Reload TreePanel

Hi,
I created a dynamically treepanel and the first time it appears. However, after removing the children I perform the function to create treepanel again, but it does not appear. What function do I need to run treepanel show again?

Aspx

Code:

---

  function removeTree() {
            var root = TreePanel1.getRootNode();
            while (root.childNodes.length > 0) {
                root.removeChild(root.childNodes[0]);
            }
        }
 
  <ext:ToolbarButton ID="btnRefreshTree" runat="server" Icon="Cross" Hidden="true">
                                <Listeners>
                                    <Click fn="removeTree" />
                                </Listeners>
                                <AjaxEvents>
                                    <Click OnEvent="RefreshTree"/>                                     
                                </AjaxEvents>
                            </ext:ToolbarButton>

Code C#

Code:

---

public void RefreshTree(object sender, AjaxEventArgs e)
        {
            MontarTreeView();
        }
protected void MontarTreeView()
        {           
            Coolite.Ext.Web.TreePanel tree = this.TreePanel1;         
            Coolite.Ext.Web.TreeNode root = new Coolite.Ext.Web.TreeNode();
            tree.Root.Clear();
            root.Text = "Itens Menu Sistema - " + sistema;
            root.NodeID = "-1";           
            root.Expanded = true;           
            tree.Root.Add(root);   
            MenuPrincipal[] menuPai = MenuPrincipalController.RetornarMenuPai(0,sistema);
            foreach (MenuPrincipal mp in menuPai)
            {
                Coolite.Ext.Web.TreeNode nodePai = new Coolite.Ext.Web.TreeNode();               
                nodePai.NodeID = mp.mnuId.ToString();
                nodePai.Text = mp.mnuDescricao;
                nodePai.Icon = ImagemIcone(mp.mnuIcone);               
                root.Nodes.Add(nodePai);
                MenuPrincipal[] menuFilho = MenuPrincipalController.RetornarMenuFilho(mp.mnuId);
                foreach (MenuPrincipal mf in menuFilho)
                {
                    Coolite.Ext.Web.TreeNode nodeFilho = new Coolite.Ext.Web.TreeNode();
                    nodeFilho.NodeID = mf.mnuId.ToString();
                    nodeFilho.Text = mf.mnuDescricao;
                    nodeFilho.Icon = ImagemIcone(mf.mnuIcone);                   
                    nodePai.Nodes.Add(nodeFilho);                   
                }
            }
           
        }

Coolite 0.8.1

Hi,

0.8.x doesn't support creating controls during AjaxEvent. Use the following example to refresh tree
