Hello,
I can't get this to work. I have both formatted text and plain text (with multiline) and want to display this in the same column. The ultraformattedTextEditor doesn't have any problem with this, it renders both formats correctly.
When setting the column.Style to FormattedText, plain text with line breaks (\r\n) will not be correct.
It seems that a workaround may be the solution here. I'm thinking of using the initialize row and do a string.replace("\r\n", "<br/>").
I'm not clear on whether you tried to replace linefeed/carriagereturn with the <br></br> escape, but that should definitely work.
