Hiya,
I do not know if DNN is a red herring or not.

I have an IList<CategoryInfo> of items which looks like this

    
             public class CategoryInfo 
        
                { 
        
                    public int ModuleId{get; set;} 
        
                    public int ItemId{get; set;} 
        
                    public int CreatedByUser{get; set;} 
        
                    public string Content { get; set; } 
        
                    public DateTime CreatedDate{get; set;} 
        
                    public string CategoryDescription{ get; set;} 
        
                    public int? ParentId { get; set; } 
        
                }

which I am trying to bind to a treeview using the following.

    
                        var objCategories = new CategoryController(); 
        
                        RadTreeView1.DataSource = objCategories.GetCategories(ModuleId);  
        
                        RadTreeView1.DataTextField = "CategoryDescription"; 
        
                        RadTreeView1.DataValueField = "ItemId"; 
        
                        RadTreeView1.DataFieldParentID = "ParentId"; 
        
                        RadTreeView1.DataBind();

my result set looks like this
ModuleId    itemId      CategoryDescription                                parentId

but when I run the code it returns a flat tree, I am sure I am missing something but I can not fathom it out.

TIA
