TCustomGrid.BeforeMoveSelection procedure
Performs actions needed before a selection is moved.
Declaration
procedure BeforeMoveSelection(const DCol: Integer; const DRow: Integer)
; virtualArguments
DCol | Column number where the selection will be stored. |
DRow | Row number where the selection will be stored. |
Description
BeforeMoveSelection is called from the
MoveExtend
method whenever the current grid cursor location is about to change. The
destination column and row are specified in the
DCol and
DRow parameters respectively.
The new location is known to be a valid selectable cell (see 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 the OnBeforeSelection event
handler.
