SelectionChangeCommitted() Event not working?

I have several ComboBox controls on my a Form. Each of these are within a separate panel control (5 panels, 1 combobox per panel).

I'm using the SelectionChangeCommitted() Event for each of these comboboxes. My problem is that when I select a value, it executes the event but the value is nothing. I then select the same value again and then it has a value and it executes the way it is suppose to. Why is it taking 2 times to get a value? Here is just one of the Event Procedures below. I just use one because the rest are just like it...with the exception of the field name.

        Private Sub cmbTApprover_SelectionChangeCommitted(sender As Object, e As EventArgs) Handles cmbTApprover.SelectionChangeCommitted
        Try
                strErr = ""

                If cmbTApprover.Text.Length > 0 Then
                    ptLoc = cmbTApprover.PointToScreen(New Point(0, 0))
                    ptLoc.Y += cmbTApprover.Height + 5

                    gstrApprover = cmbTApprover.Text

                    If GetApproverPassword() Then
                        btnUpdate.Enabled = True
                    End If
                End If

        Catch ex As Exception
            strErr = gfrmID & "/cmbTApprover_SelectionChangeCommitted() - " & ex.Message & ",E"
        End Try

        ProcessMessages(Me, sbr, strErr)
    End Sub
