Using ASP.NET 3.5’s ListView and DataPager Controls: Editing Data

The GridView and DetailsView controls offer built-in editing functionality that can be turned on with the tick of a checkbox. Without writing a line of declarative markup or server-side source code, the page developer gets a decent out of the box editing interface. Namely, each field in the GridView or DetailsView is rendered in its editing interface; BoundFields display a TextBox control while CheckBoxFields display an enabled checkbox. Moreover, a CommandField is added, which displays the Edit, Update, and Cancel buttons, as needed. While the ListView control provides editing support, it requires a bit more work from the page developer to get it going. The reason is because the ListView is defined by templates whereas the GridView and DetailsView are defined by fields. Many fields types, such as the BoundField, can generate their own editing interface, but with templates the page developer is on the hook for specifying the editing interface. Creating an editable ListView control entails defining the editing interface via the EditItemTemplate and adding the Edit, Update, and Cancel buttons in the appropriate spots. This article walks through creating an editable ListView control, with the finished results available for download at the end of the article. Read on to learn more!

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!
