Grouping of Dynamically create radio button in Dynamically created Panels

For this purpose, use the control System.Windows.Forms.GroupBox, please see http://msdn.microsoft.com/en-us/library/system.windows.forms.groupbox.aspx[^].

During dynamic creation, add all mutually exclusive choices by RadioButton as children of the same instance of GroupBox using Control.Controls.Add or by setting value of the property Control.Parent of each RadioButton to the same instance of GroupBox, see:
http://msdn.microsoft.com/en-us/library/system.windows.forms.radiobutton.aspx[^].

Doing it dynamically is not harder than what you already done.

[EDIT]

By the way, you could do exact same thing using Panel as a container for your radio buttons. The only reason to use an instance of the GroupBox is to give a common text label to the group (the property GroupBox.Text). You can also use "&" prefix to one character of a label text (as you would do with usual labels (Label class); then it will serve as a hot key for a whole group.
