Tks Sergey :)

The situation is:
I have a edit region control, I send it lines of text from textbox control,
when the user press enter key. The edit region control is read only, when I send the line I would like to show the bottom of edit region, the last line introduced.
After enter key, only I can c the top of edit region control.

I hope that u can help me.
:) tks
