範例

下列範例顯示如何使用 ListViewDataItem 物件,從控制項中的專案抓取域值 ListViewThe following example shows how to use a ListViewDataItem object to retrieve a field value from an item in the ListView control.

重要

這個範例有一個可接受使用者輸入的文字方塊,這可能會造成安全性威脅。This example has a text box that accepts user input, which is a potential security threat. 根據預設,ASP.NET Web 網頁會驗證使用者輸入未包含指令碼或 HTML 項目。By default, ASP.NET Web pages validate that user input does not include script or HTML elements. 如需詳細資訊,請參閱 Script Exploits Overview (指令碼攻擊概觀)。For more information, see Script Exploits Overview.

備註

ListViewDataItem類別代表控制項中的個別資料項目 ListViewThe ListViewDataItem class represents an individual data item in a ListView control. 資料項目目通常會對應至資料來源物件中的記錄。A data item usually corresponds to a record in a data source object. 類別衍生自 ListViewItem 類別。The class derives from the ListViewItem class.

控制項中的每個專案 ListView 都有一個以屬性工作表示的指定專案類型 ItemTypeEach item in the ListView control has a designated item type that is represented by the ItemType property. 當專案類型為時 ListViewItemType.DataItem ,您可以使用 ListViewDataItem 類別來取得專案的詳細資訊。When the item type is ListViewItemType.DataItem, you can use the ListViewDataItem class to get more information about the item.

ListView控制項會將資料項目儲存在集合中 ItemsThe ListView control stores data items in the Items collection. 若要判斷 ListViewDataItem 集合中物件的索引 Items ,請使用 DisplayIndex 屬性。To determine the index of a ListViewDataItem object in the Items collection, use the DisplayIndex property. 若要判斷基礎資料來源中資料項目的索引,請使用 DataItemIndex 屬性。To determine the index of the data item in the underlying data source, use the DataItemIndex property. 這些索引屬性之間的差異在於, DisplayIndex 表示資料項目在目前頁面中的位置,而 DataItemIndex 是以頁面位移為基礎。The difference between these index properties is that DisplayIndex represents the position of the data item in the current page, whereas DataItemIndex is based on the page offset. 如果未使用控制項在控制項中啟用分頁功能 ListView DataPager ,這兩個屬性會包含相同的值。If the paging functionality is not enabled in the ListView control by using a DataPager control, these two properties will contain the same value.

您可以使用屬性來存取基礎資料物件的屬性 DataItemYou can access the properties of the underlying data object by using the DataItem property.

DataItem只有在控制項的事件期間和之後,才可以使用屬性 ItemDataBound ListViewThe DataItem property is available only during and after the ItemDataBound event of a ListView control.

如需 ListViewDataItem 類別之執行個體的初始屬性值清單,請參閱 ListViewDataItem 建構函式。For a list of initial property values for an instance of the ListViewDataItem class, see the ListViewDataItem constructor.
