Hi I want to make the radio group of list disable and enable from the coding. But when i disable the radio group, only one option is disable.For example, let's say the radio group name is "Student" and there are 3 options in this group,say option1: M , option2: F and option3: NWhen i diable the radio group "Student", only the option1: M is disable but others enable. How can i do to disable all these options in the group?If you have any experience about this, please share with me. Thank you.
