Not absolutely so. It scroll the caret, not the text. And yes, when the caret is in bottom of the TextBox, text will scroll. But if i need to scroll text up, i'll have to move caret from the bottom to the top. And the caret's blinking is so annoying
But i want to make something like...err...text reader, where the text will scroll line-by-line by pressing HardwareKey. I use TextBox instead of something different because i need to copy\paste text.
