SharePoint 2013 树形导航菜单，读取指定文档库下的文件夹和文件（非JS部分）

SharePoint 2013 树形导航菜单，读取指定文档库下的文件夹和文件

上篇写到文件，因为实际需求是要获得文件。
今天追加代码如下。



Html

<div>
<asp:TreeView ID="TreeView1" runat="server" ExpandDepth="1" OnSelectedNodeChanged="TreeView1_SelectedNodeChanged">
</asp:TreeView>
</div>
<p>
<input id="Text1" type="text" runat="server" /></p>
