TcxTreeListCustomReportLink.OnCustomDrawHeaderCell Event

Enables custom painting of the TreeList control column header within the report.

Declaration

property OnCustomDrawHeaderCell: TcxTreeListReportLinkCustomDrawHeaderCellEvent read; write;

Remarks

To implement custom painting of the TreeList control column header within the report you should use the report link OnCustomDrawHeaderCell event and enable custom painting via the SupportedCustomDraw property. Set it to True to enable custom painting and to False to disable it.

To implement custom painting you will need a canvas to paint onto (provided by ACanvas parameter) and painting information provided by the AnItem parameter. Optionally you can access owning report link properties and methods via the Sender parameter and the TreeList column whose header is being painted via the AColumn parameter.

To prevent default drawing of the column header set the ADone parameter to True. By default this parameter is False and default drawing is enabled.
