Reflection

A feature I use heavily in Umbraco, and one I've missed in EPiServer CMS, is the use of icons for different page types in the tree. Although this functionality has been around for a while using PageTreeIcons, when using PageTypeBuilder it can be quite cumbersome to maintain a configuration with PageTypeId's, when we want to move away from that.

Heavily inspired (and with some borrowing), I've converted the PageTreeIcons project to a collection of attributes that you can use to alter the icons for page types and properties. It's still an early draft, but it works.

This way, it's really easy to keep track of the icons for your properties, and there's no need to keep an extra section in your web.config. Some features have been removed, since EPiServer CMS 6 already contains some of the functionality (i.e the PageLinkTypeHandler).

It's applied like this, on page types

[PageTypeIcon("~/UI/Images/PageTreeIcons/page.png", typeof(ContentPage))]
[PageType(AvailablePageTypes = new[] { typeof(ContentPage) },
   Filename = "~/UI/Pages/ContentPage.aspx",
   SortOrder = 20,
   Name = "[Public] ContentPage",
   DefaultSortIndex = 100,
   Description = "An ordinary content page.")]
public class ContentPage : PageTypeBuilder.TypedPageData { ... }

and like this, on a property

[PropertyEmptyIcon("~/UI/Images/PageTreeIcons/warning.png", 
   "/pagetreeicons/property/missingkeywords", 
   "MetaKeywords", 
   new [] { typeof(BaseModule), typeof(ModuleContainer), typeof(Contact) })]
[PageTypeProperty(EditCaption = "Keywords",
   HelpText = "A comma-separated string containing keywords used for this page.",
   Searchable = true,
   UniqueValuePerLanguage = true,
   Type = typeof(PropertyString),
   SortOrder = 10)]
public virtual string MetaKeywords {
   get;
   set;
}

Again, kudos to Henrik Nyström, http://thisisnothing.wordpress.com/, for writing this in the first place.
