Question

With VCL, we had a TRadioGroup class with an Items property you could modify at design time. With Firemonkey, we only have the TRadioButton class.

From what I understand, if you add objects of type TRadioButton as children to other container objects (e.g. TPanel, TGroupBox), these containers will effectively act like the VCL TRadioGroup objects.

However, these individual radio buttons seem to behave as if they are all children of the same parent. If you select a radio button in group A, and then select a radio button in group B, the radio button in group A is deselected.

How can I get radio buttons in one container object to not deselect radio buttons in other container objects?

Here’s an example of my form design:

Answer 1

Set the GroupName properties of the buttons. Radio buttons with the same group name will act as a separate group.
