Gets the value of the query string field from the URL of the request.
Assembly: System.Web.Extensions (in System.Web.Extensions.dll)
When the DataPager.QueryStringField property is not an empty string or null, the DataPager control uses the HTTP GET command to navigate through the pages. A query string field that consists of a name/value pair is added to the URL of the page. The property retrieves the value of the query string field from the URL of the request. The property contains the requested page number.
This property is used by the NumericPagerField and NextPreviousPagerField pager fields to evaluate the index of the first record for the page of data requested. The page properties of the DataPager control are then updated.
