This class represents the HTML <textarea> tag, which allows the user to enter multiple lines of text. Text entered in this control is provided in the Value property. You can specify the size of the text box by using the Rows property and the Cols property (the character width). Both default to -1 to indicate that a standard size will be used. You can also react to the ServerChange event, which will fire only after a postback is triggered (for example, when a user clicks a submit button).
