I have aKendo Grid, I have added custom validation on multiple columns. It's working as expected for all the columns, though it's not working for the columns of the type checkbox. It shows the error message even if the checkbox is unchecked.


columns.Bound(config => config.X).Title("X").HeaderHtmlAttributes(new { @class = "grid-headercustom" }).
ClientTemplate("#if(data.X == 1)" + "{#<span>Y</span>#}" + "else{#<span>N</span>#}#").
HtmlAttributes(new { @class = "grid-rowcustom" }).HtmlAttributes(new { style = "font-size:12px" }).Filterable(ftb => ftb.Enabled(false));


$.extend(true, kendo.ui.validator, {
    rules: {
        RateV: function (input, params) {
            if (input.is("[name='X']")) {
                var grid = $("#grid-pricefeedconfiguration").data("kendoGrid");
                var row = input.closest("tr");
                var dataItem = grid.dataItem(row);
                if (dataItem.X == true && dataItem.Y <= 0) {
                    input.attr("data-RateV-msg", "X must be greater than zero when the Y is ticked");
                    return false;
                }
            }
            
            return true;
            }
        },
        messages: {
            RateV: function (input) {
                // return the message text
                return input.attr("data-val-X");
            }
        }
    });
})(jQuery, kendo);
