How to Bind DataTable into Treeview

How to Bind Datatable into Treeview using C#,

I am using visual c# express, and there was a case, I have a table like this:

I Only have 2 Column, that is ParentID and CustChannelID

ParentID Column is a parent from CustChannelID Column

and What I wanted is create a treeview like this one

and this is my method

        private void frmDODaily_Load(object sender, EventArgs e)

        {

            //I defined the function of Initialization Tree

            treeV();

        }

        private void treeV()

        {

            //Get Class to get database

            csDailyDO dodaily = new csDailyDO();

           //Define the tree

            TreeNode tree = new TreeNode();

            //Get Datatable, you should know how to get one from your database

            DataTable data = dodaily.ChannelTree(“MTL_”);

            //Initial for first tree

            tree = createnode(tree, data, “LOCAL”);

            tree.Text = “LOCAL”;

            treeView1.CheckBoxes = true;

            treeView1.Nodes.Add(tree);

        }

//and this is my method, please shared to anyone

        private TreeNode createnode(TreeNode parent, DataTable data, string LatestKey)

        {

            TreeNode result = new TreeNode();

            TreeNode temp = new TreeNode();

            foreach (DataRow row in data.Rows)

            {

                if (row[“ParentID”].ToString() == LatestKey)

                {

                    temp = createnode(parent, data, row[“CUSTCHANNELID”].ToString());

                    temp.Text = row[“CUSTCHANNELID”].ToString();

                    result.Nodes.Add(temp);

                }

            }

            return result;

        }
