Your output confuses me - D1//D4//D5//D6//D7, D7 is not a child of D6. Did you type your example out wrong?

up to D6 i got the path. but my requirement is D5 has chils D6 and D7. and D6 and D7 does have childs.
that why...

What effort have you made?
ajitha.pusapati 24-Feb-11 4:47am    
in c#.net windows forms

can you be more specific and for this what code you have written so for and what error it shows?

I am assuming you're talking about WinForms TreeView?
In that case, try something like this;


C#
private string GetPath(TreeNode node)
{
    string path = "";
    for (TreeNode iterator = node; iterator != null; iterator = iterator.Parent)
    {
        path = String.Format("{0}//{1}", iterator.Name, path);
    }
    return path;
}
private void FindPaths(TreeNodeCollection nodes, 
                       IDictionary<TreeNode, string> paths)
{
    foreach (TreeNode node in nodes)
    {
        if (node.Nodes.Count == 0)
            paths[node] = GetPath(node);
        else
            FindPaths(node.Nodes, paths);
    }
}
private void some_click_event(object sender, TreeViewEventArgs e)
{
    IDictionary<TreeNode, string> paths = new Dictionary<TreeNode, string>();
    FindPaths(treeView.Nodes, paths);
}


The paths dictionary will contain all the paths with their leaf node as key.

Hope this helps,
Fredrik

In order to get "D1//D4//D5//D6//D7"
User this code : [TreeView name].PathSeparator = "//"
thats it'.

You're only SEVEN YEARS too late and your answer doesn't solve the problem.
