The validation is working good, but does not display the error message in the grid cell.
I have tried couple of options, even though it enters into the logic and fails the validation, no message is displayed.

  $.extend(true, kendo.ui.validator, {
                rules: {
                    // custom rules
                    OrgSchoolID: function (input) {
                                //console.log("Custom Validator fired");
                                // all of the input must have a value
                                //return $.trim(input.val()) !== "";
                                if (input.is("[name=OrgID_FK]") && input.val() === "")
                                    return false;
                                else
                                    return true;

                            },
                },
                messages: { //custom rules messages
                    OrgSchoolID: function (input) {
                        // return the message text
                        return "OrgName is required!";
                    }
                }
            });

I tried this options as well, even though it steps into correctly during debug and returns fail, the Error message is not displayed

 OrgID_FK: {
                        editable: true,
                        type: "number",
                        validation: {
                                IsOrgIDValid: function (input) {
                                            console.log("Validation fired for ORgID Column");
                                            if (input.is("[name=OrgID_FK]") && input.val() === "") {
                                                console.log("Validation failed for OrgID_FK");
                                                input.attr("data-IsOrgIDValid-msg", "OrgName is required!");
                                                return false;
                                            }
                                            return true;
                                        }
                                  
                            } // validation
                    }, // OrgID_FK
