Validating Custom Fields

Thread ID:

Asked On January 13, 2019 02:04 PM UTC

I'm sorry that I have to bother you with this, I couldn't find an example in the documentation although I am sure it does exist.
In https://ej2.syncfusion.com/aspnetcore/Schedule/EditorValidation#/material is a description of how to attach validation rules to members of 
<e-eventsettings-fields>, e.g. <e-field-subject name="Subject" validation="ValidationRules"></e-field-subject>

I have added additional fields to the Editor window using the popupOpen Event; one of those is e.g. an Option to select if the appointment is open, closed or to be approved by the Owner for other people.
So now I have an e-field named ListOption, which is a DropDown of [{"Id":0,"Name":"Unknown"},{"Id":1,"Name":"Open"},{"Id":2,"Name":"Closed"},{"Id":3,"Name":"Approve"}];

On saving the Appointment, I would like to make sure that ListOption is not empty, and that the value is between 1 and 3 (ie not "None").

How can I attach that validation?
Thank you very much for your assistance. Please let me know should you require a full example and I shall provide one on stackblitz.

Hi Stefan, 

Thank you for contacting Syncfusion support. 

We have checked your query and you can achieve your requirement by making use of popupOpen event. Please refer the below code example and sample link. 

    ViewData["Title"] = "Home Page"; 
<ejs-schedule id="schedule" height="550px" selectedDate="new DateTime(2018, 2, 11)" actionBegin="onActionBegin" popupOpen="onPopupOpen" editorTemplate="#EventEditorTemplate"> 
    <e-schedule-eventsettings dataSource="@ViewBag.AppointmentData"> 
<script id="EventEditorTemplate" type="text/x-template"> 
    <table class="custom-event-editor" width="100%" cellpadding="5"> 
                <td class="e-textlabel">List Option</td> 
                <td colspan="4"> 
                    <input type="text" id="EventType" name="EventType" class="e-field" style="width: 100%" required /> 
                <td class="e-textlabel">Subject</td> 
                <td colspan="4"> 
                    <input id="Subject" class="e-field e-input" type="text" value="" name="Subject" style="width: 100%" /> 
                <td class="e-textlabel">Start Time</td> 
                <td colspan="4"> 
                    <input id="StartTime" class="e-field" type="text" name="StartTime" /> 
                <td class="e-textlabel">End Time</td> 
                <td colspan="4"> 
                    <input id="EndTime" class="e-field" type="text" name="EndTime" /> 
                <td class="e-textlabel">Description</td> 
                <td colspan="4"> 
                    <textarea id="Description" class="e-field e-input" name="Description" rows="3" cols="50" 
                              style="width: 100%; height: 60px !important; resize: vertical"></textarea> 
<script type="text/javascript"> 
    function onActionBegin(args) { 
        if (args.requestType === 'eventCreate' || args.requestType === 'eventChange') { 
            var data; 
            if (args.requestType === 'eventCreate') { 
                data = args.data[0]; 
            } else if (args.requestType === 'eventChange') { 
                data = args.data; 
            var scheduleObj = document.getElementById('schedule').ej2_instances[0]; 
            if (!scheduleObj.isSlotAvailable(data.StartTime, data.EndTime)) { 
                args.cancel = true; 
    function onPopupOpen(args) { 
        if (args.type === 'Editor') { 
            if (typeof (document.getElementById("EventType_Error")) == 'undefined') { 
                document.getElementById("EventType_Error").style.display = "none"; 
            var formElement = args.element.querySelector('.e-schedule-form'); 
            var statusElement = args.element.querySelector('#EventType'); 
            if (!statusElement.classList.contains('e-dropdownlist')) { 
                var dropDownListObject = new ej.dropdowns.DropDownList({ 
                    placeholder: 'Choose status', value: statusElement.value, 
                    fields: { text: 'Value', value: 'Id' }, 
                    dataSource: [{ "Id": 0, "Value": "Unknown" }, { "Id": 1, "Value": "Open" }, { "Id": 2, "Value": "Closed" }, { "Id": 3, "Value": "Approve" }], 
                    change: function () { 
                        if (typeof (document.getElementById("EventType_Error")) != 'undefined') { 
                            document.getElementById("EventType_Error").style.display = "none"; 
                statusElement.setAttribute('name', 'EventType'); 
            var startElement = args.element.querySelector('#StartTime'); 
            if (!startElement.classList.contains('e-datetimepicker')) { 
                new ej.calendars.DateTimePicker({ value: new Date(startElement.value) || new Date() }, startElement); 
            var endElement = args.element.querySelector('#EndTime'); 
            if (!endElement.classList.contains('e-datetimepicker')) { 
                new ej.calendars.DateTimePicker({ value: new Date(endElement.value) || new Date() }, endElement); 
            // Add the custom validation message to the dropdown 
            var validator = (formElement).ej2_instances[0]; 
            validator.addRules('EventType', { required: true }); 
@*Alignment CSS for error message*@ 
<style type="text/css"> 
    .e-tooltip-wrap.e-schedule-error { 
        top: 38px !important; 
        margin-left: 200px;
