title: How to put Expander ToggleButton on right
body: <p>By default the expander has a left aligned toggle button but in my WPF app i want toggle button on the right side of the header without the help of Expression Blend. just plain XAML and/or C#. My expander contains a vertically oriented stackpanel which has labels as its child.</p>
  
  <p>I went for its part but <a href="http://msdn.microsoft.com/en-us/library/ms753296.aspx" rel="nofollow noreferrer">here</a> it says "The Expander control does not have any named parts".</p>
  
  <p>I found an example <a href="https://stackoverflow.com/questions/2587683/how-to-align-wpf-expander-control-toggle-button">here</a>. But it overrides the default Expander Style.</p>
  
  <p>I think the attached image should convey what i want. How to do. Any link would be helpful.</p>
