Body
There are some unclear moments in your code: <ol> <li>Do you want to explicitly restrict path depth (e.g. show paths up to 3d level only)</li> <li>What is ListWithPaths? Can two paths have a common node?</li> </ol> To show a single path with restriction (depth) the code could be <pre><code>private void PopulateTree(String path, TreeNode parent, int depth) { if (depth == 0) // <- Artificial criterium return; if (String.IsNullOrEmpty(path)) return; int index = path.IndexOf(Path.DirectorySeparatorChar); String directoryName = (index < 0) ? path : path.Substring(0, index); String otherName = (index < 0) ? null : path.Substring(index + 1); TreeNode childNode = parent.Nodes.Add(directoryName); PopulateTree(otherName, childNode, depth - 1); } </code></pre> In order to load a collection of paths without any restriction with possible common nodes you can use something like this: <pre><code>private void PopulateTree(String path, TreeView view, TreeNode parent) { if (String.IsNullOrEmpty(path)) return; int index = path.IndexOf(Path.DirectorySeparatorChar); String directoryName = (index < 0) ? path : path.Substring(0, index); String otherName = (index < 0) ? null : path.Substring(index + 1); TreeNode childNode = null; TreeNodeCollection nodes = (parent == null) ? view.Nodes : parent.Nodes; foreach (TreeNode node in nodes) if (String.Equals(node.Name, directoryName)) { childNode = node; break; } if (childNode == null) childNode = nodes.Add(directoryName); PopulateTree(otherName, view, childNode); } private void PopulateTree(IEnumerable<String> paths, TreeView view) { view.BeginUpdate(); try { foreach (String path in paths) PopulateTree(path, view, null); } finally { view.EndUpdate(); } } ... PopulateTree(ListWithPaths, MyTreeView) </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
