I noticed, that when using a validation for kendo grid fields, only some fields get the k-invalid class. This can be easily seen on the demo page: http://demos.telerik.com/kendo-ui/grid/editing-custom-validation .
All the empty fields are correctly validated, but only ProductName fields has the k-invalid class. The Unit Price and Units In Stock don't (they still kave the k-valid class, although there is tooltip saying that field is required). So my problem is that I want to style invalid fields with red background etc, and it simply doesn't work for numeric fields.
Is that a known issue? Any workarounds for now?
