Get all rows of alv grid

Hi gurus,

i have the following question for u.

I have to read all rows of alv grid(OOP progamming) without read internal table. At point that i have to read this rows the internal table and table of alv grid didn't match and i cant do refresh.

The only way to read a rows by oop is the method get_selected_rows but i ve to read all rows not only selected ones.

THANKS!!!!
