silverlight-4.0

I'm writing a windows phone 7 app. I have "fatal exception" handling code where I know for sure that the app is totally busted and there's no point in continuing. (I'm hoping I never get here...). Since there's nothing more my app can do other than quit I want the user to be able to close the app. But I noticed there is no System.Environment.Exit() in the Silverlight 4 SDK for Windows Phone 7. Is there another way to quit the app programmatically? App Cert Reqt: 5.1.2 Application Termination The application must handle exceptions raised by the .NET Framework and not terminate unexpectedly.

After researching a solution to this for three days, finally I gave up. Now I need your help to solve this. Scenario: I've a GridView in a Usercontrol (Lets say WLMSLogs.xaml) and My GridView ItemSource is binded to a List from the ViewModel (WMLSLogsViewModel.cs) Lets say the List has 4 items (EventID, Name, Request and Response). BothRequest and Responses are XML Strings. GridView needs to display some of the List items in RowDetailsTemplate under different tab items. So I'm displaying Request and Response under respective TabItems. <GridView x:Name="WMLSLogGrid" ItemsSource="{Binding

Given the list of new features announced in Silverlight 4, when is WPF still required? WPF still has a lot fuller 3D rendering capabilities. Also even though they announced enhancements to the commanding and binding capabilities, that's no guarantee that it will have the full ability that WPF currently has or will have in the next version Edit: After playing around with Silverlight 4 beta, it looks like pretty much all of the new features (webcam, file access, full screen keyboard, COM interop, etc) only work when the application is elevated trust, and elevated trust can only be enable when

Is it possible to bind to a ConverterParameter in Silverlight 4.0? For instance I would like to do something like this and bind the ConverterParameter to an object in a ViewModel for instance. If this is not possible are there any other options? <RadioButton Content="{Binding Path=Mode}" IsChecked="{Binding Converter={StaticResource ParameterModeToBoolConverter}, ConverterParameter={Binding Path=DataContext.SelectedMode,ElementName=root}}" /> Unfortunetly no, you can't bind to a ConverterParameter. There's two options I've used in the past: instead of using a Converter, create a property on

I am new in Silverlight. When I add some control to my xaml file with Visual Studio it set controls name with Name property, but there is also x:Name. Is there any difference and when to use each of them? Thanks. In Brief Yes there is a difference. The bottom line is that x:Name can be used on object elements that do not have Name properties of their own. A longer explanation You can only use Name on an element that represents an object that actually does have a Name property. For example anything that derives from FrameworkElement . The x:Name attribute may be placed on any element that

This is my scenario. I have 2 Properties. Type and State. Type is an Enum with 3 values eg, ball, car, arrow. State is an int which would accept 3 state values eg., -1, 0, 1. Also, I have 9 images for each state values. Like, if I select type as ball and value as -1, I want to display a Red color ball. If I select type as arrow and value as 1, I want to display a up arrow. etc., I'm able to do this in WPF. I created 3 DataTemplates with an empty Image. Then, I use DataTrigger to check and update the particular image for the selected StateValue. But, in silverlight how can I do this. I know, I
