Comentários

AutoCompleteSource Não funciona em controles de várias linhas TextBox .AutoCompleteSource does not work on multiline TextBox controls.

Quando a fonte for alterada, qualquer recuo definido não será exibido.When the font is changed, any indentation that you have defined does not appear. Para obter recuo, defina Multiline para true e substitua WM_SETFONT sem chamar a classe base para que SetMargins não seja chamado.To get indentation, set Multiline to true and override WM_SETFONT without calling the base class so that SETMARGINS is not called.
