Hi,
I am completely new to telerik... We are about to buy but I am having some troubles to get started ..
I try to bind the treeview to the following structure:

- Assessment
- Folder
- Folder
....
- Assessment

(assessment is an own domain object and folder too)

I am getting all assessment as a list<Assessment> and those can contain 0-n folders. I tried to bind the treeview to the assessments and call the assessments Folders property within NodeDataBound.

Thats the page_load:

    
            protected void Page_Load(object sender, EventArgs e) { 
        
                    if (!IsPostBack) { 
        
                        RadTreeView1.DataSource = new NHibernateDaoFactory().GetTagGroupDao().GetAll(); 
        
                        RadTreeView1.DataBind(); 
        
                        RadTreeNode untaggedNode = new RadTreeNode(GetLocalResourceObject("res_untagged").ToString(), ""); 
        
                        untaggedNode.AllowDrag = true; 
        
                        untaggedNode.Checkable = true; 
        
                        RadTreeView1.Nodes.Add(untaggedNode); 
        
                        uxTreeAssessments.DataSource = new NHibernateDaoFactory().GetAssessmentDao().GetAll(); 
        
                        uxTreeAssessments.DataFieldID = "ID"; 
        
                        uxTreeAssessments.DataValueField = "ID"; 
        
                        uxTreeAssessments.DataTextField = "LocalizedName"; 
        
                        uxTreeAssessments.DataBind(); 
        
                    } 
        
                }

And then the nodedatabound:

    
            protected void uxTreeAssessments_NodeDataBound(object sender, Telerik.Web.UI.RadTreeNodeEventArgs e) { 
        
                    if (e.Node.Level == 0) { 
        
                        Assessment a = e.Node.DataItem as Assessment; 
        
                        foreach (Folder f in a.Folders) { 
        
                            RadTreeNode n = new RadTreeNode( 
        
                                string.Format("{0} ({1})", f.LocalizedName, f.Questions.Count), 
        
                                f.ID.ToString()); 
        
                            n.DataItem = f; 
        
                            e.Node.Nodes.Add(n); 
        
                        } 
        
                    } else if (e.Node.Level > 0) { 
        
                        Folder parent = e.Node.DataItem as Folder; 
        
                        foreach (Folder f in parent.Folders) { 
        
                            RadTreeNode n = new RadTreeNode( 
        
                                string.Format("{0} ({1})", f.LocalizedName, f.Questions.Count), 
        
                                f.ID.ToString()); 
        
                            n.DataItem = f; 
        
                            e.Node.Nodes.Add(n); 
        
                        } 
        
                    } 
        
                }

The problem is that the ELSE IF part is never called ... and thus the sub folders of the folders are not rendered.

Any assistance would be appreciated as I am stuck here.. Not even sure if the approach is correct.
Thanks!!
