                list = _cService.GetContactCollections(applicationID).ToList();
            return new JsonResult
            {
                Data = list,
                JsonRequestBehavior = JsonRequestBehavior.AllowGet, // you may or may not need this line, depending upon your server config
            };
        }</contact>
 
and following Code in my view
  @(Html.Telerik().Grid(Model)
        .Name("Contact")
              //  .ToolBar(commands => commands.Insert())
       .DataKeys(keys => keys.Add(c => c.Id))
        
        .DataBinding(dataBinding => 
        {
             
            dataBinding.Ajax()
            
            .Update("Edit", "Contact", new { mode = GridEditMode.InForm, type = GridButtonType.Text })
            .Delete("Delete", "Contact", new { mode = GridEditMode.InLine, type = GridButtonType.Text });
        })
                   
        .Columns(columns =>
        {
            columns.Command(commands =>
            {
                commands.Edit().ButtonType(GridButtonType.Text);
                commands.Delete().ButtonType(GridButtonType.Text);
            }).Width(180).Title("Manage");
          columns.Template(o=> @Html.ActionLink(o.LastName, "Details",new {id=o.Id})).Title("LastName").Width(130);
          columns.Bound(o => o.FirstName).Width(160);
          columns.Bound(o => o.Address).Width(110);
          columns.Bound(o => o.CellPhone).Width(110);
          columns.Bound(o => o.HomePhone).Width(110);
          
        })
What I can do this Error, this error arise using Alert box, I have tried Modifying telerik.grid.min.js I have removed the line that,then it does not shows me error but also does not work.
Can somebody please give me Some suggestions.

Given that you've bought the Telerik library, I'd think their support would be the best place to look for help with their controls

Looks like you've asked this on every site on the web, except the Telerik site...
