Hi,
Thanks for the reply.
I am binding the GridView to a generic list of TimeSpentTimeStrings,
List<TimeSpentTimeStrings>.
The TimeSpentTimeStrings class looks like this.
public class TimeSpentTimeStrings
{
public DateTime Date { get; set; }
public TimeString Direct { get; set; }
public TimeString Indirect { get; set; }
public TimeString Travel { get; set; }
public TimeString Notes { get; set; }
}
I have been able to bind it, but only if I use TemplateFields for the
TimeString properties. The DateTime field binds with a BoundFields. I
have pasted the code below. I am wondering if there are changes that I
can make to either the TimeString class or the TimeSpentTimeStrings
class so that I could bind the TimeString fields to the Gridview just
as easily as the DateTime fields bind to the GridView.
I think I am getting into some more advanced territory that has not
been covered in the few books I have read about ASP.NET and C#. If
anyone out there can recommond some good reading material that covers
this sort of thing that would be great.
Thanks Again,
Paul
