    I have a grid that I am using the pop-up editing in. I am using a custom template with drop-downs. The drop-downs have an "Other" option that when selected shows a textbox that you can enter the "Other" details in. This was all in a regular form before I added it to a grid for entry. So I have code for custom validation that would validate these fields if they were showing that worked in a regular form. However, since moving them into the grid pop-up editor, the custom validation is not firing for some reason.

    I'm unsure what to do, I have tried to hook the validator up to the grid like so:

                rules: {
                    otherrequired: function (input) {
                        if ("[data-val-otherrequired]")) {
                            var iVal = input.val();
                            var pFld = $("[name='" + input.attr("data-val-otherrequired-parentfield") + "_input']");
                            if (input[0].id === "DevicePhoneNum") {
                                if (pFld.val().toLowerCase().indexOf("phone") >= 0 && iVal === "") {
                                    return false;
                            if (pFld.val() === "Other" && iVal === "") {
                                return false;
                        return true;
                messages: {
                    otherrequired: function (input) {
                        return input.attr("data-val-otherrequired");
                validateOnBlur: true


    But I'm not sure that this is even the correct way of going about it.

    Any insight into this would be appreciated!

    Hello Dustin,


    Actually there is a default validator that is initialized for the Kendo UI Grid widget in order to validate the user input when a new record is added or an existing one is being edited. We suggest to use that validator and add the custom rules as demonstrated int the Grid / Custom validator editing demo.
