{ Question: How do I change the cell font color in a TDBgrid I only want to change the individual cell that is clicked on! (while in the edit mode) Answer: Since it is the InplaceEditor control that is displayed when the cell is in edit mode you have to change this controls Color. Getting at it is a bit ugly since the InplaceEditor property of TCustomGrid (which TDBGrid inherits) is protected and the Color property of TCustomMaskedit (from which TInplaceEditor inherits) is also protected. The following works for a TStrinGrid. I used the grids OnGetEditMask event here to have a place where the inplace editor is guaranteed to exist. For a TDBGrid you could probably use OnColEnter. Frage: Wie дndere ich die Farbe der aktuellen Zelle eines Stringgrids oder TDBGrids ? Antwort: Der InplaceEditor wird angezeit, wenn eine Zelle im Editiermodus ist. Es muss also dessen Farbe geдndert werden. Dies kann ьber eine "Cracker"-Klasse erreicht werden. } typeTForm1 = class
(TForm) {...} procedure
StringGrid1GetEditMask(Sender: TObject; ACol, ARow: Integer; var
Value: string
); procedure
DBGrid1ColEnter(Sender: TObject); end
; {...} uses
Mask; type
TGridCracker = class
(TCustomGrid); TEditorCracker = class
(TCustomMaskEdit); procedure
TForm1.StringGrid1GetEditMask(Sender: TObject; ACol, ARow: Integer; var
Value: String
); var
editor: TEditorCracker; begin
editor := TEditorCracker(TGridCracker(Sender).InplaceEditor); if
Assigned(editor) then
editor.Color := clYellow; end
; procedure
TForm1.DBGrid1ColEnter(Sender: TObject); var
editor: TEditorCracker; begin
editor := TGridCracker(TGridCracker(Sender).InplaceEditor); if
Assigned(editor) then
editor.Color := clGreen; end
;
