问题 I want to make a simple drawing app for children with C# for WinRT. The user can choose a picture and draw a little bit. But how can I save the image (together with the background)? There is no functionality to save the image with background. 回答1: I tried to use your library to render a Canvas into an image file but I got this error runtime: "Can't find component. (Exception from HRESULT: 0x88982F50)". Code looks like this: //SAVE private async void saveButton_Click(object sender,

问题 I've attempted to have a <Grid/> (with interactive stuff inside, not just an image) clipped with rounded corners (a <Border/> or a <Rectangle/> , whatever works). I've attempted multiple solutions, but none of them was compatible with a Windows Store App. No brush: RadialGradientBrush is not supported in a Windows App project. DrawingBrush is not supported in a Windows App project. The type 'VisualBrush' was not found. Verify that you are not missing an assembly reference and that all

问题 I have this XAML to display a ListView in a C++/CX code.

问题 I'm making a Windows Store app in C# and I have a normal TextBlock with a link inside it. And all I want to do it to make the cursor change into a hand when it goes over the text block, but unlike in WPF applications, there is no Cursor propriety. I know is a CoreCursor class in Windows.UI.Core . Am I suppose to use it somehow? 回答1: Window.Current.CoreWindow.PointerCursor = new Windows.UI.Core.CoreCursor(Windows.UI.Core.CoreCursorType.Hand, 1); 回答2: WinRT XAML Toolkit has an attached property

问题 Im trying to open a App-Bar when the user reaches the end of the (ScrollViewer)Page... Therefore I need a indicator when the end is reached... My Scrollviewer (maybe because WP8) has no "ViewChanged"-event like posted in other questions And this solution is just overkill for my Problem I think: http://blogs.msdn.com/b/slmperf/archive/2011/06/30/windows-phone-mango-change-listbox-how-to-detect-compression-end-of-scroll-states.aspx I cant find any event within this Viewer which could help me...

问题 I have a strange problem happening intermittently with my apps where textbox controls would disappear intermittently. I have narrowed the cause of this down to having image files (small logos etc) on my page. I have managed to create a simple project which contains an xaml page with an image and 2 textblocks (these are in grids). I have found on two test tablets that I can re-create the problem by going to task manager and creating a dump file for the running app. After I do this twice and
