Description
How can I implement a custom Timeline view in a Kendo UI Scheduler which allows to change its length dynamically?
Solution
The following example demonstrates how to achieve the desired scenario.
Number of shown days:
<select id="days">
<option>6</option>
<option selected>7</option>
<option>8</option>
</select>
<div id="scheduler"></div>
<script>
var MyCustomTimelistView = kendo.ui.TimelineMonthView.extend({
options: {
name: "MyCustomTimelistView",
title: "Timeline Week",
selectedDateFormat: "{0:D} - {1:D}",
selectedShortDateFormat: "{0:d} - {1:d}",
majorTick: 1440,
numberOfDays: 7
},
name: "MyCustomTimelistView",
calculateDateRange: function() {
// Create the required number of days.
var start = this.options.date,
// start = kendo.date.dayOfWeek(selectedDate, this.calendarInfo().firstDay, -1),
idx, length,
dates = [];
for (idx = 0, length = this.options.numberOfDays; idx < length; idx++) {
dates.push(start);
start = kendo.date.nextDay(start);
}
this._render(dates);
},
previousDate: function() {
var date = new Date(this.startDate());
date.setDate(date.getDate() - this.options.numberOfDays);
return date
}
});
$(function() {
var scheduler = $("#scheduler").kendoScheduler({
date: new Date("2022/6/13"),
startTime: new Date("2022/6/13 07:00 AM"),
height: 600,
views: [{
type: "MyCustomTimelistView",
selected: true,
dateHeaderTemplate: "<span class='k-link k-nav-day'>#=kendo.toString(date, ' dd/M ddd')#</span>"
}],
timezone: "Etc/UTC",
dataSource: {

ownerId: { from: "OwnerID", defaultValue: 1 },
isAllDay: { type: "boolean", from: "IsAllDay" }
}
}
}
}
}).data("kendoScheduler");
$("#days").change(function() {
// Change the number of the days option of the view.
scheduler.setOptions({
numberOfDays: parseInt($(this).val())
});
// Reload the view.
scheduler.view(scheduler.view().name);
});
});
