I use this for my code and it works:
Vb.net Code:
  1. 'In RadioButtonTip_CheckedChanged event...

  2. If RadioButtonTip.Checked = True Then

  3.    My.Settings.RadBtnTip = 1

  4. Else

  5.    My.Settings.RadBtnTip = 2

  6. End If

  7.  
  8. 'In Form_Load event...

  9. If My.Settings.RadBtnTip = 1 Then

  10.    RadioButtonTip.Checked = True

  11. Else

  12.    RadioButtonTip.Checked = False

  13. End If
