Assembly: System.Web.Extensions (in System.Web.Extensions.dll)
The NumericPagerField and NextPreviousPagerField pager fields use the property to determine whether the query string field has been evaluated. If is false, the pager field class processes the page number that is contained in the query string field. It also updates the page properties of the DataPager control. The pager field class uses this property only when the QueryStringValue property is not an empty string or null.
