XAML Snippet (Added from Solution 1)

XML

<DataGrid x:Name="DG" ItemsSource="{Binding model.Element}" Grid.Column="2" Grid.Row="3" AutoGenerateColumns="False"  CanUserAddRows="True" CanUserDeleteRows="True" SelectedItem="{Binding model.SelectedParameter, Mode=TwoWay, Converter={StaticResource ParameterConverter}}" >

What I have tried:

C#

XmlReader reader = XmlReader.Create(ofd.FileName);
reader.ReadToDescendant("Element");
XmlSerializer serializer = new XmlSerializer(typeof(Element));
Element element = new Element();
element = (Element)serializer.Deserialize(reader.ReadSubtree());
model.Element.Add(element);

Can you also add the XML that is not working? (If the XML you are showing is in fact working>

There could be more than dozens of possibilites why it is not working. "Button with Binding/Command" To call your XmlReader Method? Also the binding to your DataGrid would be interesting.

if your model is filled up correctly with your xml values, you may read this CP article that explains how to bind a WPF Datagrid to a model.
