title: How do I set the selection border color in Flex Spark Datagrid
body: <p>I have a custom skin applied to a Flex 4 spark datagrid. One really annoying issue I am having is finding the ability to override or change the selected row border color. I was able to set the selectionColor just fine but the border is still the default light blue color. I need it to be yellow.</p>
  
  <p>Anyone know where I can find this style or override this border that is being set when selection happens within the skin itself.</p>
  
  <p>thanks,
  -Matthew</p>
