问题 I want a layout where a ListBox is placed at the top of the window and a button is attached to the bottom of the ListBox. When the window is too small I want the ListBox to scroll and the button to be visible. When the window is too large, i.e. enough space for all controls and all list items, I want the ListBox to take up exactly as much space as it needs, and empty space be added below the button. I have tried DockPanel: <Window x:Class="WpfApplication1.MainWindow" xmlns="http://schemas

问题 I have two modules in my app, and want to register types for a second module in a separate container. Didn't find any ways to do that. Only way I see now is add prefixes to reusable types like that: var foo1 = new Foo("FOO 1"); parentContainer.RegisterInstance<IFoo>("Foo1", foo1); var foo2 = new Foo("FOO 2"); parentContainer.RegisterInstance<IFoo>("Foo2", foo2); parentContainer.RegisterType<IService1, Service1>(new ContainerControlledLifetimeManager(), new InjectionConstructor(new

问题 EDIT: Looks like this was related to the way I declared the color - using hex value seems to bring it through fine. EDIT: This about referencing from the App.xaml file. The color itself works fine if declared as a local resource. I've created a colour: <SolidColorBrush x:Key="TestBlue"> <SolidColorBrush.Color> <Color R="0" G="86" B="45"/> </SolidColorBrush.Color> </SolidColorBrush> and placed it in a ResourceDictionary. I've then referenced it in a MergedDictionary: <Application.Resources>

问题 I have a WPF window that uses multiple viewmodel objects as its DataContext. The window has a control that binds to a property that exists only in some of the viewmodel objects. How can I bind to the property if it exists (and only if it exists). I am aware of the following question/answer: MVVM - hiding a control when bound property is not present. This works, but gives me a warning. Can it be done without the warning? Thanks! Some example code: Xaml: <Window x:Class="WpfApplication1

问题 I have a page.xaml with a listview. The background color of the page is white and when I tap a ListView item, the background of this item is gray.

问题 I have class public class Car { [Description("name of the car")] public string Name { get; set; } [Description("age of the car")] public int Age { get; set; } } is there any possibility to bind Description attribute to Label content. The solution what I'm looking for shouldn't require to instantiate Class object. 回答1: It won't be a proper binding (which is not necessary for static data anyway) but you can easily create a MarkupExtension to retrieve it, just pass the type and the property name
