Datatable in ViewState... why does this work?

[cmay]

I was suprised to see that you can put a DataTable into viewstate on a
page.

Why does this work? I had understood that the DataTable was in
serializable, which I thought was a requirement of being stored in the
viewstate.

It is serializable.

public class DataTable : MarshalByValueComponent, IListSource,
ISupportInitialize, ISerializable

Interesting.

Why does MS say "The DataTable, DataRow, DataView, and DataViewManager
objects cannot be serialized and cannot be returned from an XML Web
service" from :
http://support.microsoft.com/default.aspx?scid=kb;en-us;306134

Does it need to be XMLSerializable for the webservice to use it?

Microsoft has example code returning DataTable objects from web services?

Are you asking IF they do, or stating THAT they do.

I was stating that they do. I was questioning why you assumed this. In all
of the web services examples on msdn I have seen, they showed the performance
reasons why you would/wouldn't use a table/dataset.
