问题 I've tried using map.SetView(LocationRect.CreateLocationRect(locations)); But the thing is I need the all the pushpins to be shown as well. Using the above method only takes the location into account. Some pushpins gets cropped especially corner ones. Is there a better way to do this? Thanks. 回答1: LocationRect.CreateLocationRect(locations) gives you the binding box of the locations, so you could artificially inflate that a little (for example, by adding/subtracting a tenth of a degree from

问题 I have a public timer and in its Tick event I send a message to my ViewModel. I start the timer from a button somewhere in my application.

问题 My WP8 app is set to run underneath the lock screen because it needs to continue to run even while the screen is locked, but I want to be able to detect when the user unlocks their screen, how do I do this? What methods, if any, are called when the phone is unlocked? 回答1: The frame's Unobscured event will fire when the user unlocks (it will also fire Obscured when the phone is being locked). However these events will also fire for a MessageBox, a Reminder and the like so you will get other

问题 When the software keyboard is shown, it occludes part of the page UI. That is undesirable. Is there a way to automatically update the UI layout just like Android Activity's onConfigurationChanged? 回答1: It appears that one needs to register handler to update the layout: auto inputpane = InputPane::GetForCurrentView(); inputpane->Showing += ref new TypedEventHandler<InputPane^, InputPaneVisibilityEventArgs^>(this, &MainPage::OnInputPaneVisibilityChanged); inputpane->Hiding += ref new
