So, I have a dynamic text box, which, naturally, being dynamic, changes.

What I would like to figure out is how to tell when the changing text is larger than the textbox holding it.

Of course, just because it is a certain number of characters long doesn't mean it will be larger than the textbox holding it. Twenty of the letter "w" is larger than twenty of the letter "i"

So, is there a way to tell if the textbox isn't large enough to hold its text?

Thanks
