title: Accessing UI controls in Viewmodel
body: <p>I have Stackpanel with Buttons as follows,</p>
  
  <pre><code>&lt;StackPanel Orientation="Horizontal" HorizontalAlignment="Center" Margin="0 10 0 0" Name="mystack"&gt;
      &lt;Button Width="30" Name="btn1" Height="30" Content="1" Margin="10"/&gt;
      &lt;Button Width="30"  Height="30" Content="2" Margin="10"/&gt;
      &lt;Button Width="30"  Height="30" Content="3" Margin="10"/&gt;
      &lt;Button Width="30" Height="30" Content="4" Margin="10"/&gt;
  &lt;/StackPanel&gt; 
  </code></pre>
  
  <p>How to make these buttons as single object and use that in viewmodel?<br>
  because I have to check each and every buttons "Content" with my viewmodel property..   </p>
