How to read AVL layout dynamicaly

Hi All there,

I have a requirement that I have to change the ALV layout at runtime by providing some push button.once the push button pressed I have to refresh the layout.

I got the methods get_frontend_fieldcatlog by which I can read the layout and set_frontend_fieldcatlog bothe belongs to class cl_gui_alv_grid.

Can anybody provide me sample code or anyother option to do this.

Regards

Sagar
