It’s guaranteed to be synchronous because: The return value of dispatchEvent indicates whether any of the listeners which handled the event called preventDefault. Since the return value indicates whether any of the listeners that handled the event called preventDefault, the method must block (not return) until all of the listeners are done executing, which is … Read more
When getting this error through Visual Studio it was because there was a signing certificate setup to match the computer it was originally developed on. You can check this by going to the project properties > signing tab and checking the certificate details. You can uncheck “Sign the ClickOnce manifests” to disable signing. If you … Read more
This solved my issue: Windows.ApplicationModel.Core.CoreApplication.MainView.CoreWindow.Dispatcher.RunAsync(CoreDispatcherPriority.Normal, () => { // Your UI update code goes here! } ); Correct way to get the CoreDispatcher in a Windows Store app
As far as I can tell, this was caused by a conflict with the version of Python 3.7 that was recently added into the Windows Store. It looks like this added two “stubs” called python.exe and python3.exe into the %USERPROFILE%\AppData\Local\Microsoft\WindowsApps folder, and in my case, this was inserted before my existing Python executable’s entry in … Read more
Try the following: private DependencyObject FindChildControl<T>(DependencyObject control, string ctrlName) { int childNumber = VisualTreeHelper.GetChildrenCount(control); for (int i = 0; i < childNumber; i++) { DependencyObject child = VisualTreeHelper.GetChild(control, i); FrameworkElement fe = child as FrameworkElement; // Not a framework element or is null if (fe == null) return null; if (child is T && fe.Name … Read more
TL;DR; – It preserves data on Isolated Storage when updating from WP8.0 to WP8.1 Runtime. Because the provided link to MSDN says only about Silverlight apps, and it’s not clear (if I hadn’t missed something) what would happen in case: I’ve old WP8.0 Silverlight App and now I decided to upgrade it to WP8.1 Runtime … Read more
Click is there for backwards compatibility, and is essentially the same as Tapped. Tapped is a “high level gesture” that will translate automatically to a click, tap, pen press, etc. and is what I would recommend to use. PointerPressed is not what you want. Here’s why: if I press and hold, the PointerPressed event will … 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
So as a quick example, one way of doing this; <Grid Grid.RowSpan=”2″ x:Name=”TheGrid” Margin=”30,30,0,30″ Visibility=”{Binding IsSearchEnabled, Converter={StaticResource visibilityConverter}}”> <Grid.RowDefinitions> <RowDefinition Height=”60″/> <RowDefinition Height=”*”/> </Grid.RowDefinitions> <!– Start the magic –> <Grid.RenderTransform> <TranslateTransform x:Name=”SlideIn” X=”750″ /> </Grid.RenderTransform> <Grid.Triggers> <EventTrigger RoutedEvent=”Grid.Loaded”> <BeginStoryboard> <Storyboard> <DoubleAnimationUsingKeyFrames Storyboard.TargetName=”SlideIn” Storyboard.TargetProperty=”X”> <SplineDoubleKeyFrame KeyTime=”0:0:1.25″ Value=”0″ /> </DoubleAnimationUsingKeyFrames> <DoubleAnimationUsingKeyFrames Storyboard.TargetName=”TheGrid” Storyboard.TargetProperty=”Opacity”> <SplineDoubleKeyFrame KeyTime=”0:0:1.55″ Value=”1″ /> … Read more
