 TimeSpan p = new TimeSpan();

  {

       //TimeSpan t2 = TimeSpan.Parse(grid_horas.Rows[i].Cells[7].Value.ToString());

  }

Answer 1

Assuming the .Value is a timespan, then it should just work as:

TimeSpan sum = TimeSpan.Zero;
for ( int i = 0; i < grid_horas.Rows.Count; i++ )
{
   sum += (TimeSpan)grid_horas.Rows[i].Cells[7].Value;
}
// now use sum.Hours, sum.TotalHours, sum.Minutes etc
