One of the great parts about commands in WPF is that they know if they can currently execute or not. When they cannot execute, the control(s) that are set to execute the command will be disabled automatically. For example, if your application has no changed data, the Save toolbar button will automatically be disabled, assuming its Command property is set to the Save command. WPF will automatically ask all of the commands being used in your UI if they can execute. Allowing CommandManager to query your ICommand objects Allowing CommandManager to query your ICommand objects
Refresh / Update WPF controls Refresh / Update WPF controls Sometime in the past, a friend asked me how to update a control to show status while his code is doing a loop of stuff. Essentially changing the text of a label (or sophisticatedly we can say a text-based progress bar). In my past coding with MFC and WinForms, it's fairly easy enough, you just invalidate and do an update (Invalidate / UpdateWindow in MFC or Invalidate / Update in WinForms).

I've been playing around with WPF animation, and ended up wanting to take a snapshot of an animation at a specific place. Specifically, I have a canvas that has some pictures on it that are moving, and I want to be able to save a bitmap of what it looks like at a specific time. Getting the bitmap is pretty easy, using a RenderTargetBitmap and a VisualBrush. private BitmapSource CaptureScreen(Visual target){ Taking snapshots of WPF animation - Eric Gunnerson's Compendium Taking snapshots of WPF animation - Eric Gunnerson's Compendium
Download source - 3.37 Kb etc) --> Introduction Over the past few months I have been creating a variety of WebControls some of which have needed access to a DataSource such as a DataSet in order to work properly.

Building a Perfect WPF Developer Workstation - Tim Sneath Wonderful list of tools needed for any WPF developer. Although, I'd suggest other fonts as well - I find that switching between proggy square, inconsolata, consolas, etc.. gives me a little "boost" every time I switch. And, since you have the words "developer workstation" right in the description (and correct I may add), any chance of nudging the MSDN bean counters and saying "hey, Blend is indeed a developer tool"? Not having it included in MSDN is really, really frustrating to us that already accepted a nice big slap already with the different editions. If so, thanks!

Introduction This article is about developing a XAML only WPF CheckListBox and ListBox with Selection Indicator control styles, and taking the same requirements and building a custom control that takes a very different approach to the problem. This article is about taking a concept and running with it. It's about this developer's desire to recreate a complex control using only XAML markup. We will explore the XAML only approach, then toss everything into a blender, and pour out two WPF Custom Controls using VB.NET.

WPF Enum List Converter Introduction This article demonstrates how to bind a C# enum definition to a WPF ComboBox, which is not as simple as it first seems. The solution was extracted from a real-world commercial application. Background Enum definitions are great for defining small fixed lists of options for a property. They are easy to define in code, and are strongly typed, so they help produce robust code.
