TdxGridReportLink.OnCustomDrawFooterCell Event

Occurs when the footer panel for a cell in the report is going to be drawn.

Declaration

property OnCustomDrawFooterCell: TdxGridReportLinkCustomDrawFooterCellEvent read; write;

Remarks

Handle the OnCustomDrawFooterCell event handler to perform custom drawing of a cell within the footer panel of a report.

Parameter	Description
Sender	Represents the report link that renders the report
ACanvas	A TCanvas instance for drawing the footer cell on the report.
AView	The view that contains the data being printed.
ARecord	The grid record being printed.
AColumn	The column being printed.
ALevel	Identifies the nesting level of the grouping row for which the footer cell is being painted.
AnItem	Specifies the properties of the printed cell.
ADone	Determines whether custom drawing has finished and that default painting is not required.

Custom drawing can be disabled by setting the SupportedCustomDraw property to False. This will improve application performance slightly as resources don’t have to be created to support custom draw handlers.

Note

To implement custom drawing of the footer panel, make sure that the footer panel exists and isn’t empty; otherwise, custom drawing will not be performed.
