Handle negative time spans

Question

In my output of a grid, I calculate a TimeSpan and take its TotalHours. e.g.

(Eval(\"WorkedHours\") - Eval(\"BadgedHours\")).TotalH         


        

Answer 1

The simple solution would be to do:

string format = "HH:mm";
if(hours < 0)
  format = "-" + format;

hours = Math.Abs(hours)
