TDrawColumnCellEvent = procedure (Sender: TObject; const Rect: TRect; DataCol: Integer; Column: TColumn; State: TGridDrawState) of object;
property OnDrawColumnCell: TDrawColumnCellEvent;DescriptionWrite an OnDrawColumnCell event handler to provide customized drawing for the data in the cells of the grid. Draw on the cell using the methods of the Canvas property.The Rect parameter indicates the location of the cell on the canvas. The DataCol parameter is the index of the column in the Columns array. The Column parameter is the TColumn object that describes the display attributes and field binding for the cell. The State parameter indicates whether the cell has input focus, whether the cell is selected, and whether the cell is a fixed (non-data) cell such as a column header.An OnDrawColumnCell event handler can call the DefaultDrawColumnCell method to instruct the data-aware grid to write the data value in the cell. The OnDrawColumnCell event handler can augment the DefaultDrawColumnCell method to provide visual indications of selection and focus.If DefaultDrawing is True, the data will already be drawn in the cell before the OnDrawColumnCell event, and the grid draws a focus rectangle around selected cells after the OnDrawColumnCell event.
