Just saw that Blendables have extended their portfolio of WPF controls. The stuff looks good, but unfortunately, their licensing scheme doesn’t:
A license is required for each machine utilizing the blendables controls. [...] As we do not offer a deactivation method, if you must reactivate on a new developer machine you are allowed up to 3 [...]

If you have a WPF TreeView control that shows nested data, and you don’t want the user to select nodes that contain child nodes, you can solve this declaratively as TreeViewItem provides all we need:
HasItems dependency property (bool)
Focusable dependency property (bool)
As both properties have the same type, you can use a binding expression (needs inversion [...]

There will be filtering and multi selection support in the next iteration of my WPF TreeView, but based on a request on the Code Project forum, I decided to implement a simple filtering mechanism on the current version.
First of all, you can provide filtering without even touching the control base class by just applying the [...]

Josh Smith, prolific Code Project writer and blogger, has written a great article about MVC (or M-V-poo, as the doctor would say!) and unit testing of WPF apps. The article can be found on Code Project:

This is a simple snippet which helps you to find a specified parent of a given WPF dependency object somewhere in its visual tree:
/// <summary>
/// Finds a parent of a given item on the visual tree.
/// </summary>
/// <typeparam name="T">The type of the queried item.</typeparam>
/// <param name="child">A direct or indirect child of the
/// queried item.</param>
/// <returns>The [...]

Robby Ingebretsen published the source code of his incredibly useful (and beautiful!) Kaxaml on CodePlex. I often prefer Kaxaml over Visual Studio because it combines a bunch of really smart features with a very nice UI that just makes it a pleasure to work with. I’m definitely looking forward to have a peek at its [...]

In all my Windows Forms applications, I usually start with a common base class for forms and controls that provides a bunch of convenience properties, subscribes to common events, handles proper cleanup etc. I also implement an empty virtual InitControl method which can be overridden by deriving controls to initialize themselves.
As you can see in [...]

This is really trivial, but I’ve always used a similar helper class for my WinForms apps, and it was something I immediately missed when starting my first WPF project. So I thought I should share it with you - a simple helper class to display message boxes without having to worry about a lot of [...]

With this WPF progress dialog, you can display a progress window and invoke a method on a background thread with just a few lines of code. Let’s say, you have a worker method called CountTo100, then all you need to get things running is this:
//create a dialog instance
ProgressDialog dlg = new ProgressDialog();
dlg.Owner = this;
dlg.DialogText = [...]
