ALV grid display issue from radio buttons

Question

Hello,
I have a radio button group in a selection screen. On select of the first radio button, I display an ALV grid below the radio button group.
On selecting the next one, I want the grid to disappear which isn't happening currently.
Please help.
Thanks and Regards,
Abhijnan
