Hello,

In order to change local DataSource's data you should use its data method passing the new data. This will automatically trigger DataSource change event and notify the associated widgets (in this case the Grid widget) to repaint themselves.

dataSource.data(myData);

Note that calling read method will repopulate the DataSource. In your case where local transport is used, this will result in filling  the DataSource with the initial (provided when it was created) data.Regards,

How would I do it if I'm following the example code? My data is updating because when I click the search and retrieve the data it comes back wtih the changes.

Grid:

<div id="grid">

    @(Html.Kendo().Grid(Model)

        .Name("CodeManager")

    .Columns(columns =>

    {

        columns.Bound(p => p.CodeID);

        columns.Bound(p => p.Title);

        columns.Bound(p => p.Status);

        columns.Command(command => { command.Edit(); }).Width(200);

    })

    .ColumnMenu()

    .ToolBar(toolBar => toolBar.Create().Text("Add New Code"))

    .Sortable()

    .Scrollable()

    .Groupable()

    .Pageable()

    .Filterable()

    .Selectable(selectable => selectable.Mode(GridSelectionMode.Multiple))

    .Resizable(resize => resize.Columns(true))

    .DataSource(dataSource => dataSource

        .Ajax()

        .Events(events => events.Error("error_handler"))

        .ServerOperation(false)

        .Model(model => model.Id(p => p.Id))

         .Update(update => update.Action("Code", "CodeManager", new { classifications = @ViewBag.SelectedCatgory }))

         .Create(create => create.Action("Code", "CodeManager"))

        )

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

        )

</div>

Controller: I tried called the get again after the update and that didn't work.

HttpPost]

        public ActionResult Code(CodeModel codeModel, string classifications)

        {

            if (ModelState.IsValid)

            {

 

                codeModel.Category = classifications;

                var code = codeModel.FromModel();

 

                if (code.Id > 0)

                    _codeRepository.Update(code);

                else

                    _codeRepository.Insert(code);

 

                var criterion = new Criterion("Category", Operator.Equals, codeModel.Category);

                var model = _codeRepository.GetList(criterion).ToModel();

 

                return View(model);

            }

Thanks
