Call Backs ASP.NET 2.0

You can use callbacks to update individual elements of a page, such as a chart or a panel, provide different views of the same data, download additional information on demand, or auto-fill one or more fields. In particular, the ASP.NET 2.0 TreeView control uses script callbacks extensively to implement its expand/collapse features and the GridView control uses callbacks to page and sort without explicit postbacks.
