Help document Location: Using Customized Appointment window: http://docs.syncfusion.com/aspnet/schedule/customization

Step 2: Add the following code examples within the style and script section.

CSS

<style>
    .error {
            background-color: #FF8A8A;
        }   
    .validation {
        border-color: red;
    }
</style>

JavaScript

<script type="text/javascript">
 
    $("#subject").focusout(function () {
        if ($.trim($("#subject").val()) == "") { 
            $("#subject").addClass("validation");  // Validates subject
            return false;
        }
    })
    $("#customdescription").focusout(function () {
        if ($.trim($("#customdescription").val()) == "") {
            $("#customdescription").addClass("validation");  // Validates 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())         // Validates Time Interval
                alert("End Time value is less than the Start Time value");
        }
    })
</script>

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