How to create fixed container ALV (OO ALV) that is with no manual resizing?

Hi Experts,

I have used OO ALV. I have used splitter to create two container one above the other.

But user can manually resize the ALV containers. How can we prevent manual resizing?

I have used below code. But it does not help. User can still resize.

CALL METHOD splitter->set_row_height
EXPORTING
id = 2
height = 8..

Please help.

Thanks

Gopal
