title: How do I format a timespan in SSRS to show more than 24 total hours in HH:MM:SS?
body: <p>I want to add a total row in SSRS table to calculate total call time. 
  Since total call time is more than 24, i used Timespan expression which produces a result</p>
  
  <p>= system.TimeSpan.FromTicks(Sum(Fields!Call_Time.Value))</p>
  
  <p>However, i am seeing the total hours formatted 11.15:02:45 while i want to see it in HH:mm:ss format. </p>
  
  <p>How can I format the above Timespan expression to show the >24 hours total time in hh:mm:ss?</p>
