Grid ActionFailure error handling

[Martha Bailey]

Hi,

I have the following grid:

@(Html.EJ().Grid<MyViewModel>("mygrid")

    .Datasource(ds => ds.Json(Model.MyList.ToList()).RemoveURL("Controller/DeleteOperation").Adaptor(AdaptorType.RemoteSaveAdaptor))

    .EditSettings(edit => { edit.AllowDeleting().ShowDeleteConfirmDialog(); })

    .AllowPaging()

    .AllowSorting()

    .AllowFiltering()

    .FilterSettings(filter => { filter.FilterType(FilterType.Excel); })

    .IsResponsive()

    .Columns(col =>

    {

        col.Field(x => x.model.id).Visible(false).IsPrimaryKey(true).Add();

        col.HeaderText("Name").TextAlign(Syncfusion.JavaScript.TextAlign.Left).Field(x => x.model.name).AllowSorting(true).Width(50).Add();

        col.HeaderText("Description").TextAlign(Syncfusion.JavaScript.TextAlign.Left).Field(x => x.model.desc).AllowSorting(true).Width(50).Add();

        col.HeaderText(" ").IsPrimaryKey(false).Commands(command =>

        {

            command.Type("edit")

           .ButtonOptions(new Syncfusion.JavaScript.Models.ButtonProperties()

           {

               Text = "Edit",

               Click = "onEditClick",

               Width = "30"

           }).Add();

            command.Type(UnboundType.Delete)

            .ButtonOptions(new Syncfusion.JavaScript.Models.ButtonProperties()

            {

                Text = "Delete",

                Width = "40"

            }).Add();

        }).AllowFiltering(false).Width(20).Add();

    }).ClientSideEvents(eve =>  eve.ActionFailure("FailMessage"))

Then my controller:

 [HttpPost]

        public ActionResult DeleteOperation(int key)

        {

            try

            {

                _service.Delete(key);

            }

            catch (Exception ex)

            {

                throw new Exception("Don't do this again");

            }

               //blah

               //blah

               //blah

               //blah

            return Json(mdel, JsonRequestBehavior.AllowGet);

        }

and finally my Javascript error handler:

<script type="text/javascript">

    function FailMessage(args) {

        this.cancelEdit();

        var str = args.error.error.responseText;

        alert(str);

    }

</script>

When I delete the first time the FailMessage is triggered but after dismissing the error message subsequent delete attempts trigger the following error taken from the browser's console:

jquery?v=bXcTrZGqtrcwKAMRnGbw8uWciL3lUOCOt371LT6hr7w1:1 Uncaught TypeError: Cannot read property 'nodeType' of undefined

    at attr (jquery?v=bXcTrZGqtrcwKAMRnGbw8uWciL3lUOCOt371LT6hr7w1:1)

    at a (jquery?v=bXcTrZGqtrcwKAMRnGbw8uWciL3lUOCOt371LT6hr7w1:1)

    at i.fn.init.attr (jquery?v=bXcTrZGqtrcwKAMRnGbw8uWciL3lUOCOt371LT6hr7w1:1)

    at Object.selectRows (ej.web.all.min.js:10)

    at Object.deleteRow (ej.web.all.min.js:10)

    at Object._triggerConfirm (ej.web.all.min.js:10)

    at Object.r (jquery?v=bXcTrZGqtrcwKAMRnGbw8uWciL3lUOCOt371LT6hr7w1:1)

    at Object._trigger (ej.web.all.min.js:10)

    at Object._btnMouseClickEvent (ej.web.all.min.js:10)

    at HTMLInputElement.<anonymous> (ej.web.all.min.js:10)

Initially i did not use the "this.cancelEdit();" but i feel i had to because the grid removes the row regardless.

I used the following link as a starting point:

https://www.syncfusion.com/kb/7135/how-to-return-custom-message-from-controller-when-crud-action-fails

Any idea how I can better handle the error messages while preventing the grid from removing the row in case of an error?

Thank you very much.
