Validation function on one column is validating also on all others

[CS]

I added a validation function to a field, but also all the other fields with validation: true get validated with this function which is totally wrong. Is that an intended behaviour?

Hi Stefan,

Basically current behavior is expected - in your validation function you should check if the current input element is the desired before executing the validation code. Please check the example below:

ProductName: {
    validation: {
        required: true,
        productnamevalidation: function (input) {
            if (input.is("[name='ProductName']") && input.val() != "") {
                input.attr("data-productnamevalidation-msg", "Product Name should start with capital letter");
                return /^[A-Z]/.test(input.val());
            }

            return true;
        }
    }
},

Also you can check the following demo of the grid with custom validation:
