问题 I am writing a little app in C# for windows 10, and I have a listview as below, which is already in a grid. However the grid I am adding to the listview doesn't expand out to fill the space, it is just grows as wide as the length of the data contained in the field bound to it. What am I doing wrong? I don't want to use fixed fields, I'd prefer to use a relative proportion of the page width. Help! <Grid x:Name="RootGrid" Margin="5" > <Grid.RowDefinitions> <RowDefinition Height="Auto"/>

问题 I am writing a simple 2D game engine for UWP. I have a code snippet taken from XNA, checking for if a certain key is pressed (see below), and I'm trying to do something similar. Indeed, in my game engine I'd rather not use the dedicated event handlers (KeyDown etc), but instead simply check for pressed keys in my game loop - if this is possible to do. One reason for this is that I can then control for example how often a bullet fires if the key is continuously pressed (using a timer and mod).

问题 I would like to binding a property defined in code-behind, and another one defined in a class in the same template with datatype. Here's an example: My class: public class MyClass { public string name { get; set; } public MyClass(string name) { this.name=name; } } Code behind: public string name2; public MyView() { this.InitializeComponent(); name2 = "Tim"; } <DataTemplate x:Key="MasterListViewItemTemplate" x:DataType="model:MyClass"> <StackPanel> <TextBlock Text="{x:Bind name}"/> <TextBlock

问题 Can the new InkCanvas and InkToolbar (see this link) be used in Windows 10 UWP HTML5/JS apps? I see only C#, C++, and VB tabs in the documentation. This is in the documentation under XAML controls, which to my understanding is not part of the HTML support. Is there an alternative/complementary HTML5/JS tool set for these components? Thanks! 回答1: The types InkCanvas and InkToolbar are currently not supported in UWP HTML5/JS. For HTML5/JS, you can use this official sample as reference. There

问题 I was trying to define a Windows Runtime type in IDL, and consume its projected type. Going from a default-generated Blank App UWP project (called "Blank App" ), I added "MyControl.idl" : namespace BlankApp { [default_interface] runtimeclass MyControl : Windows.UI.Xaml.Controls.Control { MyControl(); } } Compiled the solution, then copied MyControl.h and MyControl.cpp from Generated Files/sources to the project root directory. I included the header for the projected type and added the

问题 I have two models that i want to represent as directories and files. The models both implement an interface which contains a property string Name {get;} . public interface INode { string Name { get; } string Path { get; } } public class Directory : INode { public Directory(string name, string path) { this.Name = name; this.Path = path; } public string Name { get; } public string Path { get; } } public class File : INode { public File(string name, string path) { this.Name = name; this.Path =
