silverlight-4.0

I've seen a few other Silverlight 'vs' questions around, but couldn't find any for this particular match-up. I'm trying to define the way in which my objects bound to a ListBox will display. I've defined a DataTemplate , but I'm really not sure where this should end and the ItemContainerStyle should begin. Question 1: Is the ItemContainerStyle just a wrapper for the DataTemplate so that a common item style can be applied to different data layouts? Question 1a: If so, in the event that a common item style isn't required, is the ItemContainerStyle even necessary or can all the layout and styling

I am trying to change the Control template on a ListBoxItem when It is selected from the ListBox. To do so, I was going to get the selected ListBoxItem from the ListBox itself, and set the control template on that. How would i go about doing this? I have tried, SelectedItem and that returns the bound object within the ListBoxItem. You can retrieve the item container from the bound item by using the ItemContainerGenerator : object selectedItem = listBox.SelectedItem; ListBoxItem selectedListBoxItem = listBox.ItemContainerGenerator.ContainerFromItem(selectedItem) as ListBoxItem; Now you can do

I need to send live updates from server to client. I know that WCF generally can do this. However silverlight is a picky client.. Does anyone know how to configure WCF to send the real-time updates to Silverlight client? Snipets from configs and walkthrough will be greatly appreciated. Use WCF Callbacks. A good walkthrough that shows several configurations for this is available on the MSDN . We used the NetTCPBinding at my last job to great effect. It's very fast and efficient. The downside is that it doesn't support secure transport on Silverlight, so if that's a requirement you'll need to go

I am trying to prototype a Rpc Call to a JBOSS webserver from Silverlight (4). I have written the code and it is working in a console application - so I know that Jboss is responding to the web request. Porting it to silverlight 4, is causing issues: let uri = new Uri(queryUrl) // this is the line that hangs let request : HttpWebRequest = downcast WebRequest.Create(uri) request.Method <- httpMethod; request.ContentType <- contentType It may be a sandbox issue, as my silverlight is being served off of my file system and the Uri is a reference to the localhost - though I am not even getting an

Silverlight can use WCF, Web Services, REST based services, .NET RIA Services, but it seems like Silverlight and .NET RIA Services are preferred most. I want to know if there are any common issues [which can be a show stopper if one goes ahead with this combo] that you have seen in practical implementation of SL with .NET RIA Services. Thanks, Rahul Working with metadata (and writing it by yourself) is really pain in the ass. Especially when you need to update your model. RIA tutorial applications look quite well on a small database but working with a model consisting of dozens of entites, you

This works fine, and correctly inserts non-breaking spaces into the string: <TextBlock Text="Non Breaking Text Here"></TextBlock> But what I really need is to replace spaces with non-breaking spaces during data binding. So I wrote a simple value converter that replaces spaces with "   ". It does indeed replace spaces with "   " but "   " is displayed literally instead of showing as a non-breaking space. This is my converter: public class SpaceToNbspConverter : IValueConverter { #region IValueConverter Members public object Convert(object value, Type targetType, object parameter, CultureInfo
