Error 500 unhandled

[Christian]

Dear support team,

I have a grid which registeres an error event. When the model validation fails, the event is correctly triggered and I get a messagebox.

Next i tried to insert a dummy javascript (<script>alert('aaa')</script>) into the textbox.
MVC reacts on it with an error 500 ('a potential malicious request was detected')
However the onError event function is not triggered now.

@(Html.Kendo().Grid<MyViewModel>()

      .Name("kendoGrid")

      .DataSource(dataSource => dataSource

          .Ajax()

          .Model(model => {              model.Id(i => i.Id);          })

          .Create(create => create.Action("_Create", "Controller"))

          .Read(read => read.Action("_Index", "Controller"))

          .Update(update => update.Action("_Update", "Controller"))

          .Destroy(destroy => destroy.Action("_Delete", "Controller"))

          .Events(events => events.Error("onError")) // <----------- Register Error Event

      )

      .ToolBar(toolbar => toolbar.Create().Text("New"))

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

      .Columns(column => {

          column.Bound(i => i.Name);

          column.Command(cmd => {

              cmd.Destroy();

              cmd.Edit();

          });

      })

      )

 

<script type="text/javascript">

    function onError(e) {
                          alert("test");

        if (e.errors) {

            var message = "The folowing errors occured:\n";

            $.each(e.errors, function(key, value) {

                if (value.errors) {

                    message += value.errors.join("\n");

                }

            });

            bootbox.alert(message);

        } else {

            bootbox.alert("An unknown error occured");

        }

    }

</script>

Any ideas what I've done wrong here?

btw my version is 2014.Q2

A second issue is, that I don't get a bootbox window. Instead I get a standard message box. Perhaps you have a clue on that too.

thank you,
Chris

Hello Chris,

Could you provide a runnable sample that replicates the problem? The dataSource error event should be triggered for both custom errors and an error response.

Hello Daniel,

Thank you for your response. While preparing the sample for you, it came out I had a duplicate javascript funtion with the same function name still enabled. Sorry, my fault. Problem solved.
