Hi Tom, I just had to find a way to create custom section in Umbraco 6.1.6 and boy that took some reading, the documentation is scaddered all over the place.

I'm going to write a blog post about all the steps for creating the custom application but this should help you until I get to it.

If anyone can better my code then that would be appreciated.

You dont need to include anything into the tree config file, it wil be added there automaticly.

[Tree("Application", "Application", "Application")]

    public class populateTree : BaseTree

    {

        public populateTree(string application)

            : base(application)

        { }

 

        protected override void CreateRootNode(ref XmlTreeNode rootNode)

        {

            rootNode.Icon = FolderIcon;

            rootNode.OpenIcon = FolderIconOpen;

            rootNode.NodeType = "init" + TreeAlias;

            rootNode.NodeID = "init";

            rootNode.Action = "javascript:openCategory(-1);";

        }

 

        public override void Render(ref XmlTree tree)

        {

            // Get the current database object

            var db = ApplicationContext.Current.DatabaseContext.Database;

            // Fetch a collection from the db.

            List<Category> listOfCategories = null;

            int key = -1;

            if (!string.IsNullOrEmpty(this.NodeKey))

            {

                key = Convert.ToInt32(this.NodeKey);

            }

 

            listOfCategories = db.Fetch<Category>("SELECT * FROM Categories WHERE deleted=@0 ORDER BY name", false);

 

            if (listOfCategories != null)

            {

 

                foreach (Category category in listOfCategories.Where(x => x.parentId == key))

                {

                    string id = category.treeId.ToString();

 

                    // Create tree node

                    var node = XmlTreeNode.Create(this);

                    node.NodeID = id;

                    node.Text = category.name;

                    node.Icon = "folder_o.gif";

                    node.Action = "javascript:openCategory(" + node.NodeID + ");";

 

                    // Add child nodes

 

                    bool hasChildren = listOfCategories.Where(x => x.parentId == category.treeId).Any();

 

                    node.Source = hasChildren ? this.GetTreeServiceUrl(node.NodeID) : "";

 

                    // Add the node to the tree

                    tree.Add(node);

 

                }

 

            }

 

        }

 

        public override void RenderJS(ref StringBuilder Javascript)

        {

            Javascript.Append(@"

            function openCategory(id) {

                document.getElementById('right').scrolling = 'auto';

                UmbClientMgr.contentFrame('../App_Plugins/PluginName/Category/List?id=' + id);

            }

            ");

        }

    }

Cheers mate,

I'll take a look tonight and let you know how I get on.

Thanks, Tom
