protected procedure TCustomGrid.BeforeMoveSelection( |
const DCol: Integer; |
const DRow: Integer |
); virtual; |
This method is called from TCustomGrid.MoveExtend method whenever the current grid cursor location is about to change. The destination column and row are specified in DCol and DRow parameters respectively. The new location is known to be a valid selectable cell (see TCustomGrid.SelectCell ), and is given in absolute cell coordinates. At this point the current grid location has not changed and can be retrieved with Col and Row properties. The purpose of this method is to call event handler OnBeforeSelection.
