Larry,

You're on the right track. As far as how to determine CurrentRow, you didn't say how you're navigating the dtOrderDetail ... is this table used to populate a Grid? Or are you navigating by other means? In any case, you will need to mess with the BindingContext to get the current position. Also, you need a few extra quotes to specify the RowFilter correctly. I hope my VB syntax is accurate:

CurrentRow = Me.BindingContext(dtOrderDetail).Position
dvProducts.RowFilter = "ProductID = '" + dtOrderDetail.Rows(CurrentRow)('ProductID') + "'"

You will need to put this code in whatever event handles the row changes (this depends on what you're using for navigation).

Does this help?
