xamDataGrid does not update after xml change
posted

I have the following xmlDataProvider specified. After moving an xmlNode to a different position in it parent node, the datagrid tree does not update..

 XmlDataProvider xdp = new XmlDataProvider();

xdp.Document = doc;

xdp.XPath = "perform_select_product_structure_result/product_structures";

Binding bd = new Binding();

bd.Mode = BindingMode.TwoWay;

bd.Source = xdp;

bd.XPath = "product_structure";

theDataGrid.SetBinding(MetrixDataGrid.DataSourceProperty, bd);

private void MoveNodeUp(object sender, RoutedEventArgs e)

{

//MessageBox.Show(e.ToString());

if (theDataGrid.SelectedItems.Records.Count > 0)

{

DataRecord dr = theDataGrid.SelectedItems.Records[0] as DataRecord;if (dr != null)

{

XmlNode row = dr.DataItem as XmlNode;

XmlNode newRow = row.Clone();

XmlNode prev = row.PreviousSibling;

if (prev != null)

{

XmlNode parent = row.ParentNode;

parent.InsertBefore(newRow, prev);

parent.RemoveChild(row);

 

}

}

}
