问题 I'm wondering if there any solution that could make the app automatically adjust the controls position when the keyboard is activated. For example, in the image below, I want to make those four button on the screen move dependently with keyboard. When the keyboard is activated, buttons move to the center and move back when the keyboard is gone. There might be some similar questions here but I couldnt see them in the search result, maybe they are using some different words on title so if this

问题 I have asked this Before i know.. but i cant get a straight answer and can't find a good one on google either.

For example, create a class inherit from DataTemplateSelector first like this: public class MessageDataTemplateSelecotr : DataTemplateSelector { public

问题 I recently just published a small collection of WCF services. When I went into my UWP app to add references I only see the option to generate task based operations. I am a fan of async operations, I also remember this being a feature previously so what is the deal? Screenshot of the section: 回答1: Probably need to clear up a little terminology here. The "asynchronous operations" option that is grayed out refers to the Asychronous Programming Pattern (i.e. BeginXXX, EndXXX methods) where as
