Hi Geoff

There are usually two reason why I would want to use a different dataview. The first was to not move the record pointer for the currently active row while doing some other activity. However, as you explained this is no longer a concern with ADO.net. The second would be to sort the data in a different order which I used to do using a different Index.

Thanks
Simon

That means that I can bind a dataview to a datagrid, the user can be sitting on row #3 in the grid...and I can run a process that loops the entire dataview (maybe to calculate a grand total or something)...all without "disturbing" the grid and the highlighted row.
