I see where you are telling the DataAdaptor to Update: daGifts.Update( DsGifts1) < I'm assuming DsGifts1 is your Dataset>
But, you are not telling it which Table to update: daGifts.Update( DsGifts1,"tblGi fts") < and I assume that tblGifts is the
table you want to update.>
That appears to me to be the problem. Although, I would think it would throw an error if you doin't specify the table to apply
the update to.

Brett,
Are you sure there is something to update.
Standard you can write
if DSGifts1.hascha nges then
daGifts.Fill(Ds Gifts1)
end if
Than you can as well easily debug that.
I hope this helps?
Cor
Hmmm.... It makes sense to me that the table would have to be included, but
it still does the same thing. Per Cors comment, it looks like there may not
be anything to update cause when using his code it doesnt fill the dataset
again... I dont understand why though, cause I AM making a change to the
datagrid.... Any ideas??

Brett,
I saw but have not the idea you showed where/how you did the update of items
in the rows of a table in the dataset.
The most known problem is that the data is not yet forced in the datset
because of a row change (currencymanage r), that you can do with
BindingContext( ds.Tables(0)).E ndCurrentEdit()
I hope this helps a little bit?
Cor
Brett Im not sure I know what you mean. Im fairly new to .NET, so you'll have to
bear with my ignorance. :-) Shouldnt the dataset be updated because of the
update parameters ?
Yes the should, however there should be data to update.
Do you know the commandbuilder by the way, for the not to difficult select
statements (less than 100 fields and no joins) it makes mostly your
commands.
dim cmb as new commandbuilder( da) http://msdn.microsoft.com/library/de...edcommands.asp
I hope this helps?
