Kevin,

How about using one data table and a data view of that data table filtered on the primary key to get the individual datarow? I looked at the mmBusinessObject.DataSet property, but it is of type DataSet, not mmDataSet, so I cannot keep the view there. Where can I save the data view so I can access it later?

TIA

I have the details in a GridView and want to edit the information in a series of input controls populated from the GridView datatable having the detail information returned to the GridView database when I select another record or click the Save button

The easiest way to get the data back into the GridView is to re-retrieve the data.
