display timestamping for list items like "1 hour 32 minutes ago" in gridview label control
You need to
1. fetch the datetime data for that item
2. Get the difference in datetime from Now (current datetime using DateTime.Now)
3. Use the difference in a defined format as per your need.
Difference of Datetime will be stored/tracked as TimeSpan. There are properties exposed that will directly give you how much days/hours/minutes in the difference.
