DataPager Class

Provides paging functionality for data-bound controls that implement the IPageableItemContainer interface, such as the ListView control.

Namespace:  System.Web.UI.WebControls
Assembly:  System.Web.Extensions (in System.Web.Extensions.dll)

The DataPager class is used to page data and to display navigation controls for data-bound controls that implement the IPageableItemContainer interface. (An example of a control that implements the interface is the ListView control.)

You can associate the DataPager control with the data-bound control by using the PagedControlID property. Alternatively, you can put the DataPager control inside the data-bound control hierarchy. For example, in the ListView control, you can put the DataPager control inside the ListView::LayoutTemplate template.

You can customize the number of items that are displayed for each page of data by changing the PageSize property. You can also change the way a page is submitted to the server by setting the QueryStringField property.

Pager Fields

In order for the DataPager control to display navigation controls, you must add pager fields to the control. The pager fields derive from the DataPagerField class. The following table lists the pager field types that you can use.

Pager field type



Enables users to navigate through pages one page at a time, or to jump to the first or last page.


Enables users to select a page by page number.


Enables you to create a custom paging UI.

To declaratively add pager fields to the DataPager control, add a Fields element to the DataPager control. You can then add the pager fields to the Fields element. The pager fields are added to the Fields collection in the order that they appear in the Fields element. The Fields collection enables you to programmatically manage the pager fields in the DataPager control.

Page Properties

The following table lists read-only properties of the DataPager control that specify characteristics of the page of data. These properties are usually used for binding expressions in the TemplatePagerField object.




The maximum number of records that are displayed for each page of data.


The index of the first record that is displayed on a page of data.


The total number of records that are available in the underlying data source.


The default markup that is rendered default for this control might not comply with accessibility standards, such as the Web Content Accessibility Guidelines 1.0 (WCAG) priority 1 guidelines. For details about accessibility support for this control, see ASP.NET Controls and Accessibility.

The following example shows how to add paging functionality to a ListView control. This example contains two DataPager controls that are used to page through data of the same ListView control.

No code example is currently available or this language may not be supported.
