问题描述

海，

在我的应用程序中，我有两个名为Treeview1，Treeview2的ASP Treeview控件和四个名为
的按钮 添加，删除，添加，删除.

在第一个树视图中，我选择了一个树节点并单击添加按钮，然后它将成功添加到第二个树视图中.如果我再次添加该节点，它将再次添加到Second treeview，如何防止这种情况，
我写了以下的

Hai,

In my app i have two asp treeview controls named Treeview1, Treeview2, and four buttons named
ADD, REMOVE,ADDALL, REMOVEALL.

In the first Treeview I selected a treenode and clicked ADD button then it will added to the second treeview successfullly. if I add again that node, again it will be added to Second treeview, How I can prevent this,
I wrote the following one

TreeNode node = TreeView2.FindNode(TreeView1.SelectedNode.ValuePath);

if (node != null)
           
   {
   Response.wripte("This node is already exists");
            return;
}

但不能确定所有情况，
