Save DataGridView changes to database through multiple layers

[anthasaurus]

Hi, I have worked through the MSDN example of Creating an N-Tier Data Application. However, I'm struggling to get started with my 'save changes' functionality for a DataGridView. Can anyone offer any advice? My solution consists of SQL Server 2008 (I'm using the NorthWind sample database to go along with the walkthrough linked above), a Data Access Tier, Data Entity Tier, DataService and Presentation Layer and currently my app displays the DataSet in two DataGridViews. I understand the order of method invocations that is required to achieve what I want, but I'm struggling to get started with the coding of it. I.e capturing the changes made in the DataGridView, saving them to the DataSet and then committing the DataSet to the database via the DataService and Data Access Tier. Apologies for the long post and if I have missed out any info that would help you answer my question. Anthony

Ah so it did, as I've corrected it. Thanks for pointing that out.
