I have a MenuFlyout in my App.xaml: <Application.Resources> <MenuFlyout x:Key="LessonFlyout"> <MenuFlyoutItem Text="Edit"/> <MenuFlyoutItem Text="Delete"/> </MenuFlyout> </Application.Resources> And I wanted to give MenuFlyoutItem click event but the compiler says I can't do this. But I need a click event so I searched and found out that I can bind command to MenuFlyoutItem. My MenuFlyout will be attached to a different objects in different pages. For example: StackPanel thisSender = sender as StackPanel; FlyoutBase.SetAttachedFlyout(thisSender, Application.Current.Resources["LessonFlyout"] as

I'd like to design a Swing button that would look like an UWP one – like so [Windows Settings App]: This is what I have so far: using the following code: Font f = new Font("Segoe UI", Font.PLAIN, 20); Color gray = new Color(204, 204, 204); button.setFont(f); button.setBackground(gray); button.setContentAreaFilled(false); button.setFocusPainted(false); button.setFocusable(false); button.setForeground(Color.BLACK); button.setBorder(BorderFactory.createEmptyBorder(10, 14, 10, 14)); The background color cannot be changed at all, regardless whether button.setContentAreaFilled(Boolean b); property

Here is my code: public sealed partial class MainPage : Page { InkCanvas[] arrInkCanvas = null; public MainPage() { this.InitializeComponent(); int i = 0; arrInkCanvas = new InkCanvas[1000]; try { for (i = 0; i < 1000; i++) { arrInkCanvas[i] = new InkCanvas(); } } catch (Exception ex) { } } } When i run this code in WPF app there's no problem , but in UWP it throws exception : "Insufficient memory to continue the execution of the program." Is it bugs or something can anyone tells me ? Thanks. Windows OS will balance the memory located to the application based on RAM and OS configuration. You

I edited a ScrollViewer 's template to wait only 0.5 seconds before hiding the scrollbars, and this succeeds in hiding them at that time, but they reappear for another 0.5 seconds. Why? To reproduce, create a page resource for a ScrollViewer's Style with the default Template ( find it here on MSDN ) and change the 3 occurances of "3" to "0.5". Then use the following XAML: <Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}"> <ScrollViewer Height="500" Width="500" Style="{StaticResource ScrollViewerControlTemplate1}"> <Grid Background="Blue" Height="1000" Width="1000"> </Grid>

My first thought was to use GetPackageFamilyName() and look for ERROR_SUCCESS vs APPMODEL_ERROR_NO_PACKAGE . But, I need to support Windows 7, which makes GetPackageFamilyName() unusable. Is there a decent alternative method? Anything in the Registry, perhaps? Use GetProcAddress() to load GetPackageFamilyName() dynamically at runtime, eg: typedef LONG WINAPI (*LPFN_GPFN)(HANDLE, UINT32*, PWSTR); bool bIsUWP = false; LPFN_GPFN lpGetPackageFamilyName = (LPFN_GPFN) GetProcAddress(GetModuleHandle(TEXT("kernel32")), "GetPackageFamilyName"); if (lpGetPackageFamilyName) { UINT32 size = 0; if

I have this listview: <Page x:Class="DataBase.ControlsPage" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" DataContext="{Binding CustomersViewModel, Source={StaticResource ViewModelLocator}}"> <Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}"> <ListView Name="HeaderList" ItemsSource="{Binding Customers}"> <ListView.ItemTemplate> <DataTemplate> <Grid> <Border Background="Bisque"> <TextBlock Text="{Binding Name"/> </Border> <ListView Name="SubItemsList" ItemsSource="{Binding Project}" ItemClick=

I'd like to do something like this is a Style: Value="{x:Bind MyCustomDependencyProp, RelativeSource={RelativeSource TemplatedParent}}" Is that possible? Are there any performance benefits? Using TemplateBinding does not seem to work, with a custom DependencyProperty as described elsewhere here on SO: https://stackoverflow.com/a/8657453 RelativeSource (with x:Bind) is not supported, therefore this particular scenario won't be possible (at the moment, at least). Using TemplateBinding or standard Binding to TemplatedParent (as you mentioned) are workarounds. TemplateBinding is already an

When I use Storyboard to zoom in TextBlock it pixelates while zooming and rerenders only on complete. <DoubleAnimationUsingKeyFrames Storyboard.TargetName="TextBlock" Storyboard.TargetProperty="(UIElement.RenderTransform).(CompositeTransform.ScaleY)"> <EasingDoubleKeyFrame KeyTime="0:0:0.5" Value="1.5"/> Is there a way the TextBlock is rerendered each frame? I found a solution though it's not about TextBlock anymore but for me it worked: private void CreateText(string text) { _compositor = ElementCompositionPreview.GetElementVisual(this).Compositor; CreateDevice(); _spriteTextVisual =

I'm looking for a way to edit the DatePickerFlyoutPresenter scroll box style. I want to change the text to white the arrow buttons and change the pointover colors but cant seem to find it. could it be useing flipview style? I am using xaml/C# http://puu.sh/lKvcW/a921089600.png From the Live Visual Tree of Visual Studio, we can find DatePickerFlyoutPresenter use LoopingSelector in it. So to change the color of the text in arrow button, we can change the template of Windows.UI.Xaml.Controls.Primitives.LoopingSelector , and we can find it in generic.xaml which typical in C:\Program Files (x86)
