TcxTreeListCustomReportLink.OnCustomDrawCell Event

Enables custom painting of the TreeList control node cell within the report.

Declaration

property OnCustomDrawCell: TcxTreeListReportLinkCustomDrawCellEvent read; write;

Remarks

To implement custom painting of the TreeList control node cell within the report you should use the report link OnCustomDrawCell 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 the ACanvas parameter) and painting information provided by the AnItem parameter. Optionally you can access the owning report link properties and methods via the Sender parameter and the TreeList column and node (the AColumn and ANode parameters correspondingly) to the painted cell that it belongs.

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