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 on windows phone 8 project, in this project, I use panorama template. In first panorama I show the news in a longlistselector. First, I was showing 15 news and nothing was a problem for performance. But now I show 50 news and started to make load time longer I think.

I've reached ItemRealized and

问题 I'm using this code, so user can sets custom background image for the application: private void Button_Click(object sender, RoutedEventArgs e) { PhotoChooserTask photoChooserTask = new PhotoChooserTask(); photoChooserTask.Completed += new EventHandler<PhotoResult>(photoChooserTask_Completed); photoChooserTask.Show(); } void photoChooserTask_Completed(object sender, PhotoResult e) { if (e.TaskResult == TaskResult.OK) { System.Windows.Media.Imaging.BitmapImage bmp = new System.Windows.Media

问题 I am trying to animate an image based on the select pivoted items position. I am currently using the ManipulationDelta event to try and see which direction the user is swiping so that I can fade out or fade in an animated image based on the position of the pivot item. My problem is with the ManipulationDelta event, this event is only ever called once on a pivot item, regardless of how much manipulation of the pivot control is occurring. Does anyone know a way to make it so the pivot items
