How to have an array of Treenode

Question

I would like to have an array of treenode in such a way that if i add a custom node along with that the remaining Nodes declared in the array should be added as child nodes to that custom node added.

Initially i will have a treeview with a Header node if i righ click on that i will have contextmenu with an option addnew. when i click on that i will have a save file dialog option to save a file and i will bind it as child node to that root node. ALong with that i would like to add some more nodes as child nodes to the binded one

Try this tutorial http://www.java2s.com/Code/CSharp/GUI-Windows-Form/TreeViewExample.htm

Answer 2

One option would be to simply make the array as stated and then when you want to add them as children of a newly created node foreach through them:

foreach(var node in nodeArray)
    newNode.Nodes.Add(node);

Something along those lines should do the trick for you.

  This got the answer for me

   private void AddNew_Click(object sender, EventArgs e)
    {
        Stream myStream;
        SaveFileDialog saveFileDialog1 = new SaveFileDialog();

        saveFileDialog1.InitialDirectory = @"C:\";
        //saveFileDialog1.CheckFileExists = true;
        //saveFileDialog1.CheckPathExists = true;
        saveFileDialog1.DefaultExt = "txt";

        saveFileDialog1.Filter = "(*.txt)|*.txt";
        saveFileDialog1.FilterIndex = 2;
        saveFileDialog1.RestoreDirectory = true;

        if (saveFileDialog1.ShowDialog() == DialogResult.OK)
        {

            if ((myStream = saveFileDialog1.OpenFile()) != null)
            {

                string FileName = saveFileDialog1.FileName;
                TreeNode newNode = new TreeNode(FileName);
                newNode.SelectedImageIndex = 1;
                tvwACH.SelectedNode.Nodes.Add(newNode);
                newNode.Nodes.Add("FileHeader");
                newNode.Nodes.Add("BatchHeader");
                newNode.Nodes.Add("EntryDetail");
                // TODO: Add code here to save the current contents of the form to a file.
                //myStream.Close();                
            }
        }
    }
