This example demonstrates how to use the internal event bubbling mechanism of RadListView for ASP.NET AJAX to execute paging operations using buttons residing inside the listview's body. The requirements for that is to assign CommandName = 'Page' and appropriate CommandArgument values for the corresponding LinkButton/Button/ImageButton controls (the list of internally recognized CommandArgument values is available in the help topic linked at the bottom). Thus the listview instance will fetch the corresponding set of data from its data source and display the results.

Keep in mind that you need to specify ItemPlaceholderID property value for RadListView which matches the id of an ASP.NET server control (with id and runat=server properties set) which will be used as a holder of the actual listview data content. The RadListView instance on the example has asp PlaceHolder defined inside its LayoutTemplates for this purpose.
