Sharepoint 2010 - webpart treeview無法正常工作

您好我正在使用SharePoint 2010，並在webpart中創建樹視圖以顯示文檔庫中的項目。此代碼不適用於我，它顯示在同一網絡中的所有內容... 我希望能夠指定使用哪個文檔庫。Sharepoint 2010 - webpart treeview無法正常工作

另外它放入重複節點，所以如果我去編輯頁面，它會添加一個重複的，如果我離開編輯模式，它會添加另一個重複。 enter image description here

任何人都可以幫忙嗎？

嘗試的使用語句之前添加此：

If(node.Nodes.Count == 0) { // The rest of your code here }

添加WebProperties到你的WebPart到能夠配置例如，你想改用硬編碼的一個圖書館。在此屬性中，您可以指定列表名稱並讀取它以加載此列表。

同時，爲了避免在編輯多個插件等請添加代碼的Page_Load事件裏面裏面

if (!Page.IsPostBack) 
{ 
    Your code goes here... 
}

這避免你的代碼的執行每次加載甚至投遞的頁面，這將導致你每次將新節點添加到您的樹中。
