This Control, derived from TextBoxBase, allows a user to enter and edit simple text strings.

In addition to the base functionality, it allows you to specify the alignment of the text within the control. This TextAlign property respects the right-to-left reading status of the parent. You can also force the CharacterCasing to CharacterCasing.Lower or CharacterCasing.Upper.

The base class provides an AcceptsTab property, which allows the control to receive tab keypresses from the user (and insert them into the text).

TextBox enhances this with an AcceptsReturn property to do the same for the Enter and Return keys.

A PasswordChar can obscure the text displayed for added security. Prior to Windows XP, this was typically *. On Windows XP it is \u25CF (a small round dot).
