Public Class MobileListItem
Inherits TemplateContainer
Implements IStateManager
'用途
Dim instance As MobileListItem
public class MobileListItem : TemplateContainer, IStateManager
public ref class MobileListItem : public TemplateContainer, IStateManager
public class MobileListItem extends TemplateContainer implements IStateManager

範例
在下列程式碼中，示範了如何使用 SelectionList.Items 屬性的選取項目索引，透過 MobileListItemCollection 類別管理 MobileListItem 物件中的項目。

' Create and fill an array list.

' Bind the array to the list.
