Event Data

The CustomDrawWeekViewTopLeftCorner 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.

Remarks

The CustomDrawWeekViewTopLeftCorner event is raised by the WeekView, MonthView and the TimelineView when they are grouped by dates (SchedulerViewBase.GroupType is set to the SchedulerGroupType.Date). This event occurs before the top left corner of the view is painted.

You can call the CustomDrawObjectEventArgs.DrawDefault method to perform default painting before applying custom draw.

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

Example

This example inserts text in the top left corner of the WeekView view and its descendants - the MonthView and the TimelineView views.
