• What are the BEST resources for learning WPF & .NET?

  - by dicroce

  I'm a longtime C/C++ Unix guy. I recently started work in a new position that's gonna eventually require C# and WPF (and probably some LINQ). What are the best resources to quickly come up to speed on all these Microsoft technologies? Years ago I read Petzold's book and loved it because it was so complete and by the end I really felt like I knew what I was doing... Is their something equivalent for the .NET world?

  - by Alexandru Bolboaca

  I want to unit test a WPF application and one scenario is to check that data bindings are correct. The simple way to do that would be to create the form, force it to bind to data and then compare the values from the controls with the expected ones. Is there any way to do that?

• How to get a group of toggle buttons to act like radio buttons in WPF?

  - by code-zoop

  I have a group of buttons that should act like toggle buttons, but also as radio buttons where only one button can be selected / pressed down at a current time. It also need to have a state where none of the buttons are selected / pressed down. The behavior will be kind of like Photoshop toolbar, where zero or one of the tools are selected at any time! Any idea how this can be implemented in WPF?

• Is DxScene the "WPF for Delphi"? Anyone used it?

  - by André Mussche

  I am playing with DxScene and VxScene: http://www.ksdev.com/dxscene/index.html It looks very nice and powerful: 3d accelerated vector graphics, cross plaform, nice effects, many 2d GUI controls (vector based), good scaling, transparency, rotating (x, y, z), 3d models, etc. Even with many effects, the CPU stays very low (0%)! http://www.ksdev.com/dxscene/snapshot/screen0.jpeg But can it be seen as a good WPF alternative for Delphi? And does anyone use it instead of normal Delphi VCL?

• WPF binding behaviour different when bound property is declared as interface vs class type?

  - by Jay

  This started with weird behaviour that I thought was tied to my implementation of ToString(), and I asked this question: http://stackoverflow.com/questions/2916068/why-wont-wpf-databindings-show-text-when-tostring-has-a-collaborating-object It turns out to have nothing to do with collaborators and is reproducible. When I bind Label.Content to a property of the DataContext that is declared as an interface type, ToString() is called on the runtime object and the label displays the result. When I bind TextBlock.Text to the same property, ToString() is never called and nothing is displayed. But, if I change the declared property to a concrete implementation of the interface, it works as expected. Is this somehow by design? If so, any idea why? To reproduce: Create a new WPF Application (.NET 3.5 SP1) Add the following classes: public interface IFoo { string foo_part1 { get; set; } string foo_part2 { get; set; } } public class Foo : IFoo { public string foo_part1 { get; set; } public string foo_part2 { get; set; } public override string ToString() { return foo_part1 + " - " + foo_part2; } } public class Bar { public IFoo foo { get { return new Foo {foo_part1 = "first", foo_part2 = "second"}; } } } Set the XAML of Window1 to: <Window x:Class="WpfApplication1.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Window1" Height="300" Width="300"> <StackPanel> <Label Content="{Binding foo, Mode=Default}"/> <TextBlock Text="{Binding foo, Mode=Default}"/> </StackPanel> </Window> in Window1.xaml.cs: public partial class Window1 : Window { public Window1() { InitializeComponent(); DataContext = new Bar(); } } When you run this application, you'll see the text only once (at the top, in the label). If you change the type of foo property on Bar class to Foo (instead of IFoo) and run the application again, you'll see the text in both controls.

• How can I speed up the rendering of my WPF ListBox?

  - by Justin Bozonier

  I have a WPF ListBox control (view code) and I am keeping maybe like 100-200 items in it. Every time the ObservableCollection it is bound to changes though it takes it a split second to update and it freezes the whole UI. Is there a way to add elements incrementally or something I can do to improve the performance of this control?

• How to deal with JavaScript when trying to fetch web page in C#.NET/WPF?

  - by Jeff Dahmer

  The .NET WebClient class is nice and all, but it doesn't parse the JavaScript in the page. What I mean is, sometimes a page is forwarded to a different page via JavaScript, or sometimes DOM elements get added to the page via JavaScript with an onload event. I need to deal with both of these situations. What can I do to deal with this? I'm using WPF if that matters.
