I have a form where I have used tree view control to display File and folder browsed by user.

It displaying fine. I want that , if a user clicks on file , with new window contain all the tree-view nodes and state, means the selected node should be expanded, and selected file should be highlighted in the new form.

I am calling treefill(string path) method from outside of the class.

public string pTreePath { get { return strTreePath; } set { strTreePath = value; } }

How i can achieve this ?

I wonder why? If you already have some tree view, why having two? If you don't need two, why not just moving the original one? Why?

Your description of exactly what you want to do is not specific enough for me to help you.

What exactly does "new instance of same Form" mean ?

Are you saying that when the user clicks on a node in the TreeView in one Form: you want to create another Form with a TreeView on it, and in that TreeView show the Node the user selected in the first TreeView as the "root node" in that TreeView fully expanded ?

If that's what you are saying, yes it can be done, but I'd ask you, just like Sergey did, why do you want to do it that way. What's your goal here ?

Do you only want to show in TreeView1 the nodes which have sub-nodes, but you don't want to all sub-nodes copied ?

My requirement to is that only, actually i am having a user control, that has a tree view control. when user clicks on the file in the tree view , it should open the new instance carrying all the data of tree view.

Hi Arshad,

"it should open the new instance"

In order to be helpful, I need to know exactly what you mean by "new Instance:" do you mean a new instance of the UserControl itself (to be placed within the same Form that contains the first UserControl), or: do you mean a new instance of the TreeView control to be placed within the same UserControl.

Is there a limit to how many instances you are going to create, whether the instances are a UserControl, or a TreeView ?

" carrying all the data of tree view."

The issue of copying over the "data" or "state" also needs clarification: you click on a Node with child Nodes in the first TreeView: and the Node you clicked on's child Nodes have "grand-child" Nodes: do you want to copy only the Child Nodes of the clicked-on Node ... without copying the "grandchildren" Nodes of the clicked on Node ... or: do you want to copy the whole structure that the clicked-on Node "contains" ?

Have you written recursive code in C# before that goes through every possible level of some hierarchic structure, like the ControlCollection of a Form, which may contain Panels within Panels, etc. ?

Have you experimented with the TreeNode.Clone() method exposed by WinForms ?
