  • System.WIndows.Application static members are thread safe?

    - by Lirik
    The Application static members are supposed to be thread safe: The public static (Shared in Visual Basic) members of this type are thread safe. In addition, the FindResource and TryFindResource methods and the Properties and Resources properties are thread safe.1 How much can we trust that statement in a multithreaded environment when calling static member methods of System.Windows.Application? Update: It's all in reference to this question: http://stackoverflow.com/questions/2463822/threading-errors-with-application-loadcomponent-key-already-exists/2463866#2463866 I never thought I'd see a real bug in the library, but this must be the day for me... that question seems to show a genuine bug. Usually it's "user error," but this doesn't seem to be the case.

  • MS Surface Tag Visualizer steals contact events

    - by Isak Savo
    I'm struggling with the TagVisualizer control on an MS Surface project. In theory the control seems great, allowing you to respond to input from real world physical objects The problem is that the control will cover the entire screen (since I want to capture tags on the entire screen) and as such, no other controls in my app will receive the touch events. (Unless, they are direct ascendants in the visual tree). In my app, I want to have a "layer" type of a approach, where each layer can respond to (contact) input: Window `- Grid `- LayersPanel `- TagVisualizer `- Layer 1 `- Layer 2 `- Layer 3 `- Layer 4 Now it doesn't matter where I put the tag visualizer, it's always going to steal contact events from all or some of the other layers. (due to the nature of RoutedEvents) To me, it seems like the control is completely useless in practice as it will always interfere with your application's other controls. What am I missing here? So my questions are: Any suggestions on how to work around this? Has anyone used TagVisualizers in a similar scenario? If so, how did you solve this? By the way, the layers all work fine, since they will only steal events that are directly on top of their sub elements (the rest of the layer is invisible to hit testing)

  • MVVM: Thin ViewModels and Rich Models

    - by Dan Bryant
    I'm continuing to struggle with the MVVM pattern and, in attempting to create a practical design for a small/medium project, have run into a number of challenges. One of these challenges is figuring out how to get the benefits of decoupling with this pattern without creating a lot of repetitive, hard-to-maintain code. My current strategy has been to create 'rich' Model classes. They are fully aware that they will be consumed by an MVVM pattern and implement INotifyPropertyChanged, allow their collections to be observed and remain cognizant that they may always be under observation. My ViewModel classes tend to be thin, only exposing properties when data actually needs to be transformed, with the bulk of their code being RelayCommand handlers. Views happily bind to either ViewModels or Models directly, depending on whether any data transformation is required. I use AOP (via Postsharp) to ease the pain of INotifyPropertyChanged, making it easy to make all of my Model classes 'rich' in this way. Are there significant disadvantages to using this approach? Can I assume that the ViewModel and View are so tightly coupled that if I need new data transformation for the View, I can simply add it to the ViewModel as needed?

  • Native ComboBox not displaying choices correctly

    - by anothershrubery
    EDIT: It seems that ListPicker is the way to go but I have had further problems with that detailed Microsoft.Phone.Controls.Toolkit ListPicker throws XamlParseException I have the following ComboBox in code: <ComboBox x:Name="Result" Grid.Column="6" HorizontalAlignment="Center" VerticalAlignment="Center" Foreground="Black" Background="White"> <ComboBoxItem Content="Win" /> <ComboBoxItem Content="Place" /> <ComboBoxItem Content="Lose" /> </ComboBox> But it does not display as I would have expected. When you drop down the ComboBox the options don't appear, it's just like empty items. See below: However, when an item is selected, it displays correctly and the correct index/item is returned. See below: I'm sure there is something simple I have missed but can't put my finger on it. EDIT: Ok I am posting the full code for this.

  • The uncatchable exception

    - by chaiguy
    Another custom MarkupExtension binding question... This time, my converter is being called before DataContext is set on the target element. This isn't a big deal because it will get updated when DataContext eventually receives a value. What is causing problems is the NullReferenceException I'm getting because of DataContext being null. Even though I'm attempting to catch the exception in my value converter: try { return ( (MethodInfo)_member ).Invoke( parameter, null ); } catch { return Binding.DoNothing; } For some reason the debugger is still halting at this point. Now I'm thinking it could be because the exception is happening in another assembly from where it is being caught (I'm trying to package this in a reusable class library, and _member above points to a method in the application assembly). If I run my little test app without the debugger it works fine, however my application is a little more robust and has general exception handling which is getting triggered because of this. I'm wondering if there is just some attribute or something (or perhaps some reflection parameter I'm missing?) I can use to make the exception be caught like it's supposed to.

  • something like INotifyCollectionChanged fires on xml file changed

    - by netmajor
    It's possible to implement INotifyCollectionChanged or other interface like IObservable to enable to bind filtered data from xml file on this file changed ? I see examples with properties or collection, but what with files changes ? I have that code to filter and bind xml data to list box: XmlDocument channelsDoc = new XmlDocument(); channelsDoc.Load("RssChannels.xml"); XmlNodeList channelsList = channelsDoc.GetElementsByTagName("channel"); this.RssChannelsListBox.DataContext = channelsList;

  • XmlDataProvider and XPath bindings don't allow default namespace of XML data?

    - by Andy Dent
    I am struggling to work out how to use default namespaces with XmlDataProvider and XPath bindings. There's an ugly answer using local-name <Binding XPath="*[local-name()='Name']" /> but that is not acceptable to the client who wants this XAML to be highly maintainable. The fallback is to force them to use non-default namespaces in the report XML but that is an undesirable solution. The XML report file looks like the following. It will only work if I remove xmlns="http://www.acme.com/xml/schemas/report so there is no default namespace. <?xml version="1.0" encoding="utf-8"?> <?xml-stylesheet type='text/xsl' href='PreviewReportImages.xsl'?> <Report xsl:schemaLocation="http://www.acme.com/xml/schemas/report BlahReport.xsd" xmlns:xsl="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://www.acme.com/xml/schemas/report"> <Service>Muncher</Service> <Analysis> <Date>27 Apr 2010</Date> <Time>0:09</Time> <Authoriser>Service Centre Manager</Authoriser> Which I am presenting in a window with XAML: <Window x:Class="AcmeTest.ReportPreview" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="ReportPreview" Height="300" Width="300" > <Window.Resources> <XmlDataProvider x:Key="Data"/> </Window.Resources> <StackPanel Orientation="Vertical" DataContext="{Binding Source={StaticResource Data}, XPath=Report}"> <TextBlock Text="{Binding XPath=Service}"/> </StackPanel> </Window> with code-behind used to load an XmlDocument into the XmlDataProvider (seems the only way to have loading from a file or object varying at runtime). public partial class ReportPreview : Window { private void InitXmlProvider(XmlDocument doc) { XmlDataProvider xd = (XmlDataProvider)Resources["Data"]; xd.Document = doc; } public ReportPreview(XmlDocument doc) { InitializeComponent(); InitXmlProvider(doc); } public ReportPreview(String reportPath) { InitializeComponent(); var doc = new XmlDocument(); doc.Load(reportPath); InitXmlProvider(doc); } }

  • Binding to XMLDataProvider in Code Behind

The binding to content of btnOne works as aspected "Button1". But btnTwo is set to an empty string. The Output shows no errors. Thanks for any advice.

  • Avoid the collapsing effect on TreeView after updating data

    - by Manolete
    I have a TreeView used to display events. It works great, however every time new events are coming in and populating the tree collapse the tree again to the original position. That is very annoying when the refresh time is less than 1 second and it does not allow the user to interact with the items of the tree. Is there any way to avoid this behaviour? <TreeView Margin="1" BorderThickness="0" Name="eventsTree" ItemsSource="{Binding EventAlertContainers}" Background="#00000000" ScrollViewer.VerticalScrollBarVisibility="Auto" FontSize="14" VirtualizingStackPanel.IsVirtualizing="True"> <TreeView.Resources> <HierarchicalDataTemplate DataType="{x:Type C:EventAlertContainer}" ItemsSource="{Binding EventAlerts}"> <StackPanel Orientation="Horizontal"> <Image Width="20" Height="20" Margin="3,0" Source="Resources\Process_info_32.png" /> <TextBlock FontWeight="Bold" FontSize="16" Text="{Binding Description}" /> </StackPanel> </HierarchicalDataTemplate> <HierarchicalDataTemplate DataType="{x:Type C:EventAlert}" ItemsSource="{Binding Events}"> <StackPanel Orientation="Horizontal"> <Image Width="20" Height="20" Margin="0,0" Source="Resources\clock2_32.jpg" /> <TextBlock FontWeight="DemiBold" FontSize="14" Text="{Binding Name}" /> </StackPanel> </HierarchicalDataTemplate> <HierarchicalDataTemplate DataType="{x:Type C:Event}"> <StackPanel Orientation="Horizontal"> <Image Width="20" Height="20" Margin="0,0" Source="Resources\Task_32.png" /> <StackPanel Orientation="Vertical"> <TextBlock FontSize="12" Text="{Binding Name}" /> </StackPanel> </StackPanel> </HierarchicalDataTemplate> </TreeView.Resources> </TreeView>

  • Shift+Tab not working in TreeView control

    - by Christian
    I cannot get backwards navigation using Shift+Tab to work in a TreeView that contains TextBoxs, forward navigation using Tab works fine and jump from TextBox to TextBox inside the TreeView. Anytime Shift+Tab is used when one of the TextBoxes inside the TreeView, then the focus is move to the previous control outside the TreeView, instead of the previous control inside the TreeView. Also its only Shift+Tab navigation that are not working correctly, Ctrl+Shift+Tab work as expected and in the correct order. Any suggestions to what I'm doing wrong? Example code: <Window x:Class="TestTabTreeView.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="MainWindow" Height="350" Width="525"> <Window.Resources> <Style TargetType="TreeViewItem"> <Setter Property="KeyboardNavigation.TabNavigation" Value="Continue" /> </Style> </Window.Resources> <Grid> <Grid.RowDefinitions> <RowDefinition Height="Auto" /> <RowDefinition Height="*" /> <RowDefinition Height="Auto" /> </Grid.RowDefinitions> <TextBox Text="First Line" Grid.Row="0" /> <TreeView Grid.Row="1" KeyboardNavigation.TabNavigation="Continue" IsTabStop="False"> <TreeViewItem IsExpanded="True"><TreeViewItem.Header><TextBox Text="Popular Words"/></TreeViewItem.Header> <TreeViewItem><TreeViewItem.Header><TextBox Text="Foo"/></TreeViewItem.Header></TreeViewItem> <TreeViewItem><TreeViewItem.Header><TextBox Text="Bar"/></TreeViewItem.Header></TreeViewItem> <TreeViewItem><TreeViewItem.Header><TextBox Text="Hello"/></TreeViewItem.Header></TreeViewItem> </TreeViewItem> <TreeViewItem IsExpanded="True"><TreeViewItem.Header><TextBox Text="Unpopular Words"/></TreeViewItem.Header> <TreeViewItem><TreeViewItem.Header><TextBox Text="Work"/></TreeViewItem.Header></TreeViewItem> <TreeViewItem><TreeViewItem.Header><TextBox Text="Duplication"/></TreeViewItem.Header></TreeViewItem> </TreeViewItem> </TreeView> <TextBox Text="Last Line" Grid.Row="2" /> </Grid>

  • How to fix rotations in a Rubik's Cube?

    - by Eindbaas
    I'm trying to create a Rubik's Cube in Flash & Papervision and i'm really stuck here. I'm up to the point where i can rotate any plane of cubes once, but after that...it's messed up because all local coordinate systems are messy. I dont really know where to go from here, can anybody give any advice on what do do? I'm not looking for 'read about transformation matrices', i know i should (and i am doing that), but i'm not really sure what to look for. My idea is that, after each rotation, i should fix each coordinate system of each cube again, but i have no idea how. Any hints on what i want to achieve (in words), and why, are much appreciated. http://dl.dropbox.com/u/250155/rubik/main.html (you can press the K key once ;) )

  • Why does my IMultiBindingConverter get an array of strings when used to set TextBox.Text?

    - by mcohen75
    Hi- I'm trying to use a MultiBinding with a converter where the child elements also have a converter. The XAML looks like so: <TextBlock> <TextBlock.Text> <MultiBinding Converter="{StaticResource localizedMessageConverter}" ConverterParameter="{x:Static res:Resources.RecordsFound}" > <Binding Converter="{StaticResource localizedMessageParameterConverter}" ConverterParameter="ALIAS" Path="Alias" Mode="OneWay" /> <Binding Converter="{StaticResource localizedMessageParameterConverter}" ConverterParameter="COUNT" Path="Count" Mode="OneWay" /> </MultiBinding> </TextBlock.Text> The problem I'm facing here is, whenever this is used with a TextBlock to specify the Text property, my IMultiValueConverter implementation gets an object collection of strings instead of the class returned by the IValueConverter. It seems that the ToString() method is called on the result of the inner converter and passed to the IMultiValueConverter. If used to specify the Content property of Label, all is well. It seems to me that the framework is assuming that the return type will be string, but why? I can see this for the MultiBinding since it should yield a result that is compatible with TextBlock.Text, but why would this also be the case for the Bindings inside a MultiBinding? If I remove the converter from the inner Binding elements, the native types are returned. In my case string and int.

  • How do I change the CellErrorStyle for an Xceed Datagrid?

    - by Bob
    So in the Xceed documentation there is a code example that does not work for me. It may be because my grid is bound to a DataGridCollectionView. The objects in the collection used by the datagridcollection are what implement IDataErrorInfo. The errors are showing up just fine. The problem is that they are using the default orange background for errors...I need a red border. Below is the XAML instantiation of my grid. I set the DataCell background property to red just so I could be sure I had access to the grid's properties... I do. I just can't find the way to identify the cell's w/ errors so I can style them. Thanks! <XceedDG:DataGridControl Grid.Row="1" Grid.ColumnSpan="5" ItemsSource="{Binding Path = ABGDataGridCollectionView, UpdateSourceTrigger=PropertyChanged}" Background="{x:Static Views:DataGridControlBackgroundBrushes.ElementalBlue}" IsDeleteCommandEnabled="True" FontSize="16" AutoCreateColumns="False" x:Name="EncounterDataGrid" AllowDrop="True"> <XceedDG:DataGridControl.View> <Views:TableView ColumnStretchMode="All" ShowRowSelectorPane="True" ColumnStretchMinWidth="100"> <Views:TableView.FixedHeaders> <DataTemplate> <XceedDG:InsertionRow Height="40"/> </DataTemplate> </Views:TableView.FixedHeaders> </Views:TableView> </XceedDG:DataGridControl.View> <!--Group Header formatting--> <XceedDG:DataGridControl.Resources> <Style TargetType="{x:Type XceedDG:GroupByControl}"> <Setter Property="Visibility" Value="Collapsed"/> </Style> <Style TargetType="{x:Type XceedDG:DataCell}"> <Setter Property="Background" Value="Red"/> </Style> </XceedDG:DataGridControl.Resources> ...
