CRUD operations clearing sorts and filters

[Anderson]

Hi,

Currently, my grid clears any and all sort/filters applied to the grid after I perform any CRUD operation. I don't want to do that.
Can someone help?

I know that my ActionResult's return is not correct. I just don't know what should be there.

Here's my Controller

public class ItTasksController : Controller
   {
       private ITaskRepository _repository;

       public ItTasksController() : this(new TaskRepository()){

       }

       public ItTasksController (ITaskRepository repository){
           _repository = repository;
       }

       //
       // GET: /ItTasks/
       public ActionResult Tasks()
       {
           ViewBag.Message = "IT Dev Tasks";
           ViewBag.Link = "Tasks";

           var itTasks = new ItTasksDataContext().tnTasks;

           return View(itTasks);
       }

       [AcceptVerbs(HttpVerbs.Post)]
       public ActionResult Create([DataSourceRequest] DataSourceRequest request, TaskModel task)
       {
           if (ModelState.IsValid)
           {
               _repository.InsertTask(task);
           }
           return RedirectToAction("Tasks");
       }

       [AcceptVerbs(HttpVerbs.Post)]
       public ActionResult Read()
       {
           return RedirectToAction("Tasks");
       }
       [AcceptVerbs(HttpVerbs.Post)]
       public ActionResult Update([DataSourceRequest] DataSourceRequest request, TaskModel task)
       {

           if (ModelState.IsValid)
           {
               _repository.UpdateTask(task);
           }
           return RedirectToAction("Tasks");
       }

       [AcceptVerbs(HttpVerbs.Post)]
       public ActionResult Destroy([DataSourceRequest] DataSourceRequest request, int taskID)
       {
           if (ModelState.IsValid)
           {
               _repository.DeleteTask(taskID);
           }
           return RedirectToAction("Tasks");
       }
   }

Did a quick and dirty fix.

Just chopped off the KendoGrid-mode from the URL and sent it back.

Hello Anderson,

In general when you have a Kendo UI Grid with server operations all the sorting and filtering is done on the server and not on the client. This is why when you edit an item in your grid the sorting is not applied automatically, but you need to call the read() in order to get the sorted data from your remote service. For this purpose you can call the read() of the dataSource on the sync() event (thrown when the data is updated on the server), so you can get again the sorted data. 

Other approach will be to preserve the sorting and filtering and apply the same on the dataBound event, so you can again sort and filter the grid. All these methods and events are explained in the following API reference:
