I've got an ASP.NET page that has a bunch of controls that need to be populated (e.g. dropdown lists).
I'd like to make a single trip to the db and bring back multiple recordsets instead of making a round-trip for each control.
I could bring back multiple tables in a DataSet, or I could bring back a DataReader and use '.NextResult' to put each result set into a custom business class.
Will I likely see a big enough performance advantage using the DataReader approach, or should I just use the DataSet approach?
Any examples of how you usually handle this would be appreciated.
