How to make use of class cl_gui_alv_grid

Hi Expert,

I have an ALV which has been developed using Object Oriented Programming. Now i need to enable the push button, that will enable the users to select any row they want. i have investigated and found the i need to update the field SEL_MODE with the value 'A' in order to have this functionality working.

i have tried with my obect to call the method set_table_for_first_display, but i'm getting an errror message saying that it is protected or unknown..

Can anyone let me know on how to enable this functionality?

Thank you very much.
