What I need is when a tree node is selected, the application needs to show the selected folder (or file) details listed. The details should be shown in the same window but separately from the folder hierarchy tree.
I have created app that recursively searches trough files/folders and writes XML file that is later used to fill tree view. My problem is when i fill tree view, it fills it with attributes from xml(size, creation date, last modified ...) and I don't want that, I want it to display just names of files/folders and when I click on tree node that it displays details of specific file/folder.
I used this code to do all that How to create and save an XML file containing complete hierarchy of files and folders for a specified folder?
But the problem is in these lines of code, they display all information in tree view
foreach (var att in xElement.Attributes())
{
treeNode.Text = treeNode.Text + " " + att.Name.LocalName + ":" + att.Value;
}
Can anyone help me solve this problem, how to display file/folder details when tree node is selected
This is my whole code
public partial class frmMain : Form
{
XDocument xDoc = null;
string path = null;
public frmMain()
{
InitializeComponent();

{
listDetails.Items.Clear();

if(fwd.ShowDialog() == DialogResult.OK)
{
lblPath.Text = "Path: " + fwd.SelectedPath; // Shows path selected by user
path = fwd.SelectedPath; // stores that path in string for later use
}
CreateXML();
CreateTree();
