  • WPF MVVM Helper Library (WPF + MVVM = testability)
    There's been a lot of talk about the Model-View-ViewModel pattern recently and it's usage around the WPF and Silverlight technology stack. When teaching WPF, I always introduce students to MVVM as part of the Essential WPF class, it's an incredibly useful pattern that really separates the UI from the code behind behavior. It's evolution owes a lot to various blog posts, WPF Disciples, and other WPF leaders; I certainly didn't invent anything radically new but borrowed heavily from all kinds of places as I built various classes I needed for my own work. file -.

  • Part 2: Changing WPF focus in code
    In the last post , I wrote about how focus is generally managed in WPF - we have focus scopes to track a single element within that scope for logical focus, and then one of those elements is given physical, or keyboard focus. First, there is a Keyboard class in WPF which exposes several methods and properties. However, the most common request is to set initial focus to a specific control - remember that WPF doesn't do that by default. However, a popular way to develop WPF applications is to separate out chunks of UI into separate UserControls. Tags: NET WPF

  • Part 3: Shifting focus to the first available element in WPF
    We've seen how to programatically control focus and that's all great stuff, but one thing I like to do with WPF is see how much of the repetitive or UI-specific code I can move into the XAML and keep out of the code behind. Tags: NET WPF We can use the FocusManager.FocusedElement property to shift focus in XAML but it only works when the element exists in the main XAML file. If you use UserControls it turns out that the approach doesn't work because that element is loaded separately and not available when the initial focus is being determined. but all is not lost!

  • MVVM: Views and ViewModels
    Views are the UI presentation of data - in the case of a WPF/Silverlight application this is most commonly the XAML and XAML code behind files (they are considered a single element together). That way, my ViewModel sticks with base (non-WPF) types. This is necessary under WPF 3.5 Tags: NET Code MVVM WPF In the previous post, I provided a link to the project template you can use to start a new MVVM project using the JulMar MVVM library. Here's the two links in case you didn't get them before: MVVM Helpers Distribution. Project Template. Dependencies. ViewModels.

  • Adding to an ObservableCollection from a background thread
    found a solution from Tamir Khason (a fellow WPF disciple), he wrote a thread-safe version ( [link] ), but I didn't want to add the locking into the collection itself (I want to manage it at a higher level myself). Tags: NET WPF One annoying thing about ObservableCollection is that it doesn't support modifications from background threads. ran into this problem a while back and searched out to see if someone else had solved it. Really, all I want is to do the notification on the proper (Dispatcher) thread. ObservableCollection. {. var eh = CollectionChanged; if (eh ! null ). {.

  • Simple MVVM Toolkit: Feature Rich with WPF and WP7 Support
    On top of all that I’ve also added support for both WPF ( Windows Presentation Foundation ) and WP7 ( Windows Phone ). Technical MEF MVVM Silverlight WP7 WPFI’ve rounded out the feature set of my Simple MVVM Toolkit to include a Message Bus (also known as an event aggregator or mediator ) for loosely coupled communication among view-models and to support MEF (Managed Extensibility Framework0 for dependency injection (also known as inversion of control) of service agents to better enable unit testing of view-models. ve also updated the online documentation to cover these features.

  • Rehosting the Workflow Designer in WF4
    Both these properties point to ready to use WPF UIElement’s so, as long as the host used WPF, adding them to a form is easy. The toolbox on the left if another standard WPF control called the ToolboxControl. Again easy to add to any WPF form. Tags: NET Workflow WPF WF4 VS2010 Beta2 Note: This blog post is written using the.NET framework 4.0 Beta 2 With Windows Workflow Foundation 3 it was possible to rehost the workflow designer in your own application. But possible is about all there was to say about it as it was pretty hard to do anything beyond the basics.
