title: Passing the all column values to a multibinding
body: <p>I have a ListView that is configured as a GridView. It is databound to a DataTable and displays several columns of ints. I'd like to display the maximum value in each column in the bold font. </p>
  
  <p>To do this, I have a MultiBinding on the FontWeight of each cell. It is easy enough to pass the cell value to the MultiBinding converter. But how do I pass all of the items in that column to the converter? Or is there a way to pass the the entire databound DataTable to the converter?</p>
