[Solved] About Grid refresh after update

[Gary]

Hi,

It's a bug?
In hierarchy grid, and Inline Edit mode.

When I updated, and the RETURN result is null,
But why the Grid still has data?

MVC APSX:

<%:

        Html.Kendo().Grid<CarryingCapacityMD>()

            .Name("Grid").ToolBar(commands => commands.Create())

            .Columns

            (

                columns =>

                {

                    columns.Bound(o => o.Tonnage).Width(75).Format("{0:0.00}");

                    columns.Bound(o => o.CageCount).Width(75);

                    columns.Command

                    (

                        commands =>

                        {

                            commands.Edit();

                            commands.Destroy();

                        }

                    ).Width(180).Title("操作");

                }

            )

            .ClientDetailTemplateId("freightInformationTemplate")

            .DataSource

            (

                dataSource =>

                    dataSource.Ajax()

                        .Model

                        (

                            model =>

                            {

                                model.Id(p => p.CarryingCapacityID);

                            }

                        )

                        .Read("_AjaxCarryingCapacityList", "Configurations")

                        .Update("_AjaxCarryingCapacityUpdate", "Configurations")

                        .Destroy("_AjaxCarryingCapacityDelete", "Configurations")

                        .Create("_AjaxCarryingCapacityInsert", "Configurations")

            )

            .Editable(editing => editing.Mode(GridEditMode.PopUp))

    %>

    <script id="freightInformationTemplate" type="text/kendo-tmpl">

        <%:

            Html.Kendo().Grid<FreightInformation>()

                .Name("FreightInfo_#=CarryingCapacityID#")

                .Columns

                (

                    columns =>

                    {

                        columns.Bound(o => o.LocationName).Width(75);

                        columns.Bound(o => o.Mileage).Width(75);

                        columns.Bound(o => o.Freight).Width(75).Format("{0:￥0.00}");

                        columns.Command(command => { command.Edit(); });

                    }

                )

                .DataSource

                (

                    dataSource => dataSource.Ajax().ServerOperation(true)

                        .Model

                        (

                            model =>

                            {

                                model.Id(p => p.FreightID);

                                model.Field(p => p.LocationName).Editable(false);

                                model.Field(p => p.Mileage).Editable(false);

                            }

                        )

                        .Read("_AjaxGetFreightInfoListByCarryingCapacityID", "Configurations", new { carryingCapacityID = "#=CarryingCapacityID#" })

                        .Update("_AjaxLocationUpdateForCarryingCapacity", "Configurations")

                )

                //.Events(events => { events.SaveChanges("onSave");})

                .Editable(editing => editing.Mode(GridEditMode.InLine))

                //.ToolBar(commands => { commands.Save(); })

                .ToClientTemplate()

         %>

Behind Code:

[AcceptVerbs(HttpVerbs.Post)]

public ActionResult _AjaxLocationUpdateForCarryingCapacity(FreightInformation updatedFreightInformation)

{

    if (ModelState.IsValid)

    {

        freightRepository.UpdateForCarryingCapacity(updatedFreightInformation);

    }

    freightRepository = new FreightRepository();

    return Json(freightRepository.GetFreightInfoByCarryingCapacityID(updatedFreightInformation.CarryingCapacityID)); //this result is null

}

But after update,
the grid is still show data.

Hello,

You need to use the ToDataSourceResult method as explained in the documentation. Basically you do not need to return the record - just the ModelState.
