save: function(e) {
                                    // Get the data item being saved
                                    var dataItem = e.model;

                                    // Access properties of the data item and perform actions accordingly
                                    var addressType = dataItem.intInternetAddressTypeID;
                                    var inputField = dataItem.strInternetAddress;

                                    // Perform validation or other actions based on the properties
                                    if (addressType === "2") {
                                        // Email validation for input field
                                        var emailRegex = /^[^\s@@]+@@[^\s@@]+\.[^\s@@]+$/;
                                        if (!emailRegex.test(inputField)) {
                                            // Set validation message on the corresponding cell
                                            e.container.find("[name=strInternetAddress]").closest("td").attr("data-strInternetAddress-msg", "Invalid email address format");
                                            e.preventDefault(); // Prevent saving the record
                                        }
                                    } else if (addressType === "10") {
                                        // Phone number validation for input field
                                        var phoneRegex = /^[0-9]+$/;
                                        if (!phoneRegex.test(inputField)) {
                                            // Set validation message on the corresponding cell
                                            e.container.find("[name=strInternetAddress]").closest("td").attr("data-strInternetAddress-msg", "Invalid phone number format");
                                            e.preventDefault(); // Prevent saving the record
                                        }
                                    }
                                },

i also enable the tooltip from databound
dataBound: function (e) {
   e.sender.element.find("[data-strInternetAddress-msg]").each(function () {
                                    $(this).kendoTooltip({
                                        position: "bottom",
                                        content: $(this).attr("data-strInternetAddress-msg"),
                                    });
                                });
}but tooltip is not showing in the page , it preventing from saving but not showing tooltip after inspection i found that it creating this html

<td role="gridcell" data-container-for="strInternetAddress" data-strinternetaddress-msg="Invalid email address format"><input type="text" class="k-input k-textbox k-valid" name="strInternetAddress" required="required" data-required-msg="Internet Address is required" data-bind="value:strInternetAddress"></td>
