    [CLOSED] TreePanel question

    I am trying to do the following

    Say I have list with Parent and children. all Parents have level of 1 and children have level 2, 3 and so on
    I would like to create tree with top level under root expanded using TreeNode and then when clik on parent use AsyncTreeNode. It seems that I can do it if top level are not expanded and using AsyncTreeNode for all levels per some of the examples.

    is it possible to do as per my example.

    Do you need the following functionality or something else?

                if (!string.IsNullOrEmpty(e.NodeID))
                    for (int i = 1; i < 6; i++)
                        AsyncTreeNode asyncNode = new AsyncTreeNode();
                        asyncNode.Text = e.NodeID + i;
                        asyncNode.NodeID = e.NodeID + i;
                    for (int i = 6; i < 11; i++)
                        Coolite.Ext.Web.TreeNode treeNode = new Coolite.Ext.Web.TreeNode();
                        treeNode.Text = e.NodeID + i;
                        treeNode.NodeID = e.NodeID + i;
                        treeNode.Leaf = true;
