//im StringGrid den Zelleninhalt als Hint anzeigen
//Variablen für letzte Zellen Position im Grid
var
  
LastRow, LastCol : Integer;

//Cell Hint anzeigen
procedure TForm1.ShowCellHint(X,Y:Integer);
var
  
ACol, ARow : Integer;
begin
  
//ShowHint auf True setzen
  
If StringGrid.ShowHint = False Then
     
StringGrid.ShowHint := True;
  //Col und Row Position lesen
  
StringGrid.MouseToCell(X, Y, ACol, ARow);
  //wenn im gültigen Bereich zeige Zelleninhalt als Hint
  
If (ACol <> -1) And (ARow <> -1) Then
      
StringGrid.Hint:=StringGrid.Cells[ACol,ARow];
  If (ACol<>LastCol) or (ARow<>LastRow) Then
  begin
    
Application.CancelHint;
    LastCol:=ACol;
    LastRow:=ARow;
  end;
end;

//Example, im MouseMove Ereignis aufrufen
procedure TForm1.StringGridMouseMove(Sender: TObject; Shift: TShiftState; X,
  Y: Integer);
begin
  
ShowCellHint(X,Y);
end;
