Help with loopingf through GridView and retreiving IDs from xml file or creating new IDs if data does not exist

Hi,

I am using the code below to loop through a listbox to  retreive existing ID(Part A) or create new IDs (Part B).

How do I modify it for a GridView (Windows App, VS 2010)


For x As Integer = 0 To C1NSN.Items.Count - 1

'PartA:
                If CheckForNSNFix.Contains(C1NSN.Items(x).ToString) Then
                    For Each xnLink As Xml.XmlNode In xdNSN.SelectNodes("/Root/NSNTable[NSN='" & C1NSN.Items(x).ToString & "']")
                        NSN_ID = xnLink.SelectSingleNode("NSN_ID").InnerText
                        If NSN_ID <> "" Then
                            CD = NSN_ID
                            If u > 0 Then
                                num1 = num1 & "" & CD & ","
                            Else
                                num1 = CD & ","
                            End If
                            u = u + 1
                        End If
                    Next
                End If
            Next



'Part B:
            'Assign ID to data not already in XML file
            For x As Integer = 0 To C1NSN.Items.Count - 1
                If Not CheckForNSNFix.Contains(C1NSN.Items(x).ToString) Then
                    Dim xNew As XElement = New XElement(xtable)
                    xNew.Add(New XElement(xid, num))
                    xNew.Add(New XElement(curXYZ, C1NSN.Items(x)))
                    MyFix.Root.Add(xNew)
                    MyFix.Save((Application.StartupPath + "\App_Data\" & curXYZ & ".xml"))
                    If uu > 0 Then
                        num2 += num & ","
                    Else
                        num2 = num & ","
                    End If
                    uu = uu + 1
                    num = num + 1
                End If

            Next
            searchIdNSN = num1 & num2

Btw, i assumed that your id is in 1st column, otherwise u need to specify the column as well:
So instead of C1NSN.Items(x).ToString)
Use this:
C1NSN.Items(x)(column-index).ToString()

Or by column name:
C1NSN.Items(x)("Column-name").ToString()
