Leaving Grid in EDIT MODE when Using Custom errors and ModelState

[Buddy]

I followed the example for Ajax custom errors and server side modelstate errors, however, the grid (inline editing) goes out of Edit Mode after  my javascript error event is called.

We would like to leave the grid in error mode.

Not using .cancelChanges();

// javascript 

function grid_error(e) {
    var grid = $("#CPRProductLineGrid").data("kendoGrid");
    var knotify = $("#popupNotification").data("kendoNotification");

    if (e.errors) {
        var message = "";

        $.each(e.errors, function(key, value) {
            if ('errors' in value) {
                $.each(value.errors, function() {
                    message += this + "<br />";
                });
            }
        });

        knotify.show({
            title: "Validation Error",
            message: message
        }, "error");
  
       
       //grid.cancelChanges();

    }
}

// controller

           foreach (var item in  validator.GetValidationErrors())
                {
                    ModelState.AddModelError("GroupCode1", item);
                }

           return Json(ModelState.ToDataSourceResult());

Hi Buddy,

In order to prevent the Grid from closing the edit form, you should handle the dataBinding event and prevent it.

function grid_error(e) {
    var grid = $("#CPRProductLineGrid").data("kendoGrid");
    var knotify = $("#popupNotification").data("kendoNotification");

    if (e.errors) {
      /*...*/
      grid.one("dataBinding", function(args) {
          args.preventDefault();
      });

    }
}

This does not work in 2014.3.1411 the args are ignored, the sync is fired and the edit mode always closes.

Hi Buddy,

There should be no difference in the version used. Here you can find a test page which demonstrates the discussed approach. Also I have created a short video which captures the test page behavior. Please take a look maybe I'm missing something obvious.
