In MS Reporting Services 2008, I have a field that is a duration stored as seconds. Is there a slick way to get it into hh:mm:ss format in a group section of the report?
If you just want to display it, convert in an expression for the Value of the textbox:
=Format(DateAdd("s", Fields!MySecondsField.Value, "00:00:00"), "HH:mm:ss")
If you want to do calculations on it, convert the seconds to a DateTime in your dataset. Using SQL:
SELECT DATEADD(ss, MySecondsField, '1900-01-01') AS SecondsAsDateTime
FROM TimeTable
In Linq this would be something like:
var qry = from Q in t.TimeList
select new
{
SecondsAsDateTime = DateTime.Today.AddSeconds(Q.MySecondsField)
};
Then you can just format it as a normal DateTime.
