How to copy/paste TStringGrids cells to/from ClipBoard

Answer:

uses
  Clipbrd;

Copy  

procedure TForm1.Button1Click(Sender: TObject);
var
  S: string;
  GRect: TGridRect;
  C, R: Integer;
begin
  GRect := StringGrid1.Selection;
  S := '';
  for R := GRect.Top to GRect.Bottom do
  begin
    for C := GRect.Left to GRect.Right do
    begin
      if C = GRect.Right then
        S := S + (StringGrid1.Cells[C, R])
      else
        S := S + StringGrid1.Cells[C, R] + #9;
    end;
    S := S + #13#10;
  end;
  ClipBoard.AsText := S;
end;

Paste

procedure TForm1.Button2Click(Sender: TObject);
var
  Grect: TGridRect;
  S, CS, F: string;
  L, R, C: Byte;
begin
  GRect := StringGrid1.Selection;
  L := GRect.Left;
  R := GRect.Top;
  S := ClipBoard.AsText;
  R := R - 1;
  while Pos(#13, S) > 0 do
  begin
    R := R + 1;
    C := L - 1;
    CS := Copy(S, 1, Pos(#13, S));
    while Pos(#9, CS) > 0 do
    begin
      C := C + 1;
      if (C <= StringGrid1.ColCount - 1) and (R <= StringGrid1.RowCount - 1) then
        StringGrid1.Cells[C, R] := Copy(CS, 1, Pos(#9, CS) - 1);
      F := Copy(CS, 1, Pos(#9, CS) - 1);
      Delete(CS, 1, Pos(#9, CS));
    end;
    if (C <= StringGrid1.ColCount - 1) and (R <= StringGrid1.RowCount - 1) then
      StringGrid1.Cells[C + 1, R] := Copy(CS, 1, Pos(#13, CS) - 1);
    Delete(S, 1, Pos(#13, S));
    if Copy(S, 1, 1) = #10 then
      Delete(S, 1, 1);
  end;
end;
