if the result set is already in a DataTable object then all you need to do
is
DataView dv = new DataView("dbTable");
Now you can access any of the available methods
dv.Sort("column to sort ASC")
etc ...

if the result set is a DataRow
DataRow dtRow = dbTable.NewRow();
dtRow["field1"] = value
dbTable.Rows.Add(dtRow);

Once this is complete create the DataView

DataTable has a .Select method that may get you what you want.  When you say
that you aren't using a RowFilter, is that  a necessary thing?  Rowfilters
seem made to order for what you want to do.  There are many ways to get what
you want, but it depends on knowng what is the ultimate goal.  You can use a
DataSet.GetChanges and then set its filter for things like Added, Modified
etc if this is what you want.

You can create  a DataView off of ANY datatable, so there's most likely no
need to create a seperate table.. you can use the filter on the primary
table.  But if you need to, you can create a second table and then a view,
and then filter it from there.

Let me know what you want to do...I can be of more help.
