TextBox.PasswordChar Property

Gets or sets the character used to mask characters of a password in a single-line TextBox control.

[Visual Basic]
Public Property PasswordChar As Char
[C#]
public char PasswordChar {get; set;}
[C++]
public: __property __wchar_t get_PasswordChar();
public: __property void set_PasswordChar(__wchar_t);
[JScript]
public function get PasswordChar() : Char;
public function set PasswordChar(Char);

Property Value

The character used to mask characters entered in a single-line TextBox control. Set the value of this property to 0 (character value) if you do not want the control to mask characters as they are typed. Equals 0 (character value) by default.

Remarks

If the Multiline property is set to true, setting the PasswordChar property has no visual effect. When the PasswordChar property is set to true, cut, copy, and paste actions in the control using the keyboard are not allowed, regardless of whether the Multiline property is set to true or false.

Note[note] On Japanese operating systems, the PasswordChar applies regardless of whether the Multiline property is true or false. On other operating systems, the PasswordChar applies only when Multiline is false.

Example

The following example creates a TextBox control that is used to accept a password. This example uses the CharacterCasing property to change all characters typed to uppercase and the MaxLength property to restrict the password length to eight characters. This example also uses the TextAlign property to center the password in the TextBox control.

[Visual Basic] 
Public Sub CreateMyPasswordTextBox()
    ' Create an instance of the TextBox control.
    Dim textBox1 As New TextBox()
    ' Set the maximum length of text in the control to eight.
    textBox1.MaxLength = 8
    ' Assign the asterisk to be the password character.
    textBox1.PasswordChar = "*"c
    ' Change all text entered to be lowercase.
    textBox1.CharacterCasing = CharacterCasing.Lower
    ' Align the text in the center of the TextBox control.
    textBox1.TextAlign = HorizontalAlignment.Center
End Sub


[C#] 
public void CreateMyPasswordTextBox()
 {
    // Create an instance of the TextBox control.
    TextBox textBox1 = new TextBox();
    // Set the maximum length of text in the control to eight.
    textBox1.MaxLength = 8;
    // Assign the asterisk to be the password character.
    textBox1.PasswordChar = '*';
    // Change all text entered to be lowercase.
    textBox1.CharacterCasing = CharacterCasing.Lower;
    // Align the text in the center of the TextBox control.
    textBox1.TextAlign = HorizontalAlignment.Center;
 }
 

[C++] 
public:
void CreateMyPasswordTextBox()
 {
    // Create an instance of the TextBox control.
    TextBox* textBox1 = new TextBox();
    // Set the maximum length of text in the control to eight.
    textBox1->MaxLength = 8;
    // Assign the asterisk to be the password character.
    textBox1->PasswordChar = '*';
    // Change all text entered to be lowercase.
    textBox1->CharacterCasing = CharacterCasing::Lower;
    // Align the text in the center of the TextBox control.
    textBox1->TextAlign = HorizontalAlignment::Center;
 }
 

[JScript] 
public function CreateMyPasswordTextBox()
 {
    // Create an instance of the TextBox control.
    textBox1 = new TextBox();
    // Set the maximum length of text in the control to eight.
    textBox1.MaxLength = 8;
    // Assign the asterisk to be the password character.
    textBox1.PasswordChar = '*';
    // Change all text entered to be lowercase.
    textBox1.CharacterCasing = CharacterCasing.Lower;
    // Align the text in the center of the TextBox control.
    textBox1.TextAlign = HorizontalAlignment.Center;
 }
