Functional Items
Functional items are static rows in the grid that provide built-in functionality, such as paging, commands, or status information.
Pager Item
The Pager is a row that contains the paging navigation controls. To have the grid divide its data into pages, set the grid's AllowPaging property to True.
You can define the style of the pager row using the RadGrid property builder or the PagerStyle section of the RadGrid property pane.
CommandItem
The CommandItem is a placeholder for commands that perform actions on selected items or all items in the grid. See the Command reference topic for details about the commands you can add to the CommandItem.
StatusBarItem
The GridStatusBarItem appears below all other items in the grid and displays information about the current grid status. It is intended primarily for use when RadGrid is used with RadAjaxManager to indicate that the grid is performing asynchronous AJAX requests. To show the status bar item, set the grid’s ShowStatusBar property to true.
You should have a data source assigned in order to use RadGrid with a status bar.
