Description
How can I set the cell background color based on the slot date in the Kendo UI for jQuery Scheduler?
Solution
The following example demonstrates how to achieve the desired behavior by using the slotTemplate and allDaySlotTemplate configuration options. Note that the slotTemplate is supported when views.type is set to day, week, workWeek, or timeline views. The allDaySlotTemplate is supported only for the day, week, and workWeek views.
<div id="scheduler"></div>
<style>
/* Remove the padding of scheduler slots */
.k-scheduler-table td, .k-scheduler-table th
{
padding: 0;
}
</style>
<script>
function getColorBasedOnHour(date) {
var difference = date.getTime() - kendo.date.getDate(date);
var hours = difference / kendo.date.MS_PER_HOUR;
if (hours >= 8 && hours < 12) {
return "#CC66FF";
} else if (hours >= 13 && hours < 17) {
return "#CC0099";
} else {
return "#33CCFF";
}
}
$(function() {
$("#scheduler").kendoScheduler({
date: new Date("2025/6/13"),
