Checked Change Fires two events? (Resolved)

That's right . I've just figured it out ! . To avoid a lot of hassle , use Click event .

Private Sub radQ1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles radQ1.Click, radQ2.Click, radQ3.Click, radQ4.Click
 
        Select Case DirectCast(sender, RadioButton).Name
            Case "radQ1"
                MsgBox("You just changed the radio button.")
                'FillDataGrid()
            Case "radQ2"
                MsgBox("You just changed the radio button.")
                'FillDataGrid()
            Case "radQ3"
                MsgBox("You just changed the radio button.")
                'FillDataGrid()
            Case "radQ4"
                MsgBox("You just changed the radio button.")
                'FillDataGrid()
        End Select
 
    End Sub
