Wrap User Inputted Text in Textboxes

Given a Textbox (txt1) which spans over 3 lines, when the user types information, the text never goes down to fill the box, instead it continues writing out of the box scope.

I would like for the textbox to wrap the text inputted.
Question is how?

Meaybe I don't understand your question, but do you mean you want your textbox to be multilined? If so, just set the multiline property of it to true. If you mean something else, try to explain some more.

seems clear to me you mean multiline and Irotallic has given you the solution
