   Me.HandleRadioButton(sender, ToolStripDropDownDirection.AboveLeft)
 End Sub

 As Object, e As EventArgs)
 Handles radioButton2.CheckedChanged
   Me.HandleRadioButton(sender, ToolStripDropDownDirection.AboveRight)
 End Sub


Private Sub radioButton3_CheckedChanged(sender
 As Object, e As EventArgs)
 Handles radioButton3.CheckedChanged
   Me.HandleRadioButton(sender, ToolStripDropDownDirection.BelowLeft)
 End Sub
