#Remarks

The CustomDrawDayNumberCell event fires when a day cell in the calendar is about to be painted. Handle this event, for instance, if you wish to custom paint particular dates, e.g. by highlighting them.

If you custom paint day cells using the CustomDrawDayNumberCell event, set the Handled parameter to true to prevent the default painting mechanism from being invoked after your CustomDrawDayNumberCell event handler is completed. Otherwise, your painting will be overridden by the default painting mechanism.

Note

You can use drawing methods provided by the e.Graphics object to paint custom information in your CustomDrawDayNumberCell event handler.

Alternatively, you can use drawing methods provided by the e.Cache or e.Style objects. If using the methods provided by the e.Cache or e.Style objects, ensure that the static DevExpress.Utils.Paint.XPaint.ForceGDIPlusPaint method is called on the application startup. Otherwise, you may observe incorrect painting on some operating systems (e.g. Windows 7).
