Hello!
I have a gridpanel to change data in db:
                                                                X.GridPanel()
                                                                .ID("GridPanel1")
                                                                .Title("Expander Rows with control")
                                                                .Icon(Icon.Table)
                                                                .Width(800)
                                                                
                                               
                                               
                 .Store(Html.X().StoreForModel().ID("Store1").AutoSync(true).ShowWarningOnFailure(false)
                                                                    .Listeners(l =>
                                                                    {
                                                                        l.Exception.Fn = "onStoreException";
                                                                        l.Exception.Buffer = 10;
                                                                        
                                                                    })
                                                                    .SyncUrl(Url.Action("HandleChanges"))

                                                                )
                                                                .ColumnModel(
                                                                    Html.X().ColumnFor(Model, m => m.id)
                                                                    .ToBuilder<Column.Builder>()
                                                                    .Text("ID")
                                                                    .Width(50),
i change data and correct it in database by update handler:
 public ActionResult HandleChanges(StoreDataHandler handler)
        { List<Requests> readyTask = handler.ObjectData<TestMVC.Models.Requests>();
if (handler.Action == StoreAction.Update)
            { manipulations with db }

return (ActionResult)this.Store(data);
In my DB all changes gone OK, how i can update my grid (after that update some rows must gone, because model data will not grab they in query).
For test i create a button (refresh btn:) ) with handler: this.up('grid').getView().refresh();
after refresh updated row dissaper, BUT grid have a same count of rows (with doble rows)
