How do you access TCXRadioGroupItem's Checked information

I have a UserForms that have a TCXRadioGroup

and in that i have radio buttons with one defaulted with Checked=True

how do i access all the radio button in that TCXRadioGroup and find out which one is currently checked.

i also try adding name to the individual Radio button inside teh group and tried: UserForms.FormName.rdoButtonName.Checked

and of course that doesnt work

TC does not even recognize the UserForm.FormName.RdoButtonName

I also tried:

UserForm.FormName.GroupName.Properties.ChildControlByName("rdoButtonName") 

and that did not work

i tried by ID and still cannot get teh radiogroupitem to find out if its checked or not.

Thanks.
