Once the edit behavior is enabled, you can start the editing process by selecting the item and pressing the F2 key.The edit process can be started programmatically (in the code-behind). Sheriff is a Business Solutions Architect with Fairway Technologies, Inc. There are many examples of using the Windows Presentation Foundataion (WPF) Tree View that you can find on the Web, however, most of them only show you how to go to two levels. This is where it’s vital to understand exactly how the Hierarchical Data Templates work.Fairway Technologies is a premier provider of expert technology consulting and software development services, helping leading firms convert requirements into top-quality results. In this article, I’m going to break down how these templates work, so you can really understand what’s going on underneath the hood.This method discards modifications to data since the last save.The Preview Edit Started event occurs when the treeview item is about to be edited.What’s important is how you structure the classes into which your data will be placed.Just as a Tree View is a hierarchical structure, create a set of classes that is also a hierarchy. A constructor is created to accept a “name” argument that you can use to set the Name property when you create an Employee object. First is a string property, called Description, which holds the name of the employee type, such as “Supervisor” or “Project Manager.” The second property, Employees, is a generic collection property to hold a list of Employee objects that are associated with this particular employee type.

You don’t want to use hard-coded XAML in your WPF application.This complacency was shaken when recently I was asked if it was possible to use Dynamic Data to convert a flat observable data stream to a fully hierarchical structure.I immediately replied yes of course without weighing up in advance what the solution could be.For this post I assume familiarity with Dynamic Data or at least familiarity with some of my previous posts, so for those of you who are not already familiar with dynamic data see What is dynamic data? Dynamic data has evolved over several years where each new operator has been created to overcome a necessity for a practical problem which I have been working on.It is so functionally rich I always assume that there is not a lot that it cannot do.
