title: ASP.Net, How to use Microsoft Chart Control's onmouseover to populate a GridView
body: <p>I am trying to figure out the optimal way to accomplish, if that is even possible, a master-detail relationship between the markers in the Line Chart (Microsoft Charting) and a GriView on mouseover.</p>
  
  <p>I found an example when this is done with Chart_Click event, using UpdatePanel and AsyncPostBackTrigger. 
  However, I'm puzzled about doing this with onMouseOver event of a Chart control.</p>
  
  <p>I need to be able to change GridView based on a value in a Marker on MouseOver.</p>
  
  <p>Thank you in advance!</p>
