title: Make ListView Item Selected Form ItemSource
body: <p>I have a ListView like this</p>
  
  <pre><code>&lt;ListView x:Name="lview" SelectionMode="Multiple"&gt;
      &lt;ListView.ItemTemplate&gt;
          &lt;DataTemplate&gt;
              &lt;TextBlock Text="{Binding Name, Mode=OneWay}" /&gt;
          &lt;/DataTemplate&gt;
      &lt;/ListView.ItemTemplate&gt;
  &lt;/ListView&gt;
  </code></pre>
  
  <p>I am binding data to this Listview like this</p>
  
  <pre><code>public MainPage()
  {
      this.InitializeComponent();
      ObservableCollection&lt;OptionItem&gt; io = new ObservableCollection&lt;OptionItem&gt;();
      io.Add(new OptionItem { Name = "11111111111", IsSelected=false });
      io.Add(new OptionItem { Name = "22222222222", IsSelected=true });
      io.Add(new OptionItem { Name = "33333333333", IsSelected=true });
      io.Add(new OptionItem { Name = "44444444444",IsSelected=false });
  
      lview.ItemsSource = io;
  }   
  </code></pre>
  
  <p>Now you can see inside my Model, I have a Property called <code>IsSelected</code>. How can I bind this to the listView, so that the Items selected in the <code>ItemsSource</code> comes as selected in ListView?</p>
