DataTrigger is not currently supported in WinRT XAML. Addendum by Mike Brown The DataTrigger API has been replaced with the VisualStateManager a similar API to Data Triggers was provided by the Blend SDK for Silverlight. Since the Attached Behavior Pattern works in WinRT, it is possible to do the same.
According to the accepted answer in this post, there is no other way at the moment. However, the File IO team is considering changing the the api so that it returns null instead of throwing an exception. Quote from the linked post: Currently the only way to check if a file exists is to catch … Read more
Because there was no solution to this problem, I had to reimplement all paging relevant classes: Page, Frame, SuspensionManager, etc… The solution can be downloaded here: https://github.com/MyToolkit/MyToolkit/wiki/Paging-Overview Update: The page class now also provides the OnNavigatingFromAsync method to show for example an async popup and cancel navigation if required…
That is the complete solution for Windows Desktop: Add the Extension reference “Windows Desktop Extensions for the UWP” like Peter Torr – MSFT mentioned. Use this Code to get the HardwareId: using System; using Windows.Security.ExchangeActiveSyncProvisioning; using Windows.System.Profile; namespace Tobit.Software.Device { public sealed class DeviceInfo { private static DeviceInfo _Instance; public static DeviceInfo Instance { get … Read more
This is the preferred way: Windows.ApplicationModel.Core.CoreApplication.MainView.CoreWindow.Dispatcher.RunAsync(CoreDispatcherPriority.Normal, () => { // Your UI update code goes here! }); The advantage this has is that it gets the main CoreApplicationView and so is always available. More details here. There are two alternatives which you could use. First alternative Windows.ApplicationModel.Core.CoreApplication.GetCurrentView().CoreWindow.Dispatcher This gets the active view for the app, … Read more
To improve the other answers even a bit more, the following code also takes care of scaling factors, e.g. for my 200% for my Windows display (correctly returns 3200×1800) and 300% of the Lumia 930 (1920×1080). var bounds = ApplicationView.GetForCurrentView().VisibleBounds; var scaleFactor = DisplayInformation.GetForCurrentView().RawPixelsPerViewPixel; var size = new Size(bounds.Width*scaleFactor, bounds.Height*scaleFactor); As stated in the other … Read more
Sure, here you go. First, you can resize the WebView to the actual content. Then, you scale the WebView back to the original size. It would require a script invoke and a ScaleTransform. Pretty simple, really. Like this: <Grid Background=”{StaticResource ApplicationPageBackgroundThemeBrush}”> <WebView x:Name=”MyWebView” Source=”http://www.stackoverflow.com” /> </Grid> void MyWebView_LoadCompleted(object sender, NavigationEventArgs e) { var _Original = … Read more
You probably don’t want to call Task.Result, for a couple of reasons. Firstly, as I explain in detail on my blog, you can deadlock unless your async code is has been written using ConfigureAwait everywhere. Secondly, you probably don’t want to (synchronously) block your UI; it would be better to temporarily show a “loading…” or … Read more
A later answer, but because no one gave this solution… If you do not want to set the header on the HttpClient instance by adding it to the DefaultRequestHeaders, you could set headers per request. But you will be obliged to use the SendAsync() method. This is the right solution if you want to reuse … Read more
Okay I found a quick solution, define a IAsyncOperation class varialble IAsyncOperation<IUICommand> asyncCommand = null; and set it to the ShowAsync method of MessageDialog asyncCommand = msg.ShowAsync(); In the command handler for retry/try again check if asyncCommand is not null and cancel the last operation if necessary if(asyncCommand != null) { asyncCommand.Cancel(); } Please let … Read more
