Display characters in uppercase in textbox

Question

How one can implement the text box to display characters in the uppercase?

Answer 1

TextBox class has a CharacterCasing property that is used to identify case of content for the text box. This property allows the value from a CharacterCasing enumeration of the .NET Framework. Members specified in a CharacterCasing enumeration are Normal, Lower and Upper. We can choose any one of the enumerations as the value for a CharacterCasing property of the particular text box, like: 

textBox1.CharacterCasing = CharacterCasing.Upper;
