Keterangan

AutoCompleteSource tidak berfungsi pada kontrol multibaris TextBox .

Saat font diubah, indentasi apa pun yang telah Anda tentukan tidak muncul. Untuk mendapatkan indentasi, atur Multiline ke true dan ambil alih WM_SETFONT tanpa memanggil kelas dasar sehingga SETMARGINS tidak dipanggil.
