Text box to show characters in uppercase

Question

How can a text box be enforced to show characters in the uppercase?

Answer 1

TextBox class holds the CharacterCasing property that is used for specifing the case of the content for a text box. This property takes a value from the CharacterCasing enumeration of .NET Framework. Members defined in the CharacterCasing enumeration are Upper, Lower, and Normal. Any one of these enumerations can be selected as a value for the CharacterCasing property of a indicated text box, as shown in the given code:

textBox1.CharacterCasing = CharacterCasing.Upper;
