  • wpf datagrid current item binding

    - by tk
    I want to bind a content of Label to the selected item of a datagrid. I thought the 'current item' binding expression would work, but it is not. My xaml code and code-behind c# is like below. <Window x:Class="WpfApplication2.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="MainWindow" Height="512" Width="847"> <DockPanel LastChildFill="True"> <Label Content="{Binding Data/colA}" DockPanel.Dock="Top" Height="30"/> <DataGrid ItemsSource="{Binding Data}"></DataGrid> </DockPanel> </Window> namespace WpfApplication2 { public partial class MainWindow : Window { public MainWindow() { InitializeComponent(); this.DataContext = new MyData(); } } public class MyData { DataTable data; public MyData() { data = new DataTable(); data.Columns.Add("colA"); data.Columns.Add("colB"); data.Rows.Add("aa", 1); data.Rows.Add("bb", 2); } public DataTable Data { get { return data; } } } } The label shows the first item of the DataTable, and does not change when i select other items on the datagrid. It seems the current item of dataview does not change. What should i do to bind it to the current selected item of datagrid?

  • WPF UserControl weird binding problem

    - by Heko
    Hello! Im usign a Ribbon Window and in the "content area beneath" I have a grid in which I will be displaying UserControls. To demonstrate my problem lets take a look at this simple UserControl: <ListView x:Name="lvPersonList"> <ListView.View> <GridView> <GridViewColumn Width="120" Header="Name" DisplayMemberBinding="{Binding Name}"/> <GridViewColumn Width="120" Header="Height" DisplayMemberBinding="{Binding Height}"/> </GridView> </ListView.View> </ListView> And the code: public partial class MyUserControl: UserControl { private List<Person> personList; public TestSnpList() { InitializeComponent(); this.personList = new List<Person>(); this.personList.Add(new Person { Name = "Chuck Norris", Height = 210 }); this.personList.Add(new Person { Name = "John Rambo", Height = 200 }); this.lvPersonList.ItemsSource = personList; } } public class Person { public string Name { get; set; } public int Height { get; set; } } The parent Window: <Grid x:Name="grdContent" DockPanel.Dock="Top"> <controls:MyUserControl x:Name="myUserControl" Visibility="Visible"/> </Grid> I don't understant why this binding doesn't work. Instead of values (Name and Height) I get full class names. If I use this code in a Window it works fine. Any ideas? I would like this user contorl works for itself (it gets the data form the DB and represents it in a ListView)... Thanks!

  • Binding Data to a TextBlock using Domain Data Source

    - by TFisher
    I have a map with hotspots for each state (done in Expression Blend). I capture each MouseEnter of the state (1 thru 50). I pass that into my Domain Data Source: Dim activebox As Path = TryCast(sender, Path) activebox.Fill = mouseOverColor Dim StateID As Integer = CInt(Right(activebox.Name, 2)) Dim _StateContext As New StateContext myDataGrid.ItemsSource = _StateContext.States _StateContext.Load(_StateContext.GetStateByStateIDQuery(StateID.Text)) The above works fine for a datagrid, listbox and even a dataform. But I created a popup with a stackpanel that has textblocks. popupStatesBox.DataContext = ?????????????? popupStatesBox.IsOpen = True 'popup does open but has no data -- popupStatesBox.xaml <Popup x:Name="popupStatsBox" Margin="8,35,0,8" DataContext="{Binding}" IsOpen="false" Width="268" HorizontalAlignment="Left"> <StackPanel x:Name="Layout" Background="Black"> <TextBlock x:Name="tbState" Text="{Binding StateName /> <TextBlock x:Name="tbAbbrev" Text="{Binding Abbreviation}" /> </StackPanel> </Popup> How do I get the textblocks to display the values from the _StateContext. StackPanel has DataContext but no ItemsSource. What am I missing?

  • Valueurl Binding On Large Arrays Causes Sluggish User Interface

    - by Hooligancat
    I have a large data set (some 3500 objects) that returns from a remote server via HTTP. Currently the data is being presented in an NSCollectionView. One aspect of the data is a path pack to the server for a small image that represents the data (think thumbnail for simplicity). Bindings works fantastically for the data that is already returned, and binding the image via a valueurl binding is easy to do. However, the user interface is very sluggish when scrolling through the data set - which makes me think that the NSCollectionView is retrieving all the image data instead of just the image data used to display the currently viewable images. I was under the impression that Cocoa controls were smart enough to only retrieve data for the information that is actually being output to the user interface through lazy loading. This certainly seems to be the case with NSTableView - but I could be misguided on this thought. Should valueurl binding act lazily and, moreover, should it act lazily in an NSCollectionView? I could create a caching mechanism (in fact I already have such a thing in place for another application - see my post here if you are interested http://stackoverflow.com/questions/1740209/populating-nsimage-with-data-from-an-asynchronous-nsurlconnection) but I really don't want to go this route if I don't have to for this specific implementation as the user could potentially change data sets often and may only want small sub-sets of the data. Any suggested approaches? Thanks!

  • MyContainer derived from FrameworkElement with binding support.

    - by alex2k8
    To understand how the binding works, I implemented MyContainer derived from FrameworkElement. This container allowes to set Children and adds them into the logical tree. But the binding by ElementName does not work. What can I do with MyContainer to make it work, leaving the parent as FrameworkElement? C#: public class MyContainer : FrameworkElement { public MyContainer() { Children = new List<FrameworkElement>(); } public List<FrameworkElement> Children { get; set; } protected override IEnumerator LogicalChildren { get { return Children.GetEnumerator(); } } } XAML: <Window x:Class="WpfLogicalTree.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:WpfLogicalTree" Title="Window1" Height="300" Width="300"> <StackPanel> <local:MyContainer> <local:MyContainer.Children> <TextBlock Text="Foo" x:Name="_source" /> <TextBlock Text="{Binding Path=Text, ElementName=_source}" x:Name="_target"/> </local:MyContainer.Children> </local:MyContainer> <Button Click="Button_Click">Test</Button> </StackPanel> </Window> Window1.cs private void Button_Click(object sender, RoutedEventArgs e) { MessageBox.Show(_target.Text); }

  • Problems with binding to Window Height and Width

    - by D.H.
    I have some problems when I try to bind the height and width of a window to properties in my view model. Here is a small sample app to illustrate the problem. This is the code in app.xaml.xs public partial class App : Application { protected override void OnStartup(StartupEventArgs e) { base.OnStartup(e); MainWindow mainWindow = new MainWindow(); MainWindowViewModel mainWindowViewModel = new MainWindowViewModel(); mainWindow.DataContext = mainWindowViewModel; mainWindow.Show(); } } This is MainWindow.xaml: <Window x:Class="TestApp.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Height="{Binding WindowHeight}" Width="{Binding WindowWidth}" BorderThickness="{Binding WindowBorderThickness}"> </Window> And this is the view model: public class MainWindowViewModel { public int WindowWidth { get { return 100; } } public int WindowHeight { get { return 200; } } public int WindowBorderThickness { get { return 8; } } } When the program is started the getters of WindowHeight and WindowBorderThickness (but not WindowWidth) are called, so the height and the border of the window is set properly, but not the width. I then add button that will trigger PropertyChanged for all properties, so that the view model now looks like this: public class MainWindowViewModel : INotifyPropertyChanged { public event PropertyChangedEventHandler PropertyChanged; public void TriggerPropertyChanges() { if (PropertyChanged != null) { PropertyChanged(this, new PropertyChangedEventArgs("WindowWidth")); PropertyChanged(this, new PropertyChangedEventArgs("WindowHeight")); PropertyChanged(this, new PropertyChangedEventArgs("WindowBorderThickness")); } } public ICommand ButtonCommand { get { return new RelayCommand(delegate { TriggerPropertyChanges(); }); } } public int WindowWidth { get { return 100; } } public int WindowHeight { get { return 200; } } public int WindowBorderThickness { get { return 8; } } } Now, when I click the button, the getter of WindowBorderThickness is called, but not the ones for WindowWidth and WindowHeight. It all just seems very weird and inconsistent to me. What am I missing?

  • Binding a TextBox's Width to its parent container's ActualWidth

    - by Praetorian
    Hi, I'm loading a Textbox and a Button into a horizontal StackPanel programmatically. The size of the button (which only contains an Image) is fixed, but I can't get the textbox to fill the available width of its parent. This is what the code looks like: StackPanel parent = new StackPanel() { Orientation = Orientation.Horizontal, HorizontalAlignment = HorizontalAlignment.Stretch, VerticalAlignment = VerticalAlignment.Top, }; TextBox textbox = new TextBox() { HorizontalAlignment = HorizontalAlignment.Stretch, VerticalAlignment = VerticalAlignment.Top, //MinWidth = 375, }; Button btn = new Button() { Content = new Image() { MaxHeight = 40, MaxWidth = 40, MinHeight = 40, MinWidth = 40, Margin = new Thickness( 0 ), Source = new BitmapImage( new Uri( "btnimage.png", UriKind.Relative ) ), }, HorizontalAlignment = HorizontalAlignment.Right, BorderBrush = new SolidColorBrush( Colors.Transparent ), Margin = new Thickness( 0 ), }; btn.Click += ( ( s, e ) => OnBtnClicked( s, e, textbox ) ); parent.Children.Add( textbox ); parent.Children.Add( btn ); If I uncomment the MinWidth setting for the textbox it is displayed as I want it to, but I'd like to not have to specify a width explicitly. I tried adding a binding as follows but that doesn't work at all (the textbox just disappears!) Binding widthBinding = new Binding() { Source = parent.ActualWidth, }; passwdBox.SetBinding( TextBox.WidthProperty, widthBinding ); Thanks for your help in advance!

  • Performance problems loading XML with SSIS, an alternative way!

    - by AtulThakor
    I recently needed to load several thousand XML files into a SQL database, I created an SSIS package which was created as followed: Using a foreach container to loop through a directory and load each file path into a variable, the “Import XML” dataflow would then load each XML file into a SQL table.       Running this, it took approximately 1 second to load each file which seemed a massive amount of time to parse the XML and load the data, speaking to my colleague Martin Croft, he suggested the use of T-SQL Bulk Insert and OpenRowset, so we adjusted the package as followed:     The same foreach container was used but instead the following SQL command was executed (this is an expression):     "INSERT INTO MyTable(FileDate) SELECT   CAST(bulkcolumn AS XML)     FROM OPENROWSET(         BULK         '" + @[User::CurrentFile]  + "',         SINGLE_BLOB ) AS x"     Using this method we managed to load approximately 20 records per second, much faster…for data loading! For what we wanted to achieve this was perfect but I’ll leave you with the following points when making your own decision on which solution you decide to choose!      Openrowset Method Much faster to get the data into SQL You’ll need to parse or create a view over the XML data to allow the data to be more usable(another post on this!) Not able to apply validation/transformation against the data when loading it The SQL Server service account will need permission to the file No schema validation when loading files SSIS Slower (in our case) Schema validation Allows you to apply transformations/joins to the data Permissions should be less of a problem Data can be loaded into the final form through the package When using a schema validation errors can fail the package (I’ll do another post on this)

  • XML: Multiple roots + text content outside the root. Does anyone do it?

    - by Jeffrey Sweeney
    I have another one of those "is it done in XML" questions (my last one about xml comments hasn't been answered if anyone has a good explanation) I was just wondering if anyone, anywhere would: Use multiple root elements in an XML document Put text content outside of a root element W3C discourages these practices, Javascript's DOMParser doesn't even allow these cases, and I can't think of one sane reason to do either of these things. However, I know how bizarre some implementations of XML have been, so I wouldn't be surprised. Does anyone have any real world examples where this would be done? I will also accept an answer that specifies if other mainstream parsers allow doing either of these.

  • Is it convenient to use a XML/JSON generated based system? [closed]

    - by Marcelo de Assis
    One of my clients insists that we missed a requisite for the project(a little social network, using PHP + MySql), is that all queries are made from XML / JSON static files (using AJAX) and not directly from the database. Edit: The main reason, stated by client, is a way to economize bandwith. Even the file loading, has to be using AJAX, to avoid server side processing. We will still use a database to store and insert data. These XML / JSON files will be (re) generated whenever any data is changed by CMS or users. As the project was developed without this "technique", we'll have a lot of work ahead, so I would like to avoid that. I'm asking if it's convenient to use a XML generated based system, because I think a database is already "optimized" and secure to deal with a lot of data traffic. Other issue I'm afraid of, is a chance of conflict when a user is trying to read a XML/JSON which is being just generated.

  • Unit test: How best to provide an XML input?

    - by TheSilverBullet
    I need to write a unit test which validates the serialization of two attributes of an XML(size ~ 30 KB) file. What is the best way to provide an input for this test? Here are the options I have considered: Add the file to the project and use a file reader Pass the contents of the XML as a string Create the XML through a program and pass it Which is my best option and why? If there is another way which you think is better, I would love to hear it.

  • How can I pass an external instance to the constructor of an object that's being created using the default XNA XML content loader?

    - by Michael
    I'm trying to understand how to use the XNA XML content importer to instantiate non-trivial objects that are more than a collection of basic properties (e.g., a class that inherits from DrawableGameObject or GameObject and requires other things to be passed into its constructor). Is it possible to pass existing external instances (e.g., an instance of the current Game) to the constructor of an object that's being created using the default XNA XML content loader? For example, imagine that I have the following class, inheriting from DrawableGameComponent: public class Character : DrawableGameComponent { public string Name { get; set; } public Character(Game game) : base(game) { } public override void Update(GameTime gameTime) { } public override void Draw(GameTime gameTime) { } } If I had a simple class that did not need other parameters in its constructor (i.e., the Game instance), then I could simply use this XML: <XnaContent> <Asset Type="MyNamespace.Character"> <Name>John Doe</Name> </Asset> </XnaContent> ...and then create an instance of Character using this code: var character = Content.Load<Character>("MyXmlAssetName"); But that won't work because I need to pass the need to pass the Game into the constructor. What's the best way to handle this situation? Is there a way to pass in things like the current Game using the default XNA XML content loader? Do I need to write my own XML loader? (If so, how?) Is there a better object-oriented design that I should be using for my classes? Note: Although I used Game in this example, I'm really just asking how to pass any type of existing instance to my constructors. (For example, I'm using the Farseer Physics Engine, and some of my classes also need a reference to the Farseer World object too.) Thanks in advance.

  • Why do XML namespace URIs use the http scheme?

    - by svick
    A XML namespace should be a URI, but it can use any URI scheme, including those that are not URLs. Then why do all widely used XML namespaces use the http scheme (e.g. http://www.w3.org/XML/1998/namespace), considering that trying to use the URI as an URL by retrieving that document using the HTTP protocol is not guaranteed to do anything useful (and often doesn't)? I understand the usefulness of DNS domains in namespace names to help guarantee uniqueness. But that doesn't require the http scheme, there could be a separate scheme for that (something like namespace:w3.org/XML/1998/namespace). This would avoid the confusion between URIs and URLs, while maintaining domain-based uniqueness.

  • How do I use Content.Load() with raw XML files?

    - by xnanewb
    I'm using the Content.Load() mechanism to load core game definitions from XML files. It works fine, though some definitions should be editable/moddable by the players. Since the content pipeline compiles everything into xnb files, that doesn't work for now. I've seen that the inbuild XNA Song content processor does create 2 files. 1 xnb file which contains meta data for the song and 1 wma file which contains the actual data. I've tried to rebuild that mechanism (so that the second file is the actual xml file), but for some reason I can't use the namespace which contains the IntermediateSerializer class to load the xml (obviously the namespace is only available in a content project?). How can I deploy raw, editable xml files and load them with Content.Load()?

  • .NET and XML: How can I read nested namespaces (<abc:xyz:name attr="value"/>)?

    - by Entrase
    Suppose there is an element in XML data: <abc:xyz:name attr="value"/> I'm trying to read it with XmlReader. The problem is that I get XmlException that says The ‘:’ character, hexadecimal value 0x3A, cannot be included in a name I have already declared "abc" namespace. I have also tried adding "abc:xyz" and "xyz" namespaces. But this doesn't help at all. I could replace some text before parsing but there may be some more elegant solution. So what should I do? Here is my code: XmlReaderSettings settings = new XmlReaderSettings() NameTable nt = new NameTable(); XmlNamespaceManager nsmgr = new XmlNamespaceManager(nt); nsmgr.AddNamespace("abc", ""); nsmgr.AddNamespace("xyz", ""); XmlParserContext context = new XmlParserContext(null, nsmgr, null, XmlSpace.None); // So this reader can't read <abc:xyz:name attr="value"/> XmlReader reader = XmlReader.Create(path, settings, context);“
