備註

如需實例 RepeaterItemEventArgs 的初始屬性值清單，請參閱建 RepeaterItemEventArgs 構函式。

如需如何處理事件的詳細資訊，請參閱處理和引發事件。

建構函式

RepeaterItemEventArgs(RepeaterItem)

初始化 RepeaterItemEventArgs 類別的新執行個體。

屬性

Item	取得與事件關聯的 RepeaterItem。

方法

Equals(Object)	判斷指定的物件是否等於目前的物件。 (繼承來源 Object)
GetHashCode()	做為預設雜湊函式。 (繼承來源 Object)
GetType()	取得目前執行個體的 Type。 (繼承來源 Object)
MemberwiseClone()	建立目前 Object 的淺層複製。 (繼承來源 Object)
ToString()	傳回代表目前物件的字串。 (繼承來源 Object)
