IWAdvRadioGroup Index and value

Delphi Seattle 10

Intraweb 14.3

I have set the items and values of a TTIWAdvRadioGroup.

How do I extract the value of the TTIWAdvRadioGroup's item index after the user has clicked a radio button from that group? 

I have tried using

1) TTIWAdvRadioGroup.Items.ValueFromIndex;
2) ProtDevDeviceRdoGrp.Items.ValueFromIndex[ProtDevDeviceRdoGrp.Itemindex]



You can use the ItemIndex property.

Thank you for your response. I found the value by using radiogroup.Items.Strings[index].
