#857 – Manually Grouping RadioButtons

RadioButtons are normally automatically grouped, based on panel control in which they are located in.  All RadioButtons within a particular panel are considered part of the same group–which means that exactly one RadioButton at a time can be selected.

You can, however, manually control which RadioButtons are considered to be part of a group, regardless of the parent panel in which they are located.  You specify membership in a group using the GroupName property.  GroupName can be set to any string value.  RadioButton instances having the same value for GroupName are considered part of the same group.
