Thank you for the answer.

I'll try to use this information. Too bad the generated in VS typed datasets don't implement those interfaces.

We're having a problem with this issue  in our project. We're binding xamDataGrid to a typed dataset which contains relations. We're able to copy tables to some IBindingList collection, but what should we do with relations? How can we bind xamDataGrid to multiple collections and set relations between them to make the grid show the hierarchy?

Could you please advise anything about that? Thank you

 By merging I mean invoking the "Merge()" method of a dataset.

 Thanks a lot, Joe. That was a big "oops, haven't noticed that!" :)
It works just as expected. But I still have one issue, if I merge the source dataset with another dataset (of the same schema) - nothing happens. When debugging, I clearly see the dataset have been changed, but the grid doesn't catch it. But if I manually change some field in the dataset, everything's fine.

Do you know what causes this problem?

Thanks

 I strongly advocate for a RefreshRecord method that works comparable to WinGrids RefreshRow method. Not only would I like to rebind a single record (in case binding just doesn't pick it up because we have to bind to property that cannot be monitored using IPropertyNotifyChanged), but also have the means to fully recreate a row without having to worry about cell values being cached due to virtualization. I currently have to rebind the whole data source in order to get around these issues...

 Cheers,

Philipp
