title: WinRT - How to add popups as tooltips when I click a gridview element
body: <p>On a windows store app project, I have a <code>Gridview</code> that shows images of users inside a circle, I'm trying to do a popup that shows information of that user when I click on of the circles with the image.</p>
  <p>It would look something like this.</p>
  <p><a href="https://i.stack.imgur.com/iFOpp.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/iFOpp.png" alt="enter image description here" /></a></p>
  <p>How can I get the position of the item clicked, to know where the popup appears?
  And how can I do different instances of the same popup with the different information?</p>
  <p>Or is there a better solution to achieve this?</p>
