[2.0] Issue on sorting a treeview.

[mar_zim]

I loaded hundreds of data in treeview w/ child nodes and I want it to be sorted but the problem occur when I used the sort() property of the treeview the child nodes get lost. Any one same issue with this?

btw Is it advisable to load a bunch of data in treeview for the sake of easy browsing or not?

My next option is just used combobox.

If your going next attempt is with a combo box then wouldn't a list box be good enough instead of a tree view? And no, I've never heard of nodes disappearing when you call Sort(). How are you loading data into the treeview?

Actually the data has a heirarchy that's why I used treeview. I just loop to populate my treeview. If you populate a treeview w/ a hundred's of data and call the sort property the child nodes disappear. I don't know maybe it's a bug or i'm the bug.

Well I opened a brand new project and put a TreeView and Button on the form and here is the complete code I used:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;

namespace TreeViewTest
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();

            for (int i = 0; i < 20; i++)
            {
                TreeNode node1 = treeView1.Nodes.Add(i.ToString());
                for (int j = 0; j < 10; j++)
                {
                    TreeNode node2 = node1.Nodes.Add(j.ToString());
                    for (int k = 0; k < 3; k++)
                    {
                        node2.Nodes.Add(k.ToString());
                    }
                }
            }
        }

        private void button1_Click(object sender, EventArgs e)
        {
            treeView1.Sort();
        }
    }
}

It loaded the tree correctly, and after I pressed the button it sorted everything and every single node was still there. So, what are the differences between this example and your project?

Try to add up to 500 data in your nodes then call the sort property and tell me if its ok.

I think you should create your own separate test projects and run your own tests.
