Browse and display Folder (Directory) structure contents in TreeView control in ASP.Net

ASP.Net TreeView will display server's folder structure. It is not possible to select any folder and display it contents.

As in ASP.Net there's no control to select a folder and extract its path.

Following is what I have created for you.

HTML

<asp:TreeView ID="TreeView1" runat="server" ImageSet="XPFileExplorer" NodeIndent="15">
    <HoverNodeStyle Font-Underline="True" ForeColor="#6666AA" />
    <NodeStyle Font-Names="Tahoma" Font-Size="8pt" ForeColor="Black" HorizontalPadding="2px"
        NodeSpacing="0px" VerticalPadding="2px"></NodeStyle>
    <ParentNodeStyle Font-Bold="False" />
    <SelectedNodeStyle BackColor="#B5B5B5" Font-Underline="False" HorizontalPadding="0px"
        VerticalPadding="0px" />
</asp:TreeView>

Namespaces

using System.IO;

Code

protected void Page_Load(object sender, EventArgs e)
{
    if (!this.IsPostBack)
    {
        DirectoryInfo rootDir = new DirectoryInfo("D:\\Mudassar\\Vehicles\\");
        this.PopulateTreeView(rootDir, null);
    }
}

private void PopulateTreeView(DirectoryInfo directory, TreeNode treeNode)
{
    foreach (DirectoryInfo dir in directory.GetDirectories())
    {
        TreeNode child = new TreeNode
        {
            Text = dir.Name,
            Value = dir.FullName
        };
        if (treeNode == null)
        {
            TreeView1.Nodes.Add(child);
        }
        else
        {
            treeNode.ChildNodes.Add(child);
        }

        foreach (FileInfo f in dir.GetFiles())
        {
            TreeNode file = new TreeNode
            {
                Text = f.Name,
                Value = f.FullName
            };
            child.ChildNodes.Add(file);
        }

        PopulateTreeView(dir, child);
    }
}
