title: Update ActiveDataItem of XamDataGrid on adding new record
body: <p>I am using WPF with MVVM architecture, The problem I am facing is when I add a new record to the grid and press enter, the record is not set as the active record.
  Its only when I click on some other record and then again on the new record that it gets updated.  </p>
  
  <pre><code>&lt;igDP:XamDataGrid  Name="xamDataGrid1" Width="700" Height="200" HorizontalAlignment="Center" ActiveDataItem="{Binding Listener,Mode=TwoWay}"  DataSource="{Binding GridData.Tables[0].DefaultView}" Padding="50"&gt;
  </code></pre>
  
  <p>Is there a way by which I can set the newly added record to the activedataitem property so that It can make a call to the listener in the view model?
  I have to insert the new record in the database from the view model.</p>
