Hi,
I've got a complex hierarchy and I'd like to see if it's possible to use the tree control to model it without having to program a bunch of code.

I've got a class, call it "foo". A "foo" can have a collection of "foo"s, as well as collections of "bar"s and "whatsit"s. I'd like to get the tree to model a foo as follows:

  • Foo 1
    • Foos
      • Foo 3
        • Foos
        • Bars
          • Bar
          • Bar
        • Whatsits
    • Bars
      • Bar
      • Bar
    • Whatsits
      • Whatsit
      • Whatsit
  • Foo 2
    • Foos
      • Foo 4
        • Foos
        • Bars
        • Whatsits
    • Bars
      • Bar
    • Whatsits
      • Whatsit

So basically, anytime I bind an item of type "foo", it needs to bind with 3 child nodes (foos, bars & whatsits). Expanding a foo node should repeat the heirarchy; expanding a bar or whatsit node gets me the collection of those items.

Thanks!

Hello Jon Barron,

Attached is a sample project, could you please review it and tell me if it works for you. If you want to make a different template for each item you should review this article. I will be glad to further assist you if you need so.

On a side note, I'd like to inform you that we've just released an online tool that allows you to reduce the size of your Silverlight applications. For more information, please visit http://blogs.telerik.com/blogs/posts/10-06-10/telerik_assembly_minifier.aspx
