TimeCellsControlBase.CustomDrawAppointment Event

Enables appointments to be painted in a custom manner.

Namespace:DevExpress.XtraScheduler.Reporting
Assembly:DevExpress.XtraScheduler.v17.2.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 CustomDrawAppointment event is raised before an appointment is printed. The event parameter's CustomDrawObjectEventArgs.ObjectInfo property provides the information about an appointment being painted. 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.

The CustomDrawAppointment event is raised after the AppointmentViewInfoCustomizing event, and should be used if extensive customization is needed. The CustomDrawObjectEventArgs.Cache and CustomDrawObjectEventArgs.Graphics properties of the CustomDrawAppointment event's arguments provide access to objects used for custom painting.

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

The following code sample illustrates the use of the CustomDrawAppointment event to print the appointment's subject and duration using italicized font.

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 containing text and image on the appointment displayed in the DayViewTimeCells visual element of the Scheduler Report.

This event is analogous to the SchedulerControl.CustomDrawAppointment event of the Scheduler control.
