I'm loading a grid with records from table1. Then I'm changing some of the
records in the grid. What I want to do is load those records into a dataset
or whatever is recommended and then update table1 with the new information.
How can I do this? What's the best way?
Thanks in advacnce...!

Hi all,
Would someone be able to tell me the most 'graceful' way of removing
unwanted rows from a dataset based on a condition prior to update? OR,
resetting the rows all to unchanged after they are initally added to the
recordset.
I create a dataset, which begins empty after the initial .Fill.
Then I create several rows with some...

My experience with databases using C# has been pretty limited thus far.
Mostly I just use a SELECT statement to populate a DataSet, which is
just read-only (mostly for display on a web page), or maybe go so far as
to build an UPDATE or INSERT query with a couple parameters and just
