None of the collection classes that make up the ADO.NET disconnected model, be it DataSet, DataView, or DataTable have a notion of built-in currency (as the ADO Recordset did, eg, MoveNext). You declare a notion a currency from the outside (declare of variable "i" as use it as a currency pointer yourself, MoveNext is equivalent to i++).
Given the concept of the "i-th" DataRow of a DataTable you can, however, fetch the children or parent of that DataRow. The XmlDocument, OTOH, has a notion of currency, as the APIs and the XPath query model are currency-based rather than set-based. XPathNavigator even has a method called "MoveToNext".

Sorry for the cross-post from DOTNET-CLR, not sure how many folks are over there yet... If I am passed in a DataView, is there any way to tell what the current row is? Here is what I want to be able to do (semi psuedo code)... class Foo { ... public string GetName(DataView dv) { long x = dv.CurrentRow; // ???? return dv.Table.Rows[x]["au_fname"]; } ... } Thanks in advance for any help, curt You can read messages from the DOTNET archive, unsubscribe from DOTNET, or subscribe to other DevelopMentor lists at http://discuss.develop.com.
