UWP 带左右滚动按钮的横向ListView———仿NetFlix首页河的设计

1. 需求 也是之前写的控件了，模仿NetFlix的河的设计。 大体要求如下： 1. 横向的ListView 2. 左右按钮，可以左右移动河卡片，左右的滚动条不可见 3. 左右按钮仅在鼠标Hover事件中可见 大家可以看下NetFlix uwp版，国内爱奇艺也是这样设计的，芒果TV之前是，但是新版去掉了这种风格。 其实我也是一个菜鸟，一开始纠结怎么写这个控件，怎么传递ItemsSource，而且还在SO上发起了提问 How to customize a horizontal listview with left/right button on uwp? 很遗憾，uwp几乎灭绝，没有人回答我的问题。于是各种寻找，终于发现了大神 Pieter Nijs 写的文章 https://blog.pieeatingninjas.be/2016/01/17/custom-uwp-control-step-through-listview/ 大神的需求和我的类似，见图 于是膜拜文章，写下了适合我自己的控件见图： 2. 实现 👌好了，下面开始撸代码，先新建一个用户控件，名字叫 StepThroughListView ，看看Xaml的布局， <Grid> <ListView x:Name="ListViewRiver" HorizontalAlignment="Stretch"

问题 I've build this example to show my issue. I need to create a hierarchy to be shown in a treeview, treeview to be bound to the view model. In the good old days of VB6 I would have used DoEvents to unlock the UI but here I'm not able to understand how to proceed. On VS19 create a blank UWP project and call TestLoadSync it then copy paste this in the files: App.xaml.cs using System; using System.Collections.Generic; using System.IO; using System.Linq; using System.Runtime.InteropServices

I'm trying to figure out, if it is possible send using Windows.Media.SpeechRecognition; args.Result.Text as parameter from UWP to Console application. For example by following scenario I'm sending TextToSpeech(args.Result.Text); with args.Result.Text; value, where using Windows.Media.SpeechSynthesis; text-to-speech pronounces the recognition result each time when args.Result.Text; appears. textBlock2.Text = args.Result.Text; also displays result: private async void ContinuousRecognitionSession_ResultGenerated( SpeechContinuousRecognitionSession sender,

So I have a Windows Universal Class Library that has a resource dictionary in it that I want to merge with my Windows 10 Universal Application's main resource dictionary in App.xaml.

UWP VisualStateManager PointerOver does not work

由 冷暖自知 提交于 2019-12-04 05:34:39
问题 I am mimicking the behavior of Groove Music, which displays a drop shadow effect when mouse hovers on an album cover (in my code it's the entire DataTemplate). But My VisualStateManager doesn't seem to work. Any ideas? I have implemented that programmatically but I want to use xaml to do that for practice. ---Update--- Changing Stackpanel to Grid still doesn't make things work. <GridView Grid.Row="1" Margin="10" IsItemClickEnabled="True" ItemsSource="{x:Bind Albums}"> <GridView.ItemTemplate>
