X.Panel()
                .ID("South")
                .Region(Region.South)
                .Title("Hasta Listesi")
                .Frame(true)
                .Height(375)
                .Collapsible(true)
                 .Layout(LayoutType.Form)
                .ItemsFromPage(this, "~/Views/Istatistik/AltListe.cshtml")

AltList.cshtml I want to get the Id of the selected row in the Grid panel in Partial View and process it. I'm new to Mvc Ext.net, can you please help.

  Html.X().GridPanel()
                .ID("PersonelGrid")
                .Width(1520)
                .Height(300)
                .SelectionModel(X.RowSelectionModel().Mode(SelectionMode.Single).ID("RowSelectionModel1").SelectedIndex(0))
                .ForceFit(true).Store(Html.X().Store()
        .DataSource(Model)
        .ID("Store1")
        .Model(Html.X().Model()
        .Fields(
        new ModelField("Id"),
        new ModelField("Adi"),
        new ModelField("Soyadi"),
        new ModelField("Tel"),
        new ModelField("Mail"),

        new ModelField("Aktif", ModelFieldType.Boolean)
        )))
                .ColumnModel(
        X.Column().Text("Id").DataIndex("Id").Hidden(true),
        X.Column().Text("Adi").DataIndex("Adi"),
        X.Column().Text("Soyadi").DataIndex("Soyadi"),

                .BottomBar(Html.X().PagingToolbar().StoreID("Store1").HideRefresh(false)
                 .Items(X.Toolbar().Items(
                 X.Button()
                .Text("Tüm Listeyi Yazd?r")
                .IconCls("add32")
                .Icon(Icon.Printer)
                .Region(Region.East)

I want to get the id of the selected row with the button on the panel.

 X.Panel()
                            .Title("Hasta ??lemleri")
                            .Frame(true)
                            .Padding(0)
                            .Height(300)
                            .Width(100)
                            .Items(X.Toolbar()
                               .Layout(LayoutType.Column)
                            .Items(

                 .Height(60)
                 .Width(100)
                .DirectEvents
                        (de =>
                        {
                            de.Click.Action = "Submit";
                            de.Click.EventMask.ShowMask = true;
                            de.Click.ExtraParams.Add(new Parameter()
                            {
                                Name = "selection",
                                Value = "App.PersonelGrid.getSelectionSubmit().getSelectionModelField().getValue()",
                                Mode = ParameterMode.Raw
                            
                            });

                        }
                        )

I'm new to Mvc.Ext.net. Can you please help me on how to do it. I have reviewed the relevant examples. but I could not reach the result. "App.PersonelGrid.getSelectionSubmit().getSelectio nModelField().getValue()", I can get the index of the selected row with this method. But I could not get the id of the relevant row. thanks
