Initializes a new instance of the NumericPagerField class.

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

Public Sub New

This constructor is typically used when you add fields to a dynamically created DataPager control.

To add a NumericPagerField object dynamically to a DataPager control, create a new NumericPagerField 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 NumericPagerField object to a DataPager control.

    ' Dynamically generated field pagers need to be created only 
    ' the first time the page is loaded.
    If Not IsPostBack Then

      'Find the DataPager control within the ListView control.
      Dim pagerControl As DataPager = _
          CType(ContactsListView.FindControl("ContactsDataPager"), DataPager)

      ' Create a NumericPagerField object to display
      ' the page numbers to navigate.
      Dim pagerField As New NumericPagerField()
      pagerField.ButtonCount = 15
      pagerField.ButtonType = ButtonType.Button

      ' Add the pager field to the Fields collection of the
      ' DataPager control.
      pagerControl.Fields.Add(pagerField)
    End If

    ContactsListView.DataBind()

  End Sub
