A multi-lne text box uses the HTML textarea element, and the HTML specification does not allow for any restrictions in the amount of data which may be input by the user. Because of this there is nothing the framework can insert into the HTML document to restrict user input. There is no way to turn off the scroll bar, so you cannot use the numbers of lines and rows to restrict user input.

You can restrict the column size in the data dictionary, but this cannot be checked in the server-side code until after the form has been posted.
