title: WPF datagrid row details peek (layers)
body: <p>i am looking for a way to quickly peek into collapsed row details in DataGrid. </p>
  
  <p>when a user mouses over the rows, there should be a quick peek layer next to the cursor that would have a summary of what is in details. Ultra fast is key here.</p>
  
  <p>looking for something equivalent to layered div in DHTML. No transparency effects needed. </p>
  
  <p>From what i've seen on this forum, this is not inherently supported? i'd need to show a separate window? </p>
