Line 453: Dim ParentTableView As New
DataView(DsSell ers1.Tables("SE LLERS"))
Line 454: Dim CurrentRowView As DataRowView =
ParentTableView .Item(Me.cboSel lers.SelectedVa lue)

MG,

When you want to use the index on a combobox has to be related to the
datasource.

(However probably is your problem that you use the selectedvalue instead of
the selectedindex, probably something in your eyes that does not allow you
to see that)

:-)
