Question:
Is it possible to access a grid row or column by name?
Answer:
The following example presents two functions: GetGridColumnByName()
and GetGridRowByName() that return the given column or row that
contains the specified caption.
procedure TForm1.FormCreate(Sender: TObject);
begin
StringGrid1.Rows[1].Strings[0] := 'This Row';
StringGrid1.Cols[1].Strings[0] := 'This Column';
end;
function GetGridColumnByName(Grid : TStringGrid;
ColName : string): integer;
var
i : integer;
begin
for i := 0 to Grid.ColCount - 1 do
if Grid.Rows[0].Strings[i] = ColName then begin
Result := i;
exit;
end;
Result := -1;
end;
function GetGridRowByName(Grid : TStringGrid;
RowName : string): integer;
var
i : integer;
begin
for i := 0 to Grid.RowCount - 1 do
if Grid.Cols[0].Strings[i] = RowName then begin
Result := i;
exit;
end;
Result := -1;
end;
procedure TForm1.Button1Click(Sender: TObject);
var
Column : integer;
Row : integer;
begin
Column := GetGridColumnByName(StringGrid1, 'This Column');
if Column = -1 then
ShowMessage('Column not found') else
ShowMessage('Column found at ' + IntToStr(Column));
Row := GetGridRowByName(StringGrid1, 'This Row');
if Row = -1 then
ShowMessage('Row not found') else
ShowMessage('Row found at ' + IntToStr(Row));
end;
