Hi I need one solution for TEdit if you have.

I need write inside tedit number and when i go onExit
number has to be formated like this:

100 >>100,00
1000 >> 1.000,00
10000 >>10.000,00
100000>>100.000,00
1000000>>1.000.000,00

and onEnter has to be formated like this
100,00 >>100,00
1.000,00 >> 1000,00
10.000,00 >>10000,00
100.000,00>>100000,00

Use OnEnter and OnExit event of TEdit:

procedure TForm1.Edit1Enter(Sender: TObject);
begin
  TEdit(Sender).Text = FloatToStrF(StrToFloat(TEdit(Sender).Text), ffFixed, 10, 2));
end;

procedure TForm1.Edit1Exit(Sender: TObject);
begin
  TEdit(Sender).Text = FloatToStrF(StrToFloat(TEdit(Sender).Text), ffNumber, 10, 2))
end;
