ALV Row Counter

Hi All - I have an ALV table that display 15 row; if the ALV has more than 15 records let's say 1000 row on the vertical scroll bar will display row 20 of 1000 or 31 of 1000 (feature that ALV default for the user)

I want to display that same logic but in a text out of the ALV, how I can read all the rows of the ALV and display...i.e. "856 records displaying" and also if the user select row 754 it should say "you have selected row 754 out of 1000 records"

Is this possible?

Thanks!
