How can i refresh the Treepanel in server side

[NishaLijo]

Hi,

I am binding the tree dynamically with this code.

 if (!X.IsAjaxRequest)
            {

                Ext.Net.TreeNode treeNode = new Ext.Net.TreeNode();
                treeNode.Text = "Categories";
                TreePanel2.Root.Add(GetNodes(0, treeNode));
                treeNode.Expanded = true;

}

 private Ext.Net.TreeNode GetNodes(int Row, Ext.Net.TreeNode treeNode)
        {
            DrmsDBDataContext db = new DrmsDBDataContext();

            var lst = from p in db.FoodMenuCategories where p.ParentID == Row select p;
            foreach (FoodMenuCategory fc in lst)
            {
                Ext.Net.TreeNode treeNode2 = new Ext.Net.TreeNode();
                treeNode2.NodeID = fc.FDMenuCatID.ToString();
                treeNode2.Text = fc.FDMenuCatName;
                treeNode2.Qtip = fc.FDMenuCatName;
                treeNode2.NodeID = fc.FDMenuCatID.ToString();
                var lst1 = from p in db.FoodMenuCategories where p.ParentID == fc.FDMenuCatID select p;
                if (lst1.Count() > 0)
                    GetNodes(fc.FDMenuCatID, treeNode2);
                treeNode.Nodes.Add(treeNode2);

            }
            return treeNode;

        }

First i binded the tree with category name.when we add the new category,i want to refresh the treepanel dynamically.i used this code

Treepanel.Reload();
