问题 I'm working on my first UWP app and I want create a UI like this . For each list item (project) there'll be a set of buttons. For certain list items(projects) some of these buttons will be disabled some times. So I need to disable and change the image for such button in those list items(projects).

问题 I'm currently trying to style a ListView so each of the items inside it can control their own background color, PointerOver, Pressed and Selected states. I have figured out that I can set the Background of the ListViewItem to Transparent and let the DataTemplate for my item control the Background. But what I'm struggling with is the VisualStates of the ListViewItem . They just won't seem to style correctly. What I've tried so far is so far is putting my Binding code for the colors inside the

问题 I have an image processing windows 10 application. I am applying filters on that image and showing it on the image element. This is how I am applyting filter and setting it as a source to MainImage element. ProcessImage processImage = new ProcessImage(sourcePixels, width, height); byte[] blurEffect = processImage.BlurEffect(width, height); WriteableBitmap blurImage = new WriteableBitmap((int)width, (int)height); using (Stream stream = blurImage.PixelBuffer.AsStream()) { await stream

问题 I have a List view which shows the project names and some buttons for each project which do different actions like adding a comment viewing images for that project etc.. Depending on the project some projects will have some of these buttons disabled sometimes. And some buttons will not be visible in some projects. So there are two things I want to achieve using data binding in this code. Depending on some boolean variables of the ProjectModel, I need to change the visibility of the buttons. I

问题 I'm making a custom TextBox for UWP to simplify Win2D outlined text solution, for that I created a UserControl that contains only a canvas on which I'll draw the text. Of course I need some properties, like text, outline thickness and color, etc... I also need some properties that are already exposed by the inherited UserControl like Foreground, FontSize, FontFamily... So far so good, it seems like I won't need to implement each one of those common properties. The problem is that I can't find

问题 I'm developing a new UWP app with the Fluent Design System (Acrylic Background and reveal) but apart from being available on Windows 10 Desktop, I also want to publish the application to Windows 10 Mobile. Does Windows 10 Mobile support the Fluent Design System? Or do I have to develop another application just for Windows 10 Mobile without the Fluent Design System? 回答1: Windows 10 Mobile build 10.0.15063 (Creators Update) supports composition effects as well as in-app acrylic (see How to use

问题 I have a listview containing some item. And I want to expand the item to show detail information when I select one item, what should I do? 回答1: I didn't check the CustomControl carefully which provided by @AVK Naidu, which is good and seems can solve your problem.

Just for example here: <Page.Resources>

问题 I've created a .resw file by following the instructions at https://docs.microsoft.com/en-us/windows/uwp/globalizing/put-ui-strings-into-resources. While the localization works fine at runtime, no text is displayed at design time. The only solution proposed so far seems to only work in windows 8.1 apps: Windows store app ResourceLoader at design time 回答1: The New Method of solution that you have mentioned also works in UWP. And it's more recommended to use Data Binding at design time. The
