Blazor Scheduler Example - Drag Between Schedulers
This example illustrates how to drag and drop events among multiple Scheduler. You can drag events from one Scheduler to another.
        In this example, EventDragArea is used to drag a range of events from one Scheduler to another.
        The OnDragStop event of the Scheduler is triggered when an item is dropped from one Scheduler onto another.
        Within the OnDragStop event, the AddEventAsync method is used to add the dropped event to the target Scheduler,
        and the DeleteEventAsync method is used to remove the dragged event from the source Scheduler.
