Virtual Vertical Grouping

The vertical virtualization feature of the Scheduler groups the resources vertically and optimizes the rendering of the view by using a DOM virtualization.

When you enable the virtual vertical grouping, a batch of resources (such as rooms, attendees, equipment, and more) are displayed as rows along the left side of the Scheduler. As the user scrolls down, additional resources are dynamically loaded and rendered. At the same time, the time slots remain on the vertical axis for Day and Week views and on the horizontal axis for the Month view. As a result, each resource is represented as a separate row, allowing the user to review all events associated with each resource one below the other. Vertical virtualization is suitable when dealing with an extensive list of resources and allows the user to focus on specific resources.

The views that support virtual vertical grouping are: Day, Week, WorkWeek, and Month.

To enable the vertical virtualization of the Scheduler's resources:

1. Add the Group() configuration and specify the names of the resources in the Resources() option.
2. Set the Orientation() option to SchedulerGroupOrientation.Vertical. The available options of the SchedulerGroupOrientation setting are Default (horizontal), Horizontal, and Vertical. The Scheduler requests and retrieves the data as usual and renders the events based on the grouped resources.

3. Include the Virtual(true) option to each view that must be virtualized.

       @(Html.Kendo().Scheduler<MeetingViewModel>()
           .Name("scheduler")
           .Resources(resource =>
           {
               resource.Add(m => m.RoomID)
               .Title("Room")
               .Name("Rooms")
               .DataTextField("Text")
               .DataValueField("Value")
               .DataColorField("Color")
               .BindTo(new[] {
                       new { Text = "Meeting Room 101", Value = 1, Color = "#6eb3fa" },
                       new { Text = "Meeting Room 201", Value = 2, Color = "#f58a8a" }
               });
           })
           .Views(views =>
           {
               views.DayView(view => view.Virtual(true));
               views.WeekView(view => view.Selected(true).Virtual(true));
               views.WorkWeekView(view => view.Virtual(true));
               views.MonthView(view => view.Virtual(true));
           })
           .Group(group => group.Resources("Rooms").Orientation(SchedulerGroupOrientation.Vertical)) // "Rooms" matches the "Name()" option of the defined resource within the "Resources()" configuration.
           ...// Additional configuration.
       )
