title: How do I get the Chart Series' Parent's Parent's Parent's detail?
body: <p>I am having some difficulties of getting the ancestor of a chart series on silverlight.</p>
  
  <p>I can get the parent, but it is a type of Primitive, and then I can get to the parent of that parent by specifying the type, however, I am not sure how many level deep can that be when it reaches to the Chart, and I would like to get to the Chart.</p>
  
  <p>Can someone guide me to do that in code without specifying the type of the parent.</p>
  
  <p>Thanks</p>
