Checked Change Fires two events? (Resolved)

[BukHix]

This codes seems to fire two events, which I guess is because there is an event fired when I leave one radio button and then another event fired when I enter a new radio button.

Private Sub radQ1_CheckedChanged(ByVal sender As Object, _
        ByVal e As System.EventArgs) Handles _
        radQ1.CheckedChanged, radQ2.CheckedChanged, _
        radQ3.CheckedChanged, radQ4.CheckedChanged
 
        MsgBox("You just changed the radio button.", _
            MsgBoxStyle.OKOnly, "Event Fired")
        FillDataGrid()
 
    End Sub

Is there a way to do this that will fire only one event? Or is there a better way to do what I am doing, which is basically filling a datagrid based on which quarter the user chooses (4 radio buttons).
