问题 I come from WPF and I don't know if it's possible to make a ListView to distribute items horizontally, with all the extras like mouse-wheel scrolling (mouse devices) and swiping (touch devices). I've tried this, but it doesn't behave like the vertical one. Example: I cannot scroll with the mouse-wheel. <ListView ScrollViewer.VerticalScrollBarVisibility="Disabled" ScrollViewer.HorizontalScrollBarVisibility="Auto" ItemsSource="{Binding Collection}" > <ListView.ItemsPanel> <ItemsPanelTemplate>

问题 I have been using SQLitePCL (currently ver 3.8.7.2), and now decided to experiment with Delete and Update Cascade by turning on the Foreign Key constraint. I understand this feature is disabled by default and according to SQLite documentation, the constraint must be enabled separately for each database connection . The connection string only takes a database path (for SQLitePCL anyway) and doesn't allow more flexible composite connection string of the form data source=d:\foo\bar\mySqlite.db

问题 In WPF, we can set WindowStyle to None to create a "borderless" window. But, I found that UWP contains pages only. Is there any way to have borderless windows in UWP? 回答1: It's not possible to do the same, however you could make your app go fullscreen or expand its content into title bar so you'll get more place for the content. Another similar thing may be using Picture In Picture mode, but these windows are always above others AFAIK. Read more about fullscreen in UWP for example here, about

问题 As the microsoft iffical said, The UWP can't use system web with aad b2c, has to use Embedded Webviews.

问题 G'day Folks, I feel like I'm can't see something basic. Action is defined as public delegate void Action(). DispatchedHandler is defined as public delegate void DispatchedHandler(). Yet the following code generates at the RunASync line: Error CS1503 Argument 2: cannot convert from 'System.Action' to 'Windows.UI.Core.DispatchedHandler'. public static async Task DispatchToUI(Action action, CoreDispatcherPriority priority = CoreDispatcherPriority.Normal ) { if (CoreApplication.MainView

问题 My UWP app uses app folder ( Files.ReadWrite.AppFolder ) for storing app data on OneDrive. I upgraded the app to use Microsoft Graph SDK instead of the old OneDrive SDK (version 1.x). I didn't get the authentication to work using the old client id registered in https://apps.dev.microsoft.com, so I registered my app in https://aad.portal.azure.com/ and I use MSAL.NET for authentication. The problem is that the upgraded app creates a new app folder on OneDrive ( My App 1 ) instead of using the

问题 How can I bind the ItemsSource of a Combobox column to a collection that is a sub-property of a property on the same row? In other words, the DataGrid is bound to a collection of items of a class the contains Property1 and Property2. So the DataGrid has two columns, Property1 and Property2. Property1 has a sub-property that is an Observable Collection. The column for Property2 is a Combobox column that should use Property1's Observable Collection as its ItemsSource. I'm loading the grid's
