備註

列舉 BulletedListDisplayMode 表示您可以套用至控制項中 BulletedList 清單專案內容的顯示行為。屬性 BulletedList.DisplayMode 會使用這些列舉值來設定控制項中 BulletedList 清單專案內容的顯示行為。例如，如果您將 BulletedList.DisplayMode 屬性設定為 HyperLink 值，控制項中的每個 BulletedList 清單專案內容都會轉譯為超連結。

值 Text 可讓您將清單專案內容顯示為一般文字，而不需要額外的功能。

值 HyperLink 可讓您將清單專案內容顯示為超連結。按一下時，超連結會巡覽至 URL。 ListItem.Value使用屬性來指定超連結巡覽的 URL。

值 LinkButton 可讓您將清單專案內容顯示為連結按鈕。當使用者按一下連結按鈕時， BulletedList.Click 請使用事件回傳至伺服器。使用類別的事件資料 BulletedListEventArgs ，判斷使用者按一下的連結按鈕 BulletedList 索引。
