CharacterCasing Enumeration

Specifies the case of characters in a TextBox control.

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

public enum CharacterCasing

Member nameDescription
LowerConverts all characters to lowercase.
NormalThe case of characters is left unchanged.
UpperConverts all characters to uppercase.

Use the members of this enumeration to set the value of the CharacterCasing property of the TextBox control.

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.

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;
 }
