This example demonstrates the usage of data and layout templates in RadListView for ASP.NET AJAX. These templates allows you to define the look and feel of the common layout template of the control (LayoutTemplate), the items in it (ItemTemplate/AlternatingItemTemplate and ItemSeparatorTemplate) and the content that will be shown when there is no data available (EmptyDataTemplate).

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 three RadListView instances on the example have asp PlaceHolder and asp Panels defined inside their LayoutTemplates for this purpose.
