I've tried doing it with exporting the solution and changes the XML code and then importing it again. as you can see in the image two bars after 'Do You Want to' column. But when I open this grid in Unified client interface it is still visible.
like in this grid.if 'isAllowOverride' is True I want to make 'Do you want to' be editable. But 'isAllowOverride' has to be invisible from User end.
