it should fire my delete method, but instead I get an error: No parameterless
constructor defined for this object, and the delete method is never called.
Anyone have any ideas?

I just tried out the ObjectDataSource of ASP.NET 2.0. A simple application
works with a GridView bound to an ObjectDataSource. The ObjectDataSource is
set to a (factory) class (PersonFactory) with static methods (Select,
Update, Delete, see below). The factory methods work with instances of a

object passed to the Delete method is always empty (Id == 0;...

useful in your development:

I have a gridview which uses an objectdatasource for its select and

The delete command uses the function below. The delete itself works but
the extra logic which requires parameters AccountDebitID and
AccountCreditID does not work.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".

This is as boiled down as I can make it.
Here is my compilation command:
