| System.Web.UI.HtmlControls (system.web.dll) | class |
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).
