RadControls for ASP.NET AJAX
RadDataPager can be used to display paging navigation controls for other
data-bound controls that implement the IPageableItemContainer or
IRadPageableItemContainer interface (like the RadListView and MS ListView). The
RadDataPager control lets users view large sets of data in small chunks for faster loading and easier
navigation. It also provides a set of events, helper methods and properties for custom intervention.
You can easily add the RadDataPager control to a Web Form within Visual Studio. The paging interface
appears wherever you place the RadDataPager control on the page. You may place it before or after the
RadListView control, as well as within its LayoutTemplate element.
The RadDataPager control has the following properties for using it in its default state:
PagedControlID is the ID of the control that implements one of the following
interfaces - IPageableItemContainer or IRadPageableItemContainer. This
is the control that will be paged by RadDataPager control. If RadDataPager is placed in Controls collection
of IPageableItemContainer / IRadPageableItemContainer setting this property is optional. In case
PagedControlID is not set, RadDataPager will attempt to find its container automatically.
PageSize is the number of items and rows to display on each page.
StartRowIndex gets the index of the first record that is displayed on a page of data.
TotalRowCount gets the total number of records that are displayed in the
underlying data source.
MaximumRows gets the maximum number of records that are displayed for each page of data.
RadDataPager field types
The RadDataPager control has a number of fields
you can use, including template support for
designing your own pager. The following table lists the different RadDataPager fields:
