This class represents the text box web control and provides properties to configure text wrapping, the maximum accepted length, and the size in fixed character widths and row-heights (Columns and Rows). This class also includes a single event, TextChanged, which will fire only when the text box loses focus and a post back is generated.
The text box is abstracted away from any specific HTML element. Depending on your settings, ASP.NET will use the appropriate <input type="text">, <input type="password">, or <textarea> HTML tag.
