title: Correct way to use a Interaction Trigger on SelectionChanged Event
body: <p>I have a command wired to the event such that it does fire, but what I get in the CommandParameter is the previously selected item, or maybe it's the selected item before the SelectionChanged completes.</p>
  
  <p>Either way, not sure what to change to get the newly selected item from the event.</p>
  
  <pre><code>&lt;i:Interaction.Triggers&gt;
    &lt;i:EventTrigger EventName="SelectionChanged"&gt;
      &lt;cmd:EventToCommand 
      Command="{Binding Main.SelectedRecordCommand, Source={StaticResource Locator}}" 
      CommandParameter="{Binding SelectedItem, ElementName=listBillingRecords}" 
      /&gt;
     &lt;/i:EventTrigger&gt;
  &lt;/i:Interaction.Triggers&gt;
  </code></pre>
  
  <p>Thanks</p>
