DataPager.Fields 屬性

定義

取得 DataPagerField 物件的集合,這些物件表示 DataPager 控制項中指定的頁面巡覽區欄位。

public:
 virtual property System::Web::UI::WebControls::DataPagerFieldCollection ^ Fields { System::Web::UI::WebControls::DataPagerFieldCollection ^ get(); };
[System.Web.UI.PersistenceMode(System.Web.UI.PersistenceMode.InnerProperty)]
public virtual System.Web.UI.WebControls.DataPagerFieldCollection Fields { get; }
[<System.Web.UI.PersistenceMode(System.Web.UI.PersistenceMode.InnerProperty)>]
member this.Fields : System.Web.UI.WebControls.DataPagerFieldCollection
Public Overridable ReadOnly Property Fields As DataPagerFieldCollection

屬性值

集合物件,包含 DataPager 控制項中指定的所有頁面巡覽區欄位。

下列範例示範如何使用 Fields 屬性,以動態方式將 物件DataPager加入NextPreviousPagerField控件。 此程式代碼範例是建構函式所提供較大範例的 NextPreviousPagerField 一部分。

void Page_Load(Object sender, EventArgs e)
{
  
  // Dynamically generated field pagers need to be created only 
  // the first time the page is loaded.
  
  if (!IsPostBack)
  {
    // Create a NextPreviousPagerField object to display
    // the buttons to navigate.
    NextPreviousPagerField pagerField = new NextPreviousPagerField();
    pagerField.ShowFirstPageButton = true;
    pagerField.ShowLastPageButton = true;
    pagerField.ButtonType = ButtonType.Button;

    // Add the pager field to the Fields collection of the
    // DataPager control.
    ContactsDataPager.Fields.Add(pagerField);
  }

  ContactsListView.DataBind();

}
Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs)
  
  ' Dynamically generated field pagers need to be created only 
  ' the first time the page is loaded.

  If Not IsPostBack Then
    ' Create a NextPreviousPagerField object to display
    ' the buttons to navigate.
    Dim pagerField As New NextPreviousPagerField()
    pagerField.ShowFirstPageButton = True
    pagerField.ShowLastPageButton = True
    pagerField.ButtonType = ButtonType.Button

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

End Sub

備註

呼叫器欄位會依呼叫器字段出現在集合中的順序,顯示在 DataPager 控件中 Fields 。 下表顯示衍生自 DataPagerField 類別且可用於集合中的 Fields 呼叫器字段類別。

呼叫器欄位類型 描述
NextPreviousPagerField 讓使用者一次流覽一頁的數據頁面,或跳至數據的第一頁或最後一頁。
NumericPagerField 可讓使用者依頁碼選取數據頁面。
TemplatePagerField 可讓您建立自定義分頁 UI。

若要以宣告方式指定控件的 DataPager 呼叫器字段,請將專案放在 Fields 控件內 DataPager 。 然後,您可以列出要在開頭和結尾 <Fields> 標記之間包含的呼叫器字段。

您可以程式設計方式將呼叫器欄位新增至 Fields 集合。 不過,在控件中 DataPager 以宣告方式列出呼叫器字段會比較容易。
