Hello all,<BR><BR>I am looking to retrieve master detail data using ADO, and am looking for a retrieval method and storage structure that will enable me pass the data easily through the layers of my application.<BR><BR>I have three standard layers in my ASP .NET application.<BR><BR>datasets are returned by SQL 2000 stored procedures and bubbled back up to the presentation layere where they are either bound to controls ie. datagrids or unpacked to fill the fields on a form.<BR><BR>I now need to be able to retrieve master detail data, and hold the data in a structure that maintains the relationships within the data. This sam structure woiuld need to be populated prior to any inserts or updates. <BR><BR>Is there a way to use a single dataset to hold and manage mutil dimensional master detail data?<BR><BR>Cheers<BR>Mark.
