title: Infragistics xamGrid for Silverlight: How do I apply conditional formatting for summary row?
body: <p>I have a <code>TextColumn</code> in xamGrid which has summary enabled. What i want to do is display the sum in red if it is negative. This is how the column is defined:</p>
  
  <pre><code>&lt;igGrid:TextColumn Key="Col1" HeaderText="Col1" 
   ValueConverter="{StaticResource NumberFormatter}"  ValueConverterParameter="#,##0" &gt;
       &lt;igGrid:TextColumn.ConditionalFormatCollection&gt;
         &lt;igGrid:LessThanConditionalFormatRule Value="0.00" StyleToApply="{StaticResource RedBrush}"/&gt;
       &lt;/igGrid:TextColumn.ConditionalFormatCollection&gt;
       &lt;igGrid:TextColumn.SummaryColumnSettings&gt;
         &lt;igGrid:SummaryColumnSettings&gt;
           &lt;igGrid:SummaryColumnSettings.SummaryOperands&gt;
             &lt;igGrid:SumSummaryOperand IsApplied="True" FormatString="{}{0:N}"/&gt;
             &lt;igGrid:MaximumSummaryOperand FormatString="{}{0:N}"/&gt;
             &lt;igGrid:MinimumSummaryOperand FormatString="{}{0:N}"/&gt;
           &lt;/igGrid:SummaryColumnSettings.SummaryOperands&gt;
         &lt;/igGrid:SummaryColumnSettings&gt;
       &lt;/igGrid:TextColumn.SummaryColumnSettings&gt;
  &lt;/igGrid:TextColumn&gt;
  </code></pre>
  
  <p>How do i specify that the conditional formatting should be used not only for the column cells but also the summary cell?</p>
