Initializes a new instance of the NextPreviousPagerField class.

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

public NextPreviousPagerField()

Use the NextPreviousPagerField constructor to initialize a new instance of the NextPreviousPagerField class. This constructor is typically used when you are adding fields to a dynamically created DataPager control.

To add a NextPreviousPagerField object dynamically to a DataPager control, create a new NextPreviousPagerField object, set its properties, and then add it to the field collection for the DataPager control.

The following example shows how to use the constructor to dynamically add a NextPreviousPagerField object to a DataPager control.
