TcxGridColumn.OnCustomDrawGroupSummaryCell Event

Fires each time a group summary (that belongs to the currently processed column) is about to be drawn in a group row.

Declaration

property OnCustomDrawGroupSummaryCell: TcxGridGroupSummaryCellCustomDrawEvent read; write;

Remarks

Implement the OnCustomDrawGroupSummaryCell event handler to custom paint the group summary in a group row for a particular column.

Sender specifies the currently processed column.

ACanvas specifies the drawing surface.

ARow specifies the group row in which the group summary is currently drawn.

AColumn specifies the currently processed column.

ASummaryItem specifies the currently drawn group summary.

AViewInfo provides the ViewInfo information for rendering the group summary.

ADone specifies whether default painting is required. Set ADone to True, to prevent default painting.

To manually paint a column’s group summaries located in group footer panels, handle the column’s OnCustomDrawFooterCell event instead.
