Remarks
Handle the CustomDrawView event to draw graphic objects on the surface of the Scheduler view. Use e.Cache and e.Graphics as drawing tools. Other properties of the CustomDrawObjectEventArgs instance can be ignored.
Note
The Date Navigation Bar is painted after the scheduler view and can overlap your drawings. Set the SchedulerDateNavigationBar.Visible property to false to hide this visual element.
To avoid possible issues, turn animation effects off when you custom draw a View.
schedulerControl1.DayView.AllowScrollAnimation = false;
schedulerControl1.WorkWeekView.AllowScrollAnimation = false;
schedulerControl1.FullWeekView.AllowScrollAnimation = false;
schedulerControl1.MonthView.AllowScrollAnimation = false;
schedulerControl1.CustomDrawView += (s, e) => {
e.Cache.FillRectangle(e.Cache.GetSolidBrush(Color.Red), new Rectangle(0, 100, e.Bounds.Width, 100));
};
