  • 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 -.

  • WPF Data Providers
    One of the nifty new features of the WPF platform is the pluggable data providers. Data binding in WPF is extremely powerful -- I am constantly amazed at how much procedural code you can dump in favor of markup with creative bindings. Tags: NET;Code;WPF It ships with two out of the box: ObjectDataProvider: allows you to execute binding expressions against an object and it's methods. XmlDataProvider: loads an XML data source and makes it available as a binding source. State, Age, Income. We can get the data loaded into a collection source through the XmlDataProvider.

  • 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!

  • 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

  • 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.

  • Using Model – View – ViewModel with Silverlight
    have found it extremely easy to use when developing very different applications and have used the design pattern recently in both ASP.NET, WPF and Silverlight applications. Josh Smith did an excellent screen cast for Pixel8 on using MVVM with WPF, you can find it here. Tags: NET DevCenter WPF Silverlight The View – Model – ViewModel design pattern, also known as MVVM, is getting more popular these days. However easy as it might be is seems to confuse people as I have seen some terrible examples where people make a complete mess of things. 11: {. 13: set. 14: {. 19: }.

  • 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.
