Hi:
I have created a datatable and I'm able to access it by key values.
I need to be able to go to the "top" of the datatable and process

Hi,
I have a DataSet with a DataTable that has a number of duplicate rows
(except for one column that has a unique value).
Each row has OrderNo, OrderLineNo, etc and there are multiple rows with
