This step of the VIDEO TUTORIAL will demonstrate on how to create a custom method titled ‘DiscontinueAllProductsForSuppliler’ to the Products Table Adapter (DAL) of the Northwind.xsd typed dataset as well as ProducstBLL business logic layer. This newly created custom method is invoked from a custom button that is added to the FormView control listing a supplier on the CustomButtons.aspx web page. For detailed information and source code for this step, please refer to the original article.

This step of the VIDEO TUTORIAL (included in Step 4) will show case the addition of a command button titled ‘Discontinue All Products’ is added to the ItemTemplate of the FormView control with its ‘OnClick’ event assigned to an alert message. And a custom event handler of the FormView’s ItemCommand handler will trigger the command button’s click event to invoke the ‘DiscontinueAllProductsForSupplier’ method from the ProductsBLL after alerting the end user with a confirming message. A run time demonstration of the newly created functionality of discontinuing the products belong to particular supplier is shown when the end user clicks on the command button in the FormView control on the CustomButtons.aspx web page. For detailed information and source code for this step, please refer to the original article.
