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.
