问题 I am kind of beginner in UWP Platform and I am building an app using template 10. I have used GridView for a particular page, but the problem is that the GridView shows its borders when you hover over it or select its item.

问题 So I have been experimenting with the IOT serial sample and RP2 since the october release opened up the serial pins. Im using the windows iot serial sample. Have a few issues i cant figure out. The read data seems incomplete. I have an arduino outputting an analog input reading through the serial at 9600 baud.

问题 I have a Windows 10 Universal App that does not include line numbers in the Exception objects .ToString() method. If I have a method like private void ThrowException() { try { throw new Exception("Test"); } catch (Exception e) { Debug.WriteLine(ex.ToString()); } } When I check the output, I don't see the line number where there exception was thrown. I added a Post Build event to the project: xcopy $(ProjectDir)$(OutDir)*.pdb $(ProjectDir)$(OutDir)AppX\*.pdb The pdb file is in the Debug folder

问题 Is there any way to not only be notified of a ScrollViewer 's scroll, but to be able to prevent it. Something like a ScrollChanging event so I can set e.Cancel to true ? (I don't want to disable scrolling, nor do I want to implement it myself because it seems impossible to get the ScrollBar 's events to detect a user dragging them. At least in UWP .) The problem is that ScrollViewer_PointerWheelChanged isn't raised when it scrolls. Only when it doesn't have any need to scroll does it fire. 来源

问题 I'm writing a C# Universal Windows Application that loads a model from a .obj file and I would like to render that model so that the user can rotate it and scale it. Is there a way to render it in the app? Preferably in the same window? Something like the Map control, it's wrapped inside the app but still interactive. 回答1: I found this MSDN article for Windows 8.1 phone that tells us to use PlaneProjection. <StackPanel.Projection> <PlaneProjection RotationX="-35" RotationY="-35" RotationZ="15

问题 Scenario: I have 3 classes (A,B,C) in my Windows Runtime Component project. class A{} public sealed class B : A {} public sealed class C : A {} On compiling the above code, I get the following error : "Inconsistent accessibility: base class 'A' is less accessible than class 'C'." If I make class A public, it gives a compile error : "Exporting unsealed types is not supported. Please mark type 'MyProject.A' as sealed." But now, if I make A as sealed, then B and C cannot inherit from it.
