Help with filtering data in a table

Hi,

This is a follow up to the following case:

https://www.experts-exchange.com/questions/27827475/Help-with-creating-multiple-tables-within-a-For-next-Loop.html?anchorAnswerId=38307414#a38307414

when NSN_ID in my  linkssadb file contains the same data (listed below), I receive 4 rows from LinkAID = 1 and LinkAID = 2 in my list box instead of only for data for LinkAID = 1. Is there a way to filter by LinkAID instead of NSN_ID?

I tried changing the filter from  NSN_ID to LinkAID:

MsgBox("keyNsn" & keyNsn)
        Dim _table As DataView = dtMaster.DefaultView
        _table.RowFilter = "LinkAID in (" & keyNsn & ")"
        C1NSN.DataSource = _table
        C1NSN.DataTextField = "NSN"
        C1NSN.DataValueField = "NSN_ID"
        C1NSN.DataBind()

but it does not work.


Linkssadb.xml

<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<Root>
  <LinkA>
    <LinkAID>0</LinkAID>
    <Fuze_ID>0</Fuze_ID>
    <NSN_ID>0</NSN_ID>
  </LinkA>
  <LinkA>
    <LinkAID>1</LinkAID>
    <Fuze_ID>1</Fuze_ID>
    <NSN_ID>1,2</NSN_ID>
  </LinkA>
  <LinkA>
    <LinkAID>2</LinkAID>
    <Fuze_ID>1</Fuze_ID>
    <NSN_ID>1,2</NSN_ID>
  </LinkA>
</Root>
