Hello,


I tested the control within the User control web part and it works fine.

In your case: if you press Enter, does it create a new line in the textbox but not in the output, or it does not create a new line within the input?

I only needed to convert \n to any other "end line" character when I wanted to display multiline output by HTML, for example:

(tb3.Text).Replace("\n", "<br />")


Best regards,
Helena Grulichova
