How to display row number in TStringGrid?

Question

How do I create a column in a TStringGrid in FireMonkey that displays the row number?

If it's by using a LiveBinding, I can't figure out how.

Answer 1

Your forms/grids OnGetValue event handler is passed the row as one of it's parameters. Simply verify the column is the one you want and return the row number.

function Form1.Grid1GetValue(const Row, Col: Integer): TValue;
begin
  if Col = 0 then
    Result := TValue.From<Integer>(Row);
end;
