How to validate the fields of Custom Appointment window in EJMVC Schedule?

Platform: ASP.NET MVC |
Control: Schedule

The following steps illustrate how to validate the fields added within the Schedule Custom Appointment window.

Step 1: Create a Schedule sample with Custom Appointment window by referring to the following links,

Sample Location:


Help document Location: [Refer to the document under the topic – “Using Customized Appointment window”]


Step 2: Create the necessary customization Style class and add it to the required fields within the Custom Appointment window for validation purpose as follows.


    .error {
        background-color: #FF8A8A;
    .validation {
        border-color: red;


<script type="text/javascript">
    $("#subject").focusout(function () {
        if ($.trim($("#subject").val()) == "") { 
            $("#subject").addClass("validation");  // Validation for subject
            return false;
    $("#customdescription").focusout(function () {
        if ($.trim($("#customdescription").val()) == "") {
            $("#customdescription").addClass("validation");  // Validation for description
            return false;
    $("#EndTime").focusout(function () {
        if (new Date($("#EndTime").val()).getDate() >= new Date($("#StartTime").val()).getDate()) {
            if (new Date($("#StartTime").val()).getTime() >= new Date($("#EndTime").val()).getTime())         // Validation for Time Interval
                alert("End Time value is less than the Start Time value");

Step 3: Now run the sample. Open the appointment window, click the submit button without filling the subject and description fields. Also check for all other field validations as displayed in the following screenshots.
