Hi Cam,

There is no built-in limit on the control itself. So in theory, it should be able to handle an unlimited amount of text.

Of course, in practice, this is limited by the amount of memory on the machine and the efficiency of the FormattedTextEditor control itself.

The control was originally designed as a label and then updated to provide editing capabilities. So it really was not designed to deal with large amounts of text. So I doubt very much that the control would be useful with 10k of text in it, or anwyhere near that.

Handling large text is a feature a lot of users have requested and it's something we are hoping to add in the near future.
