Visual basic ComboBox.SelectedIndex

Question

I develop a vb.net application, and I'm having troubles with comboboxes.

I have this to know when the selected item on my combobox is changed :

Private Sub ComboBoxSite_SelectedIndexChanged(sender As Object, e As EventArgs) Handles ComboBoxSite.SelectedIndexChanged
    If (ComboBoxSite.SelectedIndex <> 0) Then 'If it is not the default value
        Console.WriteLine("ActionListenerIndex = {0}", ComboBoxSite.SelectedIndex) 'To debug
        RequestAccesv2(0)
    End If
End Sub

And the RequestAccessv2() function

Private Sub RequestAccesv2(taille As Integer)
    initBoxesLocation() 'A function that clear/refill 4 comboBoxes
    Console.WriteLine("SELECTED INDEX SITE : {0}", ComboBoxSite.SelectedIndex)
        Select Case taille
            Case 0 ..... 'Some database treatment

End Sub

And there is the result on the output, when the second function is called, I don't have the same selectedIndex :

ActionListenerIndex = 2
SELECTED INDEX SITE : -1 'Does it means thas nothing is selected ?

Have you already had/solved this problem ?

Thanks for your answers !

Indeed Steve and A Friend the problem was coming from the function initBoxesLocation. In this fuction I was clearing 4 comboboxes, then I added 1 item on each.

I didn't realy understand where does the problem comes.

edit : Yes of course, once my comboboxes refiled I didn't selected an item again so there is the problem.

Private Sub initBoxesLocation()
    Console.WriteLine("initialisation entete")
    initBoxEnteteSite()
    initBoxEnteteBuilding()
    initBoxEnteteModule()
    initBoxEnteteRoom()
End Sub

I split the initBoxesLocation() function, by calling one or an other reset function depending on the combobox changed, I needed actually not to call them all.

Now it works !
