How to animate a treeview from scratch?

How to build an ASP.NET TreeView From Scratch...?

• I am trying to build a nested/threaded comment system in ASP.NET. I don't know how the PHP guys do it. Its much harder than first imagined. I am trying my damnedest get Hierarchical data to output to the user, but its not working. I have a table with text, a itemID and a parentID. I want to display the information in a tree view format, but asp.net's standard control just doesn't work... Can anyone point me in the right direction of how to output this into a treeview. I have tried nesting repeaters, straight out html building from codebehind and the treeview control. I still haven't found a solution... Can anyone help me out?

  Quickly, by head (could not check in VS2k8 now), I would do it something like this using Linq to SQL private void BuildTree() { List<Item> items = from item in dataContext.Items select item; List<Item> rootItems = items.FindAll(p => p.ParentID == null ); foreach ( Item item in rootItems ) { TreeViewNode tvi = new TreeViewNode(item.text); BuildChildNodes(tvi, items, item.ID); YourTreeNodeName.Nodes.Add(tvi); } } private void BuildChildNodes(TreeViewNode parentNode, List<Item> items, long parentID) { List<Item> children = items.FindAll ( p => p.ParentID = parentID ); foreach( Item item in children) { TreeViewNode tvi = new TreeViewNode(item.text); parentNode.Nodes.Add(tvi); BuildChildNodes(tvi, items, item.ID); } }
