I am trying to show you that how can we use nested list view control in asp.net. For example, suppose we want to display some categories and subcategories of any records. The following demonstration will show you how to perform this task.
ADO.NET provides consistent access to data sources such as Microsoft SQL Server, as well as data sources exposed through OLE DB and XML. Data-sharing consumer applications can use ADO.NET to connect to these different data sources and retrieve, manipulate, and update data. ADO.NET provides first-class support for the disconnected, n-tier programming environment for which many new applications are written.
