yup Aman id no is there –

只是將該id綁定到數據素材中的文本塊。這就是我在列表框中所做的，我認爲這同樣適用於LLS。 –

id no是不同的它像201，1002任何事情，但我想要1,2,3 –

不是最好的解決方案但可以在某些方面幫助你。

在您的任務列表類型的類定義

只是在那裏的任務列表是越來越充滿

使循環這樣

for (int i = 0; i < TaskList.Count; i++) 
{ 
TaskList[i].BindingId= i; 
}

的地方添加一個成員一樣

public class YourClass 
{ 
public int BindingId{get;set;} 
}

現在

完成循環後，您將獲得一個自動增量號碼附在列表中的每個項目上。只是用它來綁定。
