以上四个方法就是本例子的代码,由于页面较长,笔者就不截图了,注释也都写上,核心的思想就是使用递归算法,请注意,当您直接使用笔者的代码时请确保您的sharepoint站点下存在名为”我的文档”的文档库

生成项目,可以在输出框中看到已经自动将.dll和.ascx文件复制到sharepoint站点的bin和wpresources目录下

打开sharepoint网站首页,进入”文档中心”子站点,依次选择”网站操作”->”编辑网页”

在左栏区域单击”添加Web部件”

找到QuickPart,二者选一个即可,单击添加按钮

此时页面仍然处于编辑状态,并且在左栏的WebPart区域成功添加了ProviderQuickPart部件,下面我们编辑它

选择”编辑”->”修改共享Web部件”

在页面右边弹出的SideBar上就可以看到我们生成的用户控件TreeCatalog了,选择它并单击确定按钮

选择”退出编辑模式”

当您重新打开sharepoint站点时就可以看到将名为”我的文档”的文档库成功绑定到TreeView控件上了
