I've built a User Control that contains a ListView. To make it work I need to pass to it a DataTable. The columns of this DataTable need to have particular names that match up with what the ListView is expecting. I have a large DataTable that I need to massage/convert over to this different format. To do that I need to filter out columns and rename the column names. The actual data in the DataTable doesn't need to change. Is there a good way to do this without actually instantiating a new DataTable and copying the data from the large DataTable into it?
