VisualStateManager on Flyout not highlighting entire area

由 半世苍凉 提交于 2019-12-08 14:23:26
问题 I have a VisualStateManager that controls the background color when the pointer is over the item. The problem is, it doesn't highlight the entire area, just a small portion around the text and icon. Here's my code: Not fully highlighted <FlyoutBase.AttachedFlyout> <MenuFlyout> <MenuFlyoutItem Text="Delete" Click="DeleteMenuItemClick"> <MenuFlyoutItem.Template> <ControlTemplate TargetType="MenuFlyoutItem"> <Grid> <StackPanel Orientation="Horizontal" Padding="0"> <SymbolIcon Symbol="Delete"

Win RT Xaml GridView: Drag select multiple items

由 ⅰ亾dé卋堺 提交于 2019-12-08 13:45:30
I'm trying to select multiple items in a GridView by hovering over them with pressed mouse (like drawing). I tried to achieve this with the PointerEntered event but I'm unable to change the selction from code. Is there a way to implement a custom selection mode? This didn't work for me because I can't use Style.Triggers in Win RT XAML: https://stackoverflow.com/a/2886223/5739170 You will have to inherit the gridview control and override the PrepareContainerForItemOverride method: The code: public class MyGridView : GridView { protected override void PrepareContainerForItemOverride

Windows 10 Universal app screen size on launch not working

由 自闭症网瘾萝莉.ら 提交于 2019-12-08 12:17:53
问题 I had read a ton about setting the app window size on launch. Basically, my app is launching full screen everytime. I want to restrict it to a pre-defined size when it launches. However, nothing seems to be working. Here is what I have done so far: I have put the following: var desiredSize = new Size(400, 600); ApplicationView.GetForCurrentView().ExitFullScreenMode(); ApplicationView.GetForCurrentView().SetPreferredMinSize(desiredSize); ApplicationView.PreferredLaunchViewSize = desiredSize;

由 落爺英雄遲暮 提交于 2019-12-08 11:37:19

So I need something like regions from Prism 5.0 in the Windows-Store-App-Prism framework. A similar problem was already solved: Register Navigation Service to Frame Element and NOT the page - WinRt Prism 2.0 but I don't like this

Implement UI virtualization in custom ItemsPanel

由 99封情书 提交于 2019-12-08 08:10:28
问题 My goal is to display some layout like the official Android Imgur app where items have fixed width but variable height. I already have a custom panel with a GridView . It works. However, it breaks a couple of things: I don't get UI virtualization. This is a big performance bottleneck when lots of images need to be rendered. Since virtualization is gone, incremental loading isn't supported either. I've searched around a lot, but I couldn't find any documentation on how to implement
