A Graphics object which provides a means for painting.

Remarks

The Graphics property returns an object which represents the painting surface and provides a means for painting. You can use methods and properties of this object to paint text, graphics primitives and images.

Examples

The following sample code handles the SchedulerControl.CustomDrawAppointment event to manually paint appointments. The image below shows the result.

CustomDrawAppointment

using DevExpress.XtraScheduler;
using DevExpress.XtraScheduler.Drawing;
using System.Drawing.Drawing2D;
private void schedulerControl1_CustomDrawAppointment(object sender, CustomDrawObjectEventArgs e) {
    TimeLineAppointmentViewInfo tlvi = e.ObjectInfo as TimeLineAppointmentViewInfo;
    // This code works only for the Timeline View.
    if(tlvi != null) {
        Rectangle r = e.Bounds;
        r.Offset(3, 3);
        string[] s = tlvi.Appointment.Subject.Split(' ');

        for(int i = 0; i < s.Length; i++) {
            using(var foreBrush = new SolidBrush(colorArray[i]))
                e.Cache.DrawString(s[i], tlvi.Appearance.Font, foreBrush,
r, StringFormat.GenericDefault);
            SizeF shift = e.Cache.CalcTextSize(s[i] + " ", tlvi.Appearance.Font);
            r.X += (int)shift.Width;
        }
        e.Handled = true;
    }
}
