Tab character is added to cell when grid.onValidationError.subscribe is used

[whoishacking.com]

Hi,

I use this to display validator error message:

grid.onValidationError.subscribe(function (e, args) {

  alert(args.validationResults.msg);

});

 

When tab is used to navigate and cell has error then alert pops up, but tab character itself is added to cell value (not good).

If above code is not used then cell has red border on error and tab character is not added to cell value (right behavior).

Is there any fix for this?
