title: Check if ListView item selected
body: <p>I wanna make my Button's IsEnabled property to check if ListView has a selection.
  Is there any way to check if any ListView item is selected using only XAML?
  Something like:</p>
  
  <pre><code>&lt;Button Content="Remove" Command="{Binding RemoveConditionCommand}"
                  CommandParameter="{Binding ElementName=conditionsListView, Path=SelectedItem}"
                  IsEnabled="{Binding ElementName=conditionsListView, Path=IsSelected}"
                  /&gt;
  </code></pre>
