>Whereas I need to clone, I have all kind of errors depending on the data manipulation that is done in the cloned copy. I need to look at this back this afternoon. This is a result of the dataset not being cloned entirely, or as per dependencies of other non shallowed copied items from the Data class.


There's another way - not that I'm sure it will solve the errors - you'll have to test it

			DataSet ds1 = ds.DataSet;   // the original

			DataSet ds2 = ds1.Clone(); // cloned

			using (MemoryStream contents = new MemoryStream())
			{
				ds1.WriteXml(contents);  // save contents to a stream
				contents.Position = 0;
				ds2.ReadXml(contents);
			}
