Virtual Scrolling in Vue Schedule component

To achieve better performance in the Scheduler when loading a large number of resources and events, we have added virtual scrolling support in the timeline views to load a large set of resources and events instantly as you scroll. You can dynamically load large number of resources and events in timeline view of the Scheduler by setting true to the allowVirtualScrolling property within the timeline view-specific settings. The virtual loading of events is possible in Agenda view, by setting allowVirtualScrolling property to true within the agenda view specific settings.

    var timelineEventTemplateVue = Vue.component('timelineTemplate', {
        template: `<div class='template-wrap' style='{background: data.PrimaryColor}'>
            <div class="subject" style='{background: data.SecondaryColor};'>{{data.Subject}}</div></div>`,

        data: function () {
            return {
                selectedDate: new Date(2018, 4, 1),
                timelineEventTemplate: function (e) {
                    return {
                        template: timelineEventTemplateVue

  .e-schedule .template-wrap .subject {
        padding: 10px 25px;

    .e-schedule .template-wrap {
        width: 100%;

    .e-schedule .e-timeline-month-view .e-resource-left-td {
        width: 150px;

For now, the virtual loading of resources and events is available only for timeline views. In the future, we plan to port the same virtual loading on all other applicable Scheduler views.
