TextBox.UseSystemPasswordChar Property

Gets or sets a value indicating whether the text in the TextBox control should appear as the default password character.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

public bool UseSystemPasswordChar { get; set; }

Property Value

Type: System.Boolean
true if the text in the TextBox control should appear as the default password character; otherwise, false.

The UseSystemPasswordChar property has precedence over the PasswordChar property. Whenever the UseSystemPasswordChar is set to true, the default system password character is used and any character set by PasswordChar is ignored.

Important noteImportant

When the TextBox is in password mode because PasswordChar, UseSystemPasswordChar, or ReadOnly is true, the TextBox is in restricted mode. In this mode, the ImeMode is disabled, but the current ImeMode is cached so that it can be restored if the TextBox ever becomes unrestricted. Toggling the ReadOnly is a common scenario. The ImeMode is shadowed while the control is in restricted mode. From the designer perspective, the ImeMode value shown is the actual value.
