How to add nodes of one instance of treeview to the another instance of same treeview

Question

How to populate the nodes into the newtreeview1 which is the instance of the another treeview1 ? The nodes which is added to the "newtreeview1" should be available in the first instance of the treeview1?

for example; if the treeview1 contains

   |-- Node1
        |-- Node2
           | -- Node3
        |-- Node4

the newtreeview1 should also have the above nodes.

Answer 1

you can do this by cloning each node like this

    private void CopyNodes(TreeView srcTree, TreeView dstTree)
    {
        var ar = System.Array.CreateInstance(typeof(TreeNode), srcTree.Nodes.Count);
        treeView1.Nodes.CopyTo(ar, 0);
        foreach (TreeNode item in ar)
        {
            dstTree.Nodes.Add((TreeNode)item.Clone());
        }
    }

and call the function

CopyNodes(treeView1, treeView2);
