adj. Consisting of multiple lines.

"With the textbox set as 'multiline', there must be some way to indicate a NewLine is being requested, and that is almost always the ENTER key ... so you probably won't find a workaround unless you put some javascript in place to do a postback of the page when the enterkey is detected ... but then that would make it very difficult to make a new line in your multiline textbox"
