问题 I have a Pivot with 2 PivotItems. I'm trying to detect whether the user swiped left or right. I thought I could detect this by checking the difference between the ManipulationStarted and ManipulationCompleted point. But whatever I do, those events won't get triggered. <Pivot x:Name="albumart_pivot" Margin="0,-30,0,0" ManipulationStarted="ManipulationStartedEvent" ManipulationCompleted="ManipulationCompletedEvent" ManipulationMode="TranslateX"> <PivotItem Margin="0"> <Grid> <Rectangle Canvas

问题 I'm using the FilePicker for Windows Universal apps and I'm trying to launch the File Picker from MainPage.xaml and then navigate to a different page (LoadPhoto.xaml) to render the selected image. I initially implemented my app so that I'd navigate to LoadPhoto.xaml and then, as part of loading the page, I'd call the File Picker. However that caused issues when resuming the app, so I moved the File Picker call out of the constructor. In the newest implementation, I call the file picker from

问题 I subscribe to OrientationChanged event in the constructor like this: public SecondPage() { this.InitializeComponent(); deviceOrientationSensor = SimpleOrientationSensor.GetDefault(); if (deviceOrientationSensor != null) { deviceOrientationSensor.OrientationChanged += OrientationChanged; } } and then: private void OrientationChanged(SimpleOrientationSensor sender, SimpleOrientationSensorOrientationChangedEventArgs args) { deviceOrientation = args.Orientation; // the rest... } So the problem

问题 I'm trying to build a simple select method for querying Linq-to-SQL table thru a generic static method. I'm stuck at creating the expression dynamically. Same kind of question here: LINQ : Dynamic select T is the class of the database table (Person) P is the type of the value. The value and property types should be the same (F.ex String) column is the name of property on the given class ("Name") value is the where statement value for the field ("Jack") F.ex Select all persons where name is

问题 I got some problems with getting caret index of TextBox in Windows Store App(WP 8.1). I need to insert specific symbols to the text when button is pressed. I tried this: text.Text = text.Text.Insert(text.SelectionStart, "~"); But this code inserts symbol to the beginning of text, not to the place where caret is. UPDATE I updated my code thanks to Ladi. But now I got another problem: I'm building HMTL editor app so my default TextBlock.Text is: <!DOCTYPE html>\r\n<html>\r\n<head>\r\n</head>\r

问题 (I can find many answers for Windows Phone 7 which probably work Windows Phone 8/8.1 Silverlight, but not for Windows Phone [Store] 8.1) While testing my application, I want to use a dummy server response. Since it's a large amount of data that includes quotation marks, I don't want to use a constant string and have to escape everything.
