I have this dialog

See the red Box
the problem is that the user can only enter the prices in a single column among those inserted in the red box. how do i block the entry.
i.e. if for example the user presses a button in the sixth column he cannot then press the prices in the seventh / eighth / ninth / tenth column
How I can make to Block a column ( from 6 to 10) if the user press a button on six/ten column?
