Master/Detail across Two Pages:
Step 3-Listing the Supplier's Products in ProductsForSupplierDetails.aspx

This step of the VIDEO TUTORIAL will familiarize on how to retrieve a query string parameter value from SupplierListMaster.aspx and use it to display the corresponding products for a particular supplier in this page i.e., ProductsForSupplierDetails.aspx. This is accomplished by adding a new GridView and its corresponding ObjectDataSource controls to this web page. The ObjectDataSource control will be configured to retrieve the products related to a particular supplier by invoking the GetProductsbySupplierID method and passing the SupplierID parameter from the query string value. The ObjectDataSource in this detail page will be configured to seek the SupplierID value as query string parameter during ObjectDataSource configuration. Finally, a demonstration of Master/Detail scenario across two pages will be made at run time. In addition, a navigation link ‘Return to Suppliers’ will also be added to the detail page to return back to the master page when clicked.For detailed information and source code for this step, please refer to the original article.
