问题 XNA apps (WP7 or WP7.5 apps) that run on a WP8 720p device will get automatically letterboxed so the 480x800 BackBuffer size stays the same (for compatibility I presume). This would be fine, except there appears to be a bug in the XNA compatibility layer. The TouchPanel reports touch locations that are off by the size of the top letterbox blank area. This has two problems: The user's touches will appear to be off making gameplay and menu navigation difficult. Because it is off in the negative

问题 A known "issue" with nesting ListBoxes in a Windows Phone 7 App is that for each parent category their respective child ListBox retains its own SelectedItems list. Well, I have a situation where this is expected behavior, but I'm having issues capturing both the Parent and Child ListBox selected lists. Current Functionality: 1. List item 2. List item 3. Loading of Parent and Child ListBox data is working 4. Multi-select of Parent ListBox items works prefectly 5. Multi-select of Child ListBox

问题 the situation is that I have a list with some HubTile(s) in it, is there any way I can filter the ListBox depending on what is written in a TextBox? For the text box I have the code... private void textBoxSearch_KeyDown(object sender, KeyEventArgs e) { if (e.Key == Key.Enter) { } } Thanks, all help appreciated! 回答1: Sure, just store the list of HubTiles in a data structure, and when the user enters a search query, do a LINQ query on that list, and reset the list. private List<HubTiles>

The reason it doesn't work on an

问题 I tried to compile http://msdn.microsoft.com/en-us/gg266450 But it says It cannot find System.ServiceModel.Syndication I have 2, 3.5, 4 .NET framework installed. In add reference I can see System.ServiceModel and System.ServiceModel.Web version 2 not anything like 3 or 4 so I wonder how I could add that namespace as mentioned here http://msdn.microsoft.com/en-us/library/system.servicemodel.syndication.syndicationfeed(v=vs.95).aspx This is rather incredible that MS has messed with namespaces

问题 I have just finished tombstoning a page in my application when I noticed that I only tombstone the page I am currently viewing, meaning that after I return the pages in the backstack lose all their members and doesn't get tombstoned.. I only find examples on how to tomstone the current page but nothing about tombstoning the backstack pages... What is the elegant way to do this? Just to show How I'm tombstoning: protected override void OnNavigatedTo(NavigationEventArgs e) { if (e

问题 I've done some reading and found that one can only close a windows phone app by throwing an un-handled exception that will close the app. So my question is, how does one do that for the physical back button on the phone? And how does one have the back button close the app only if it's on a certain page ? So the back button would work as normal, but when it eventually falls on a page called 'noBack.xaml' the back button should close the app. EDIT Actually on second thought, even just disabling
