As you use ‘GZipMessageEncodingBindingElement’, I assume you are using the MS GZIP sample. Have a look at DecompressBuffer() in GZipMessageEncoderFactory.cs and you will understand what’s going on in buffered mode. For the sake of example, let’s say you have a message of uncompressed size 50M, compressed size 25M. DecompressBuffer will receive an ‘ArraySegment buffer’ param … Read more
Actually you can. The trick is to make an Attached property and add a property changed callback that actually calls GoToState: public class StateHelper { public static readonly DependencyProperty StateProperty = DependencyProperty.RegisterAttached( “State”, typeof( String ), typeof( StateHelper ), new UIPropertyMetadata( null, StateChanged ) ); internal static void StateChanged( DependencyObject target, DependencyPropertyChangedEventArgs args ) { … Read more
If you write an XNA Game, you will have access to an explicit Exit() method. If you are writing traditional Silverlight project, then NO, there is no way to programatically close your app. See also Peter Torr’s Blog entry on Exiting Silverlight Apps in Windows Phone 7. There he also mentions the option of throwing … Read more
ColinE is right with all his informations. I only want to add my subclass of ObservableCollection that I use for this specific case. public class SmartCollection<T> : ObservableCollection<T> { public SmartCollection() : base() { } public SmartCollection(IEnumerable<T> collection) : base(collection) { } public SmartCollection(List<T> list) : base(list) { } public void AddRange(IEnumerable<T> range) { foreach … Read more
I found the answer here: http://forums.silverlight.net/forums/p/149264/377212.aspx MVC recognizes the MetaDataType attribute, but other projects do not. Before validating, you need to manually register the metadata class: TypeDescriptor.AddProviderTransparent( new AssociatedMetadataTypeTypeDescriptionProvider(typeof(Customer), typeof(CustomerMetadata)), typeof(Customer)); var isValid = Validator.TryValidateObject(new Customer(), context, results, true);
You can’t Bind to Header because it’s not a FrameworkElement. You can make the text dynamic by modifying the Header Template like this: xmlns:data=”clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Data” xmlns:dataprimitives=”clr-namespace:System.Windows.Controls.Primitives;assembly=System.Windows.Controls.Data” <data:DataGridTemplateColumn> <data:DataGridTemplateColumn.HeaderStyle> <Style TargetType=”dataprimitives:DataGridColumnHeader”> <Setter Property=”Template”> <Setter.Value> <ControlTemplate> <TextBlock Text=”{Binding MeetingName, Source={StaticResource LocStrings}}” /> </ControlTemplate> </Setter.Value> </Setter> </Style> </data:DataGridTemplateColumn.HeaderStyle> </data:DataGridTemplateColumn>
The WebClient only supports a single operations, it cannot download multiple files. You haven’t shown your code, but my guess is that you are somehow firing a new request before the old is completed. My bet is that WebClient.IsBusy is true when you attempt to perform another fetch. See the following thread: wb.DownloadFileAsync throw “WebClient … Read more
Although you cannot programatically create it, you can load it from a XAML string in code like this: public static DataTemplate Create(Type type) { return (DataTemplate) XamlReader.Load( @”<DataTemplate xmlns=””http://schemas.microsoft.com/client/2007″”> <” + type.Name + @”/> </DataTemplate>” ); } The snippet above creates a data template containing a single control, which may be a user control with … Read more
The query string works perfectly, but I wouldn’t use DateTime.Now, because it forces the user to re-download the app every time. Instead, we use the following: protected void Page_Load(object sender, EventArgs e) { var versionNumber = Assembly.GetExecutingAssembly().GetName().Version.ToString(); this.myApp.Source += “?” + versionNumber; } This way all you have to do is increment the version number … Read more
In the past I ‘ve written an application that supports “live” editing of data objects from multiple locations: many instances of the app can edit the same object at the same time, and when someone pushes changes to the server everyone else gets notified and (in the simplest scenario) sees those changes immediately. Here’s a … Read more
