title: Setting the scrollviewer vertical offset when the scrollviewer is inside a datatemplate (wp7)
body: <p>I have a pivot where each pivotItem contains a scrollviewer.
  What I want to do is to set the scrollviewer's offset to a specific number each time I scroll to a new pivot item. I cannot create a databinding because the offset value is not exposed.</p>
  
  <p>There is a ScrollToVerticalOffset() that i can call, but I need first to find which scrollviewer is currently active and get that object, which means the scrollviewer inside the currently selected pivot item.</p>
  
  <p>I tried to get the scrollviewer by traversing the visual tree based on its name but I always get the 1st scrollviewer.</p>
  
  <p>How could I do that?</p>
  
  <p>thanx</p>
