New Post: Can't figure out how to use PropertyGrid

<ListView Name="ProductsList" 
                      Grid.Column="0"
                      ItemsSource="{Binding Products}">
                <ListView.View>
                    <GridView>
                        <GridViewColumn DisplayMemberBinding="{Binding Name}" Header="Name"/>
                    </GridView>
                </ListView.View>
            </ListView>
            <GridSplitter Width="5"/>
            <xctk:PropertyGrid Name="ProductPropertyGrid" Grid.Column="1" DataContext="{Binding ElementName=ProductsList, Path=SelectedItem}" AutoGenerateProperties="True"/>
