Namespace: DevExpress.XtraScheduler.Reporting
Assembly: DevExpress.XtraScheduler.v18.1.Reporting.dll
Declaration
Event Data
The CustomDrawDayViewAllDayArea 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 CustomDrawDayViewAllDayArea event is raised before the all-day area is printed. The event parameter’s CustomDrawObjectEventArgs.ObjectInfo property provides the information on the visual element being painted. The return value of this property should be typecast to the DevExpress.XtraScheduler.Drawing.AllDayAreaCell 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 painting. Call the CustomDrawObjectEventArgs.DrawDefault method to perform the default drawing procedure if necessary.
This code snippet illustrates how to change the font and color of the AllDayAreaCell visual elements in the Scheduler Report. The XtraSchedulerReport.GetResourceColorSchema method is used to get colors used to paint areas which belong to different resources.
