title: How to get row count inside Gridview label
body: <p>I have an ItemTemplate Label inside Gridview which I haven't bound with any DataField.
  I have userId as one of the columns of GridView.
  Based on the userId column, I want to get total no of assets acquired by the User. The totalNo doesn't exists in the database. I have to manually fire a query and get total no of row counts.</p>
  
  <p>Now, how to put this rowCount for each user inside GridView?</p>
  
  <p>Any ideas?
  I have tried onRowDataBound and FindControl, but how do I get rowIndex for that particular user?</p>
