XML and Datagridview

Hello, I hope someone can give me some help.
I have a datagridview (Unbound), wich calculate several numbers, and I use this following code to save 5 of the columns to a XML file.

My problem is that I would like to load this file back to my datagridview, and onlu to the same columns, without changing the rest of the datagridview.

Code used to create XML file:

Code:

---

        Dim gridtable As DataTable = New DataTable("WaypointLeg")
        Dim gridtable_collumn1 As DataColumn = New DataColumn("column1")
        Dim gridtable_collumn11 As DataColumn = New DataColumn("column11")
        Dim gridtable_collumn18 As DataColumn = New DataColumn("column18")
        Dim gridtable_collumn19 As DataColumn = New DataColumn("column19")
        Dim gridtable_collumn20 As DataColumn = New DataColumn("column20")
        Dim name As String
        name = IDTextBox.Text
        gridtable.Columns.Add(gridtable_collumn1)
        gridtable.Columns.Add(gridtable_collumn11)
        gridtable.Columns.Add(gridtable_collumn18)
        gridtable.Columns.Add(gridtable_collumn19)
        gridtable.Columns.Add(gridtable_collumn20)
        Dim gridrow As DataGridViewRow
        Dim table_row As DataRow
        For Each gridrow In DataGridView1.Rows
            table_row = gridtable.NewRow
            table_row("column1") = gridrow.Cells("column1").Value
            table_row("column11") = gridrow.Cells("column11").Value
            table_row("column18") = gridrow.Cells("column18").Value
            table_row("column19") = gridrow.Cells("column19").Value
            table_row("column20") = gridrow.Cells("column20").Value
            gridtable.Rows.Add(table_row)
            gridtable.WriteXml(Application.StartupPath & "\Data\" & name & ".xml")
        Next gridrow

I have tried with the following code but when I use this, the data from my XML file appear at the end of my datagridview (Adding 5 more columns to the end). I would like to "update" the same columns...

Code I use to Load XML file:

Code:

---

Dim name As String
        name = IDTextBox.Text
        Dim xmlFile As XmlReader
        xmlFile = XmlReader.Create(Application.StartupPath & "\Data\" & Name & ".xml", New XmlReaderSettings())
        Dim ds As New DataSet
        ds.ReadXml(xmlFile)
        DataGridView1.DataSource = ds.Tables(0)

---

Anyone knows how I can load my XML file, and only update certain columns in my datagridview and not add 5 more columns to my datagridview?

Is there a way to load the XML data to my datagridview without binding the datagridview to the XML file?

I mean without the use of the:

Code:

---

DataGridView1.DataSource = ds.Tables(0)

---

Try setting AutoGenerateColumns property of the DataGridView to False as shown below.

Code:

---

DataGridView1.AutoGenerateColumns = False
Dim name As String
name = IDTextBox.Text
Dim xmlFile As XmlReader
xmlFile = XmlReader.Create(Application.StartupPath & "\Data\" & Name & ".xml", New XmlReaderSettings())
Dim ds As New DataSet
ds.ReadXml(xmlFile)
DataGridView1.DataSource = ds.Tables(0)

Thanks for your suggestion, I tried it out, but it does not do the whole job.
It does not add more columns, but it does not add my XML data to my datagridview. The only thing that happens is that I get the correct amount of rows in my datagridview, but unfortunate all rows are empty, and I have no data in my datagridview.

Hello,
is there anyone that may have som ideas for how I can solve this problem?
