Event Data

The CustomDrawDayOfWeekHeader event's data class is CustomDrawObjectEventArgs. The following 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.

The event data class exposes the following methods:

Method Description
DrawDefault() Renders the element using the default drawing mechanism.


The CustomDrawDayOfWeekHeader event is raised before the Day of Week header is painted. The event parameter’s CustomDrawObjectEventArgs.ObjectInfo property provides the information which is required to paint a header. The return value of this property should be typecast to the DayOfWeekHeader type.

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


This example paints day headers with green gradient color and draws header captions using white color.
