Gets a value indicating whether the text in the TextBox control should appear as the default password character.
Returns
true if the text in the TextBox control should appear as the default password character; otherwise, false.
Remarks
The use_system_password_char property has precedence over the password_char property. Whenever the use_system_password_char is set to true, the default system password character is used and any character set by password_char is ignored.
