Hello,

I am loading data from Receiver.xml and Donor.xml files to two combo boxes, when I make a change to the “Name” element in Receiver and Donor from the combox boxes, how do I save the modified “Name” element. Below is the code I am using to load the combo boxes, the DropDownStyle property was set to Simple to make it look like a Textbox.
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        DonorStream.Load(Application.StartupPath & "/donor.xml") 'My.Resources.Donor)
        RecStream.Load(Application.StartupPath & "/receiver.xml") 'My.Resources.Receiver)
        LinkStream.Load(Application.StartupPath & "/link.xml") 'My.Resources.Link)
        ReadLink()
End Sub

Public Sub ReadLink()
        FillCombos()
        btnNext.PerformClick()
    End Sub

    Public Sub FillCombos()
        Dim RecName As XmlNodeList = RecStream.SelectNodes("Root/Receiver")
        Dim DonorName As XmlNodeList = DonorStream.SelectNodes("Root/Donor")

        Dim donorlst As New DataTable()
        donorlst.Columns.Add("ID")
        donorlst.Columns.Add("Name")
        Dim reclst As New DataTable
        reclst.Columns.Add("ID")
        reclst.Columns.Add("Name")

        For Each node As XmlNode In RecName
            reclst.Rows.Add(New Object() {node.ChildNodes(0).InnerText, node.ChildNodes(1).InnerText})
        Next

        For Each node As XmlNode In DonorName
            donorlst.Rows.Add(New Object() {node.ChildNodes(0).InnerText, node.ChildNodes(1).InnerText})
        Next

        CmbDonor.DataSource = donorlst
        CmbDonor.DisplayMember = "Name"
        CmbDonor.ValueMember = "ID"

        CmbRec.DataSource = reclst
        CmbRec.DisplayMember = "Name"
        CmbRec.ValueMember = "ID"

By the way, I'm curently 6 hous ahead of US EST, my reply might be during odd hours, These questions may seem similar in the future because I will also need to develop web version with the same features using ASP.NET.

Thanks,
