Jose,
This is not the exact answer, however maybe you can use it for your problem,
I made it some minutes ago for another question in the language.vb
newsgroup. For the sample with the states in a listbox and using that in an
object array are I thought thousands of samples on Internet.
When this sample beneath does not fit, remember than that you have to cast
the object in the selected arrayitem to datarowview to use it.

\\\needs a form with 2 listboxes and one textbox
Private Sub Form1_Load(ByVal sender As Object, _
ByVal e As System.EventArgs) Handles MyBase.Load
Dim countries() As String = {"US", "EU"}
ListBox1.Items.AddRange(countries)
Dim table As New DataTable("Sample")
CreateTable(table)
Dim dv As New DataView(table)
ListBox2.DataSource = dv
dv.Sort = "Name"
ListBox2.DisplayMember = "Name"
TextBox1.DataBindings.Add(New Binding("Text", dv, "Id"))
End Sub
Private Sub ListBox1_SelectedIndexChanged(ByVal sender _
As Object, ByVal e As System.EventArgs) Handles
ListBox1.SelectedIndexChanged
DirectCast(ListBox2.DataSource, DataView).RowFilter = _
"Country = '" & ListBox1.SelectedItem.ToString & "'"
End Sub
Private Sub CreateTable(ByVal Table As DataTable)
Table.Columns.Add("Id")
Table.Columns.Add("Name")
Table.Columns.Add("Country")
For i As Integer = 0 To 7
Dim dr As DataRow = Table.NewRow
dr(0) = i.ToString
Table.Rows.Add(dr)
Next
Table.Rows(0)(1) = "Herfried K. Wagner"
Table.Rows(1)(1) = "Armin Zingler"
Table.Rows(2)(1) = "Ken Tucker"
Table.Rows(3)(1) = "CJ Taylor"
Table.Rows(4)(1) = "Jay B Harlow"
Table.Rows(5)(1) = "Terry Burns"
