title: AdvancedDataGrid SummryRow
body: <p>One update:
  I tried using the SummaryRow on the datagrid for its basic functionalities and it is working. Now, I need to embed the text in the summary fields. E.g. If one of my summaryfields returns me the count then it should be able to display 'TOTAL (count)'</p>
  
  <p>Is it possible with the summaryrow? </p>
  
  <p>Also, I need to have the data to be formatted when it is displayed. e.g. %age, like 50%, 0.1%, etc.</p>
  
  <p>Is this also possible?</p>
  
  <p><em>Hi,
  One quick question. I have an AdvancedDataGrid. I need to add a summaryrow to the grid which will contain SUM/AVERAGE of the respective columns in the ADG. Can anyone point me to some tutorial or any reference where I can learn how to create a summaryrow?
  Thanks!</em></p>
