Well, you *could* do it by checking the formattedWidth of the field against the width of the field, and if it's larger, delete characters from the front of the text until the formattedWidth <= the width. But then you'd have to keep track of what the user entered in a custom property or variable. I noticed you say that your field is locked - if it was unlocked, then LC would just manage the hScroll of the field; I'm assuming you can't leave your field unlocked for some reason, so you can use use the same formattedWidth vs. width test and then set the hScroll of the field manually. But you mentioned "without relying on horizontal scroll"… is there a reason you don't want to use the hScroll? Ken Ray Sons of Thunder Software, Inc.
