<telerik:RadTreeView HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Name="CategoryTree" ItemsSource="{Binding Path=Categories}" SelectedItem="{Binding Path=CurrentCategory, Mode=TwoWay}" SelectionChanged="CategoryTree_SelectionChanged">
                                <telerik:RadTreeView.ItemTemplate>
                                    <HierarchicalDataTemplate ItemsSource="{Binding Categories}">
                                        <TextBlock Text="{Binding Name}" />
                                    </HierarchicalDataTemplate>
                                </telerik:RadTreeView.ItemTemplate>
                            </telerik:RadTreeView>

protected override void Load()
        {
            _categories = new ObservableCollection<CategoryBO>();
            foreach (Category category in _repositoryCategory.Entities.Where(p => p.ParentCategory == null))
            {
                CategoryBO tempCategory = category;
                if (tempCategory != null)
                {
                    Categories.Add(tempCategory);
                }
            } 
            _categoryView = CollectionViewSource.GetDefaultView(Categories);
            OnPropertyChanged("CategoriesList");
            OnPropertyChanged("CurrentCategory");
        }

and this is how I initialize a CategoryBO object:

 public static implicit operator CategoryBO(Category category)
        {
            return new CategoryBO(category);
        }
public CategoryBO(Category category)
        {
            ID = category.CategoryID;
            ParentID = category.ParentID;
            Name = category.Name;
            foreach (ProductBO product in category.Products)
            {
                _products.Add(product);
            }
 
            foreach (Category cat in category.Categories)
            {
                _categories.Add(cat);
            }
        }

• Have the spell checker work when columns are auto-generated (just apply it to all columns)

• Programmatically add columns to the gridview (MVVM pattern) by using reflection on an object.  With any luck, I would be able to use a custom DataAnnotation to indicate whether to use spell check on the generated column.  Also could maybe use a different annotation for the column heading??
