[Edmund Herbert]

Hi I am using MySql with Entity Framework and am having issue with posting Updated Data from the Grid back to controller update ActionResult

I am using VS2017 and asp.net MVC 5 application with latest version of Syncfusion and Entity Framework

The reurned data fro an update are null


@{
ViewBag.Title = "Home Page";
}

Here

@(Html.EJ().Grid("Editing")
.Datasource(ds => ds.Json((IEnumerable)ViewBag.datasource).UpdateURL("/Test/Update")
.InsertURL("/Test/Insert").RemoveURL("/Test/Remove").Adaptor(AdaptorType.RemoteSaveAdaptor))
.AllowSorting()

.EditSettings(edit => { edit.AllowAdding().AllowDeleting().AllowEditing(); })
.ToolbarSettings(toolbar =>
{
toolbar.ShowToolbar().ToolbarItems(items =>
{
items.AddTool(ToolBarItems.Add);
items.AddTool(ToolBarItems.Edit);
items.AddTool(ToolBarItems.Delete);
items.AddTool(ToolBarItems.Update);
items.AddTool(ToolBarItems.Cancel);
});
})
.AllowPaging()
.Columns(col =>
{
col.Field("CarTrackID").HeaderText("ID").IsPrimaryKey(true).TextAlign(TextAlign.Right).Width(90).Add();
col.Field("CarTrackClientName").HeaderText("Client Name").TextAlign(TextAlign.Right).Width(90).Add();
col.Field("CarTrackEmail").HeaderText("Email").TextAlign(TextAlign.Right).Width(80).Add();
}))

public class TestController : Controller
{
// GET: Test
public ActionResult Index()
{
var dma = new Car();

dma.Configuration.ProxyCreationEnabled = false;

var result = dma.cartracks.ToList();

ViewBag.datasource = result.ToList();

return View();
}

public ActionResult Update(cartrack hm)
{
return null;
}
}


Thanks in advance

Hi Edmund, 

Thanks for contacting Syncfusion support. 

We have checked your query and we are not able to reproduce the reported issue. We have also prepared a sample in grid with latest version by performing CRUD operation that can be downloaded from the below link 

Link: http://www.syncfusion.com/downloads/support/forum/134542/ze/EJGrid233413129 

Refer the code example 

@(Html.EJ().Grid<object>("Editing") 

        .Datasource(ds => ds.Json((IEnumerable<object>)ViewBag.datasource).Adaptor(AdaptorType.RemoteSaveAdaptor).UpdateURL("/Home/Update").InsertURL("/Home/Insert").RemoveURL("/Home/Remove")) 

        ... 

        .AllowPaging() 

        .Columns(col => 

        { 

... 

        }) 

 

) 

 

 

public ActionResult Update(Order value) 

        { 

             

                db.Entry(value).State = EntityState.Modified; 

                db.SaveChangesAsync(); 

                

                return Json(value, JsonRequestBehavior.AllowGet); 

            

        } 

        public ActionResult Insert(Order value) 

        { 

            db.Orders.Add(value); 

            db.SaveChanges(); 

            var data = db.Orders.ToList(); 

            

            return Json(data, JsonRequestBehavior.AllowGet); 

        } 

        public ActionResult Remove(int key) 

        { 

            Order order = db.Orders.Find(key); 

            db.Orders.Remove(order); 

            db.SaveChanges(); 

            return Json(order, JsonRequestBehavior.AllowGet);
