Hi I'm trying to diaplay the Description stored in dr[3] after the last child node so it'll display something like this.
-A01
   -product
      -hardware
         - brand
              alpha: new brand
              beta: current leading brand

But when i generate the following code the last child node kept diaplaying this...
            TreeNode: alpha: new brand
            TreeNode: beta: current leading brand

Why is it so?I'd appreciated if help on the code is offered thanks.
foreach (DataRow dr in ordt.Rows)
                    {
                        nodeCheck = new TreeNode();
                        nodeCheck.Name = dr[0].ToString();                        
                        strText = dr[2].ToString();
                        strDesc = dr[3].ToString();
                        strList = strText.Split('.');
                        nodeCheck.Text = strList[strList.Length - 1];
                        if (dr[1] != DBNull.Value)
                        {
                            node = treeview1.Nodes.Find(dr[1].ToString(), true);
                                if (strList.Length == 5)
                                {
                                    nodeCheck.Text = nodeCheck + ": " + strDesc;
                                    node[0].Nodes.Add(nodeCheck);                                  
                                }
                                else
                                { node[0].Nodes.Add(nodeCheck); }
                        }                        
                        else
                        {
                            treeview1.Nodes.Add(nodeCheck);
                        } 
                        nodeCheck.Tag = dr[0].ToString();
                    }

I suspect it's because of line 14. Try to change to:
nodeCheck.Text = strDesc;

I changed it to
nodeCheck.Text = strDesc;
the last child node displayed the description w/o the "TreeNode: "

Sorry for the confusion, what i wanted was
nodeCheck.Text = nodeCheck + ": " + strDesc;
Which is in my case "alpha: description"
But the Treeview kept showing "TreeNode: alpha: description"

You mean without 'nodeCheck + ": " + ' you will not get 'alpha' shown?
nodeCheck.Text = nodeCheck.Text + ": " + strDesc;

nodeCheck.Text = nodeCheck.Text + ": " + strDesc; worked.

nodeCheck is the object. If you show it on the screen, it will just show the object type, which is "TreeNode". What you need is the Text property of that object, which is "alpha".
