silverlight-4.0

问题 I'm having a great deal of difficulty trying to achieve something that should be trivial. I'm using an Implicit Button Style defined in a global XAML resource file. I just want to change the background color of the focused button to red with a ColorAnimation. I've tried a number of different combinations in Storyboard.TargetProperty and Storyboard.TargetName and nothing has worked. How can I achieve this? Thanks in advance. <Style TargetType="Button" > <Setter Property="Template"> <Setter

问题 Has anyone been able to communicate using WCF on Windows Phone Series 7 emulator? I've been trying for the past two days and it's just happening for me. I can get a normal Silverlight control to work in both Silverlight 3 and Silverlight 4, but not the phone version. Here are two versions that I've tried: Version 1 - Using Async Pattern BasicHttpBinding basicHttpBinding = new BasicHttpBinding(); EndpointAddress endpointAddress = new EndpointAddress("http://localhost/wcf/Authentication.svc");

问题 The problem is simple but annoying. I have a button and the click event just opens a link by HtmlPage.Window.Navigate(uri, "_blank"); But it keeps being blocked by the browser. I searched a lot. It seems everyone is using this method but no one mentioned the new tab/windows is being blocked. So what should I do? UPDATE Problem solved. It seems that to navigate to outside web pages, HyperlinkButton should be used. This is not blocked by the browser. "To enable user navigation to other Web

问题 This is a basic question. I have the basic SL4/RIA project set up and I want to create a new method in the domain service and return some data from it.

I am unclear how to handle this anonymous type that was create.. what is the easiest way to return this data? public IQueryable<ApplicationLog> GetApplicationLogsGrouped() { var x = from c in ObjectContext.ApplicationLogs let dt = c.LogDate group c by new { y =

问题 Please post the answer for how to declare dataset in silverlight for windows phone7 using c#? 回答1: There is no support for datasets in WP7. You have to build your own datacollections. (For example you could use the ObservableCollection). My suggestion would be to check the code samples on the MSDN page. (The WeatherForecast example uses webservices to retrieve data). Also I would suggest to read some on the MVVM pattern. (MSDN Article) 回答2: Instead of Dataset you should use

问题 I need to open window pop-up from Silverlight Out-of-Browser application. I've added parameter <param name="enablehtmlaccess" value="true" /> in Index.html, but executing this from code behind: HtmlPage.Window.Navigate(new Uri(myUrl), "_blank", myFeatures); still returns error: Silverlight OOB Error: The DOM/scripting bridge is disabled. I've read about this post, does it mean that I can't open pop-up from OOB? Why I need to do this, because actually I've shown the HTML page in OOB

问题 If I have the following XAML: <toolkit:DataForm Height="100" x:Name="form"> <toolkit:DataForm.EditTemplate> <DataTemplate> <StackPanel Name="stack"></StackPanel> </DataTemplate> </toolkit:DataForm.EditTemplate> </toolkit:DataForm> I can get a reference to "form" by this.FindName("form") from the View. How can I get a reference to "stack"? FindName returns null. 回答1: The problem here is that the xaml content of a DataTemplate belongs to a different NameScope than the outer Xaml. Calling

问题 I'm trying to build a sample game in Silverlight 4 using the MVVM design pattern to broaden my knowledge. I'm using Laurent Bugnion's MvvmLight toolkit as well (found here: http://mvvmlight.codeplex.com/ ). All I want to do right now is move a shape around within a Canvas by pressing specific keys. My solution contains a Player.xaml (just a rectangle; this will be moved around) and MainPage.xaml (the Canvas and an instance of the Player control). To my understanding, Silverlight doesn't
