I have a datarelation between two tables and I'm having trouble making this
work. I call an addnew on the datarelation to create my new record. However,
I'm having trouble updating my child table. I haven't found any reasonable
examples to do this. Anyone have any suggestions??

I don't understand how you call addnew on a relation.

Some links (maybe you know this already):

In addition, there's this ADO.Net group:
microsoft.public.dotnet.framework.adonet

Essentially I have a binding source that was created off of a data relation.
When I add records I see them being added to the list however the changes
never seem to make it to the underlying dataset. Does this help clear thinsg
up?

I've no idea. I don't use data binding. Maybe because of these problems.

Hi Andrew,

This might have something to do with the data binding on the form. Did you
bind the controls correctly to the underlying DataSet? Please check the
follwing samples for more information on data binding.
