Creating a group of radio buttons

Question

Hi. Thanks for your help. I am a newbie to the Windows Forms. 

 

I want to creat a group of radio buttons such that when I click one of them, any other which may be already checked, it is unchecked. I am using Windows Form App.  

 

I saw an example in XML, however, it seems that with the form that I am implementing the radio buttons, there is not a "companion" XML screen as it is when designing something in   WPF.

 

I appreciate any help you can provide.
