title: How do I change the background color of a cell using WPF Toolkit Datagrid
body: <p>I'm using the WPF toolkit datagrid, and I'd like to set the background color of a cell, not the row, based on the content of the cell.</p>
  
  <p>For the sake of simplicity, lets say the column is called Foo and I'd like the background of the cell to be blue when Foo is 1, red when Foo is 2, Yellow when Foo is 3 and Green when Foo is greater than 3.</p>
  
  <p>If I can do that, I'm pretty sure I can solve any of the more complex cases that I need to deal with.</p>
