问题 How can I make an event when pressed on Start button (windows Phone) ? UPDATED If it is not possible, so how can I understand that user have pressed START button ? 回答1: The Start and Search buttons themselves are reserved and do not generate events to third party applications. Having said that, two events will be generated when the user pushes the start button: A navigation event with NavigationMode being Forward and IsNavigationInitiator being false A PhoneApplicationService.Deactivated

问题 I have created a class like below: class myclass { Public int myint; } Now I want to restrict the range of myint(min 5 and max 10). I want if any one set the value of myint which is not in the range it will give a compile time error(not runtime error) please help me how to achive it. 回答1: It's experimental, but you could look into Spec#. It can provide you with more compile-time checks. Code Contracts are another option (but that's only available in certain editions of Visual Studio). Edit:

问题 Let's put aside for the moment, the question of whether synchronous-like operations should even be attempted within the context of a Silverlight app. If I use ManualResetEvent as in the following code: static string result; static AutoResetEvent are = new AutoResetEvent(false); static ManualResetEvent mre = new ManualResetEvent(false); public static string AsyncCall() { string url = "https://stackoverflow.com/feeds/tag/silverlight"; WebClient w = new WebClient(); w.DownloadStringCompleted +=

问题 I set IsTabStop to false on a text box and I know that this makes the control unable to receive focus, but according to the Silverlight Forums, it should still be able to receive mouse events. I have the MouseLeftButtonUp event wired and a breakpoint in my tbxTotal_MouseLeftButtonUp method, and it never gets hit during debugging. The thread in the SL Forums is pretty old now, so maybe this was changed in an update somewhere. I want a text box that can't be tabbed to, but is still editable.

问题 I've got a DataGrid that I'm populating with data, and I'd like to copy the value of the cell clicked on into a string. Better yet, I'd like to copy the value out of a specific cell in the row, so if there's a way to load the entire row into an array that'd be better . For instance I'd have a few rows like this: Included | Keyword | Occurrences | Density ------------------------------------------------ Yes | KW1 | 3 | 1.02% Yes | Keyword2 | 1 | 0.25% Yes | KW1 | 3 | 1.021% If I were to click

问题 recently I started working with Prism in Silverlight. I want to use the EventAggregator to Subscribe and Publish events between two ViewModels. As I saw on some guides, the ViewModel's ctor should accept IEventAggregator as a parameter. I can't find out how to do this hence my View always wants to initialize the ViewModel with a parameterless ctor. My ViewModel ctor: MyViewModel(IEventAggregator eventAggregator) { // get the event.... } My View: <UserControl ....> <UserControl.Resources>

问题 Can anyone point me to some patterns for handling async workflows in C#? I know this is coming soon in C# 5 but I was wondering if anyone had already done an implementation in C# 4 that approximates the same effects? Basically I'm writing a lot of async code in Silverlight 4 like this: CallService( (service) => service.DoSomething(1, 2, 3), (response) => { // some local code // need to call another service async CallService( (service) => service.DoSomethingElse(4, 5, 6), (response) => { //
