title: Accessing XAML Object in another CS File
body: <p>I need to change the fill of a rectangle from another CS file. A static method in xaml.cs cannot allow access to the Rectangle Object.</p>
  
  <pre><code>public void changeStatusIndicator()
      {
      this.StatusIndicator.Fill = new SlidColorBrush(Color.FromRgb(100,0,0));
  }
  </code></pre>
  
  <p>I need to call this function from another CS file.</p>
  
  <p>[Edit] 
  I want to change the fill property of the Rectangle form another CS File.</p>
