Using ASP.NET 3.5’s ListView and DataPager Controls: Deleting Data
The previous installments in this article series have demonstrated how to display, group, sort, and page through data using the ListView control. In addition to displaying data, the ListView control also provides support for inserting, updating, and deleting data. If the ListView uses a data source control (such as a SqlDataSource or ObjectDataSource) and that data source control is configured to support insert, updating, or deleting, then implementing such functionality in the ListView does not require writing a single line of code. Rather, adding inserting and updating support entails creating templates that define the inserting and updating user interfaces and Button controls that trigger the actual update or insert. Implementing deleting support requires simply adding a properly configured Delete button to the ItemTemplate. This installment and the next explore how to perform inserts, updates, and deletes using the ListView control. This installment focuses on deleting and shows how to perform simple, standard deletes as well as more advanced deleting scenarios. The demos explored here (as well as the demos from previous installments) are available for download at the end of the article. Read on to learn more!
