How to prevent grid from retrying update on error

[Quentin]

Hi all,

I have been browsing the forums and stack overflow and can't find a solution to this.

I implemented the generic Kendo "error" js method as shown in the demos in order to show errors on updates, and then I added the error to my modelstate.

When the grid tries to update and an error is thrown - it automatically retries up to 4 time. Is there a way to prevent this retry from happening?

I am using MVC4 - and a standard MVC controller.

Here is my controller error handler:

catch (Exception ex)
            {
                ModelState.AddModelError("Error", ex.Message);
                return Json(ModelState.ToDataSourceResult(), JsonRequestBehavior.AllowGet);
            }

Here is the js code for showing the error:

function error(e) {
    if (e.errors) {
        var message = "Errors:\n";
        $.each(e.errors, function (key, value) {
            if ('errors' in value) {
                $.each(value.errors, function () {
                    message += this + "\n";
                });
            }
        });

        alert(message);
    }
}

The grid uses a standard Async update method in order to perform the update, and this goes to an MVC controller and not an API controller.

My question again: When the grid tries to update and an error is thrown - it automatically retries up to 4 time. Is there a way to prevent this retry from happening?

Hi Quentin,

I tried to reproduce the problem locally but to no avail – everything is working as expected on our side (no additional requests are made after the first request returns error). Could you please provide runable project where the issue is reproduced and more information about the exact steps to reproduce it on our side? This would help us pinpoint the exact reason for this behavior.

Kind Regards,

Hi Vladimir,

When you mentioned that you couldn't recreate it I decided to look at the code more carefully.

I had some additional events that were being fired on certain actions so I removed them and tried again.

The problem was that I had a refresh method running as below. I removed it and the retry stopped occurring.

function gridRequestEnd(e) {
    if (e.type == "destroy" || e.type == "update") {
        //execute your custom code
        $("#CreativesGrid").data("kendoGrid").dataSource.read();
        $("#CreativesGrid").data("kendoGrid").refresh();
        $("#CreativesGrid").data("kendoGrid").dataSource.sync();

Thanks for the help,
Quentin
