win-universal-app

I am building a Windows Store App / Universal App targeting Windows 8.1 and Windows 10 and I would like to be able to drag and drop items between ListViews and be able to position the item in a specific spot in the ListView. The main problem I'm having is that I can't find a good way to determine the list index of where the item was dropped. I found a sample ( XAML ListView reorder ) but an important difference is that the items in my list have variable heights so the simple calculation this sample project uses to infer the index won't work for me. I am able to get the x,y position of where

Let me start by saying that I'm brand new to UWP and the closest I have come to this language would be C++ about 12 years ago! I'm writing an app for Windows Universal and in it I'll be reading different text files in line by line, split the contents of each line (Some files I won't need to split the line), add the data into a list and then show it on screen. I've tried many ways to do this but I haven't got it working correctly. I currently have two methods that are working, but not consistently. It will show the data but only sometimes. When I run the app (either in emulator or on local

How can I check which platform (Windows / Windows Phone) my app is running? VersionInfo | versionInfo property should helps to check the platform information. var str = Windows.System.Profile.AnalyticsInfo.VersionInfo.DeviceFamily; if (str == "Windows.Desktop") { //... } else if (str == "Windows.Mobile") { //... } Yes, you can use the compiler directives #if WINDOWS_PHONE //some code #endif #if WINDOWS //some code #endif 来源： https://stackoverflow.com/questions/32404755/check-platform-on-windows-10-universal-app

Windows 10 automatically applies a scale factor to UWP apps, to give a similar effective pixel size across multiple devices. I want my UWP UI to look the same across any screen of the same resolution, regardless of the scale factor. Is this possible? For instance, when running my app on the Hololens it applies a 150% scale factor. This means the UI looks squished when compare to a desktop screen of a similar resolution (1280x720). A suggestion ( How to disable auto-scaling on UWP mobile ) says to use TrySetDisableLayoutScaling on the ApplicationViewScaling Class . But this doesn't work. The

I have a Universal App that I'm sideloading in Windows10. I would like to create a script (Powershell, VBS, batch, etc) to pin it to the Start Menu. I have found many examples of how to write a script that pins a desktop application (like this one: https://gallery.technet.microsoft.com/scriptcenter/Script-to-pin-items-to-51be533c ). I've tried using the script to pin the actual App .exe file located in C:\Program Files\WindowsApps... but that doesn't work. When I try and pin that way, I run DoIt(), which doesn't return anything. There are no error messages, but the tile is not pinned to the

My requirement: when tapped on the border in ListViewItem(DataTemplate) an overlay should appear on top of it with animation. In my listview data template I defined a visual state at the root. I want to goto the visual state when user taps on the border. I have tried following xaml but it is not working <DataTemplate x:Key="MyTemplate"> <Grid Background="{Binding ItemBackground}" Margin="0,0,0,5" Height="auto"> <VisualStateManager.VisualStateGroups> <VisualStateGroup > <VisualState x:Name="OverlayState"> <Storyboard > <DoubleAnimation Storyboard.TargetName="checkedBorder" Storyboard

I am developing UWP application. I have a database that should be initialized with about 20,000 records. The records, that are defined as follows: private static readonly ObservableCollection<TickRecord> TickRecords = new ObservableCollection<TickRecord>(); I tried to insert the records one at a time like this: private void CreateFakeTickRecords() { if ( Database.Database.CountTickRecords() > 0 ) { return; } foreach ( var tickRecord in TickRecords ) { Database.Database.AddOrUpdateTickRecord( tickRecord ); } } and public static void AddOrUpdateTickRecord( TickRecord tickRecord ) { // Create a
