copied!<p>Here's an elementary sample that I created awhile ago when learning to play with the TreeView. I have now converted the code to VB.NET using an <a href="http://www.developerfusion.com/tools/convert/csharp-to-vb/" rel="nofollow noreferrer">online converter</a> for your benefit.</p> <p>It recursively walks the directory tree starting from the root of the virtual directory and creates nodes for each sub-directory or file encountered. I think this is exactly what you needed.</p> <p>For visual separation, I had used icons to differentiate files from folders (folder.gif and file.gif). You can remove that parameter if you want.</p> <p>Complete ASPX follows (You can paste it into a new page and it should run):</p> <hr> <pre><code><%@ Page Language="VB" %> <%@ Import Namespace="System.IO" %> <script runat="server"> Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs) If Not Page.IsPostBack Then Dim rootDir As New DirectoryInfo(Server.MapPath("~/")) ' Enter the RecurseNodes function to recursively walk the directory tree. Dim RootNode As TreeNode = RecurseNodes(rootDir) ' Add this Node hierarchy to the TreeNode control. Treeview1.Nodes.Add(RootNode) End If End Sub Private Function RecurseNodes(ByVal thisDir As DirectoryInfo) As TreeNode Dim thisDirNode As New TreeNode(thisDir.Name, Nothing, "Images/folder.gif") ' Get all the subdirectories in this Directory. Dim subDirs As DirectoryInfo() = thisDir.GetDirectories() For Each subDir As DirectoryInfo In subDirs thisDirNode.ChildNodes.Add(RecurseNodes(subDir)) Next ' Now get the files in this Directory. Dim files As FileInfo() = thisDir.GetFiles() For Each file As FileInfo In files Dim thisFileNode As New TreeNode(file.Name, Nothing, "Images/file.gif") thisDirNode.ChildNodes.Add(thisFileNode) Next Return thisDirNode End Function </script> <html> <head> <title>Untitled Page</title> </head> <body> <form id="form1" runat="server"> <asp:treeview ID="Treeview1" runat="server"></asp:treeview> </form> </body> </html> </code></pre>
