I've developed an application that uses DataSet's for data storage. Now
I had this idea to make things easy that I could hook into the
DataTable's OnRowChanged delegate to know when to Update the dataset. So
when a OnRowChanged is fired I connect to my local database and invoke
Update on the dataset. Only problem is while in the callback the row hasn't
actually been added to the dataset back. So what again is the different
between OnRowChanged and OnRowChanging?
This is very fustrating. I dont like having to explicitly Update my
database everyplace I decided to change the data, but hey I'm kind of now
using the disconnected 'feature' of DataSet's. :)

Hi John,

This is a bit unusuall concept.
Why would you need to sync data immediately?
And yes, RowChanged won't work for you.

Changing occurs before the row is Changed.
