Remarks

Handle the OnCustomDrawLevelCaption event handler to perform custom drawing of the level captions in a report.

Parameter	Description
Sender	Represents the report link that renders the report
ACanvas	A TCanvas instance for drawing the Level caption on the report.
AView	The view that contains the data being printed.
AnItem	Specifies the properties of the printed cell.
ADone	Determines whether custom drawing has finished and that default painting is not required.

Set the SupportedCustomDraw property to False to disable custom drawing. This will improve application performance slightly as resources don’t have to be created to support custom draw handlers.
