Multiline TextBox

I am failing to make a TextBox multiline. The “Multiline” property of the TextBox has made “Yes”, still I am not getting the result. Is there any other property to set with this “Multiline” property. Thanks in advance.

Multiline property is in fact the only thing you need to set, and of course you need to vertically enlarge the textbox. But you do not get vertical scrollbars if that is what you expect.
