I am populating a treeview in form1 based on the checkeditems in checkedlistbox which is in form2 but am unable to list the subfolders and files of the checked folder..

Can anyone please help me????


Your question is not very clear.
If you are looking to display folder structures in a treeview, go through
C# File Browser[^]
Enhanced BrowseForFolder styled TreeView[^].

Here[^] is a simpler example that can help you get started.

        private static TreeNode CreateDirectoryNode(DirectoryInfo directoryInfo)
            var directoryNode = new TreeNode(directoryInfo.Name);
            foreach (var directory in directoryInfo.GetDirectories())
            foreach (var file in directoryInfo.GetFiles())
                directoryNode.Nodes.Add(new TreeNode(file.Name));
            return directoryNode;

        private void button1_Click(object sender, EventArgs e)
            foreach (var obj in opt.checkedListBox1.CheckedItems)

You can call function on click on tree node, once the node event fire, you can check for the new path and generate the new sub node, I have done and it worked

if you want I can share the same with you
