How to Export DGV to XML

Hi Everybody

i have a datagridview in VB.NET which is filled with an XML file this way:

Expand|Select|Wrap|Line Numbers
  1. Dim xmlDataDoc As New XmlDataDocument
  2. Dim ds As New DataSet("Book Dataset")
  3.  
  4. xmlDataDoc.DataSet.ReadXml("D:\books.xml")
  5. ds = xmlDataDoc.DataSet
  6. DataGridView1.DataSource = ds.DefaultViewManager
  7. DataGridView1.DataMember = "Book"
  8.  
When i make Changes in the DGV, i want wo save them back to the
XML-File. But i don't know how!

i tried:

Expand|Select|Wrap|Line Numbers
  1. Dim DS As DataSet
  2. ' --- DataSet erzeugen
  3. DS = New System.Data.DataSet()
  4. DS = DataGridView1.DataSource
  5. DS.WriteXml("D:\ddd.xml", XmlWriteMode.WriteSchema)
  6.  
what is wrong? the problem is: i cant make a DataSet out of the dgv with
DS = DataGridView1.DataSource.
What else can i do?

Thanks
MIchael
