DataList.ShowFooter 屬性

  • 參考

定義

命名空間:
System.Web.UI.WebControls
組件:
System.Web.dll

取得或設定值，指出是否在 DataList 控制項中顯示頁尾區段。

public:
 virtual property bool ShowFooter { bool get(); void set(bool value); };
[System.ComponentModel.Bindable(true)]
public virtual bool ShowFooter { get; set; }
public virtual bool ShowFooter { get; set; }
[<System.ComponentModel.Bindable(true)>]
member this.ShowFooter : bool with get, set
member this.ShowFooter : bool with get, set
Public Overridable Property ShowFooter As Boolean

屬性值

Boolean

如果要顯示頁尾區段，則為 true，否則為 false。 預設值為 true，但是這個屬性只有在 FooterTemplate 屬性不是 null 時才會被檢查。

屬性
BindableAttribute

範例

下列程式代碼範例示範如何使用 ShowFooter 屬性在控件中 DataList 顯示頁尾區段。

注意

下列程式代碼範例會使用單一檔案程式代碼模型，如果直接複製到程式代碼後置檔案，可能無法正常運作。 此程式代碼範例必須複製到具有.aspx擴展名的空白文本檔。 如需 Web Forms 程式代碼模型的詳細資訊，請參閱 ASP.NET Web Forms 頁面代碼模型。
