问题 I'm having an EditText and a Button in my Frame using C#. After writing inside the edit field and clicking on the Button, I want to hide the virtual soft keyboard. 回答1: You cannot. There is more information on the behavior of the Input Hosting Manager and Soft Keyboard and you can register to know when it shows or becomes hidden. But, you cannot programmatically control whether it's up or down. 回答2: Add a dummy button and set focus to it and the keyboard will be hidden. 回答3: Thanks for your

问题 I've got a WebView with some HTML content which I want to convert into RTF. I've looked at the RTF conversion functions out there and they all look a little flaky to be honest. So my idea is to copy content from the WebView into a RichEditBox , and save to RTF from there. I've seen this example numerous times. WebBrowser1.Document.ExecCommand("SelectAll", false, null); WebBrowser1.Document.ExecCommand("Copy", false, null); Unfortunately, WinRT's WebView control doesn't have a Document

Taking the await commands out makes the compiler shows the following warning: Because this call is not awaited, execution of the

问题 I'm wondering what's the best approach to detect if a ScrollViewer reaches the bottom, right etc. I think I can achieve that by using both PointerWheelChanged for mouse and ManipulationDelta for touch. In these event handlers, I can record the HorizontalOffset to find out when will the scroller reach the end. But I think there could be a better way to do it. I've found this article. But the compression visual states seem not working in winrt. The CurrentStateChanging event method is not

问题 In Windows Store Apps, C++(C# is similar though), doing something like IAsyncAction^ Action = CurrentAppSimulator::ReloadSimulatorAsync(proxyFile); create_task( Action ).then([this]() { }.wait(); results in an unhandled exception. Usually it's Microsoft C++ exception: Concurrency::invalid_operation at memory location 0x0531eb58 And I kind of need for that action to finish to get my In App Purchase information before trying to use it. The weird thing here is that anything else besides
