    Using Commands with RadTreeView for WinForms

    Cool top secret features fascinate me. Remember the hidden “Easter eggs” game in Excel 2002 (http://www.j-walk.com/ss/excel/eastereg.htm)? Don’t you love it when developers pull something up from their sleeve, which is so cool, people just brag about it for years? Truth to be told, we have a secret feature in RadTreeView for WinForms as well. It may be not as cool as the “Easter eggs” Excel game, but is something I wanted to share with you for some time now.

    WPF Series: Adorners, Commands and Logical Tree

    Today I'm going to tell you a WPF story. But before I start to dig deeper let me first introduce you the main characters in this post. Here they are: Adorner - adorners are simple UIElement decorators. Suppose that you have a RichTextBox and you want to place a comment box over it, so that users can comment on the text in the box. This can be archived with adorners. Actually the WPF framework uses adorners internally for exactly the same purpose when you edit and annotate FlowDocument in a DocumentViewer. This is the reason why adorners are in System.Windows.Documents namespace. Command - commands are UI...
