VB.Net DataGridView update query results

Question

I am currently working in converting an out of date Access application in to a .Net application.

In Access we have a query on a form that contains a list of customers and vehicles where the users can edit the data as required.

I followed the following guide to populate the data grid

http://msdn.microsoft.com/en-us/library/fbk67b6z(v=vs.90).aspx

As you could expect I need to replicate this functionality in .Net, I have been able to populate a DataGridView with the results of a query joining the two tables however I have not been able to work out how to handle the update of the tables through the DataGridView. I understand the as the DataGridView contains the results of a query i need to manually code the UpdateCommand of the DataAdapter and this is where i am stuck.

In Short i need to update two tables though a single data grid view.

Kind Regards

我要做的是添加一个具有唯一键的隐藏列，该唯一键将两个表连接在一起，然后编写两个更新查询（每个表一个），并将隐藏列用作您的参数每个查询中的WHERE子句。
