TimeCellsControlBase.CustomDrawAppointmentBackground Event

Enables the backgrounds of appointments to be painted in a custom manner.

Namespace:DevExpress.XtraScheduler.Reporting
Assembly:DevExpress.XtraScheduler.v17.1.Reporting.dll

Expanded Syntax

Expanded Event Data

The event handler receives an argument of type CustomDrawObjectEventArgs containing data related to this event.

The following CustomDrawObjectEventArgs properties provide information specific to this event.
Property Description
Bounds Returns the bounding rectangle of the drawing area.
Cache Gets an object which specifies the storage for the pens, fonts and brushes. Use it for custom painting in Scheduler Reports.
Graphics Gets an object used for painting.
Handled Gets or sets whether an event was handled. If it was handled, the default actions are not required.
ObjectInfo Gets information on the painted element.

Expanded Remarks

The CustomDrawAppointmentBackground event is raised before the background of an appointment is printed. The event parameter's CustomDrawObjectEventArgs.ObjectInfo property provides the information on the appointment's background. The return value of this property should be typecast to the AppointmentViewInfo type.

Note

Use the CustomDrawObjectEventArgs.Cache property to paint shapes, write a text and insert images. Do not use the CustomDrawObjectEventArgs.Graphics object in Scheduler Reports.

Set the CustomDrawObjectEventArgs.Handled property to true to prohibit default appointment painting.

Show Me

A complete sample project is available in the DevExpress Code Examples database at http://www.devexpress.com/example=E2758.

This code snippet uses the GraphicsCache object accessible via the CustomDrawObjectEventArgs.Cache property to paint a colored rectangle on the appointment displayed in the DayViewTimeCells visual element of the Scheduler Report.

The CustomDrawAppointmentBackground event is analogous to the SchedulerControl.CustomDrawAppointmentBackground event of the Scheduler control.
