  • javascript binding

    - by Michael
    MyObj = { ajax: null, init: function() { this.ajax = Cc["@mozilla.org/xmlextras/xmlhttprequest;1"].createInstance(); this.ajax.onload = function() { return function() {this.onload.apply(this, [null]);} }; }, onload: function () { Reader.log("I really hope I can use `this.ajax` here"); } } isn't it correct way to bind onload to MyObj? For some reason onload never called. However if I avoid binding and just put this.ajax.onload = this.onload then onload invoked. How to get binding work?

  • Binding to 'To' In Storyboard

    - by Peanut
    I'll try to make this as simple as I can. I want to do this: <Storyboard x:Name="MoveToLocation"> <DoubleAnimation Duration="0:0:0.5" To="{Binding X}" Storyboard.TargetProperty="(UIElement.RenderTransform).(CompositeTransform.TranslateX)" Storyboard.TargetName="grid" d:IsOptimized="True"/> </Storyboard> As you may have noticed the Binding on 'To' Property does not work. It seems to only accept static values. How does one do this animation with MVVM? I cant just put in static data, cause it's going to change. Thanks.

  • Re-binding an ajaxForm after content re-loads with ajax (jQuery 1.4.2)

    - by Cristian
    I'm trying to figure out why this is a problem when using jQuery 1.4.2 and not 1.3.2. This is my function: function prepare_logo_upload() { $("#logo-upload-form").ajaxForm({ //alert(responseText); success: function(responseText) { //alert(responseText); $('#profile .wrapper').html(responseText); prepare_logo_upload(); } }); } Every other live event works but can't use the .live() method because ajaxForm is a plugin. I have noticed this also for other types of binding (clicks) using the old form (re-binding after callback) Can you tell me if it is a way of solving this? This is a similar question, but due to my newbie reputation here, can't comment or ask a question there, so I'll ask a new one here. - http://stackoverflow.com/questions/2208880/jquery-bind-ajaxform-to-a-form-on-a-page-loaded-via-load Thank you!

  • WPF Binding : Object in a object

    - by Philippe
    I have a form in WPF with 2 textbox : <TextBox Name="txtName" Text="{Binding Contact.Name}"/> <TextBox Name="txtAddressNumber" Text="{Binding Contact.Address.Number}"/> and I have 2 class : public class ContactEntity { public string Name {get;set;} public AddressEntity Address {get;set;} } public class AddressEntity { public int Number {get;set} } The Name property binds fine. But the Number property of the Address object inside the Contact object does not binds. What I'm doing wrong ?

  • Binding in ContentControl Crash

    - by ImJames
    Can anyone tell me why this crashes my app? There seems to be some endless recursion by I can't figure out why. I get this exception Logical tree depth exceeded while traversing the tree.

  • MVC4 not binding a list of basic types

    - by admanb
    I cannot, for the life of me, get this data to bind. Here's my JavaScript: var params = { 'InvItemIDs': ["188475", "188490"]}; $.post("api/Orders/OrderFromInventory?" + $.param(params)) and the Controller action: public HttpResponseMessage OrderFromInventory(IList<int> InvItemIDs) { return new HttpResponseMessage(); } I've built the query string so that it's sending: ?InvItemIDs=188475&InvItemIDs=188490 as well as ?InvItemIDs[]=188475&InvItemIDs[]=188490 and even ?InvItemIDs[0]=188475&InvItemIDs[1]=188490 and none of them are binding. InvItemIDs is always null. What am I doing wrong? EDIT: So it turns out all this is a bug (or something) in the new Web API controller code in MVC4. As soon as I moved the exact same code over to a standard controller it started working. I'm still interested if anyone has any insight as to why the Web API would break this binding.

  • Silverlight 4 Binding to ConverterParameter

    - by FrEEzE2046
    Hello everybody, I have a ValueConverter which needs to be called with a dynamic parameter, depending on a property. I can't see a way to do this ... Width="{Binding ActualWidthValue, Source={StaticResource VisibleSize}, Converter={StaticResource Fraction}}" The "Fraction" converter get's (or should get) a parameter of type System.Size, which contains a numerator and denumerator. This value (should) depend on a ItemCollection.Count. Resetting the ItemCollection should reinvoke the Converter with the new values. My first idea was to manually change the ConverterParameter in CodeBehind on the PropertyChanged event of my ItemCollection DependencyProperty. But, as I know now, Silverlight has no GetBinding() method. I heard about GetBindingExpression and tried to do. But MyGrid.GetBindingExpression(Grid.ActualHeightProperty) is always returning null, although the Binding is already established. So, what can I do to reach my target?

  • Which programming language should i choose? (much more info inside) [closed]

    - by Andreas
    I am not completely sure if this is the right place to put this question, but since it's the programming thread I guessed that there's many experienced programmers here. :) Ok, hello! My name is Andreas and I am a 16 years old guy from Norway. For some time now I've wanted to learn a programming language. Six months ago I started learning C++, but quit withing a week due to lack of motivation. The same thing happend only 2 months ago when I tried to learn Lua. I wanted to program mods to the game Garry's mod, and was really motivated. Then I stopped playing the game, and the programming stopped with it. Today though I am ready again. The only difference is that I am not completely sure what I want to do with the language. I only want to create something, and I miss the progress of failing and enduring hard work until I finally solve the problem I've worked on for hours. What I am trying to say is; Is there any program out there that allows me, a complete noob (I didn't learn that much in a week, so I like to call myself a beginner), to create apps, mods or something similar but at the same time being qualified as a first time language? I was thinking of Java, because Android, Minecraft and many other applications and games use it. But I've heard that it is going to be replaced by a program called HTML 5 (whatever that is), is this true? I certainly don't want to spend many hours of my life on something that is useless in a year or two. Hopefully I didn't make this too complicated. I know that it is hard to recommend something when I don't have a goal, but I really don't know what to say. Have a good day kind folks! - Andreas EDIT:* I did not know that this was an off topic question, really sorry!

  • Login window language has changed after update on Snow Leopard

    - by Leonardo
    After the latest update (beginning of Dec. 2012) on Snow Leopard my login window language has changed. My system is set to be in english but the login windows now is in french. Currently I am in France so I suspect that during the update something has revealed my location and installed something in the locale of the current location. It doesn't seem fair to me, I want to switch it back to english but I couldn't find a way to do it.

  • Changing labels language in LibreOffice

    - by clabacchio
    I'm using the Italian version of LibreOffice 4.0.4, and writing a document in English. I set English as document language, and the spellchecking works properly. However, when I insert captions and cross references, the labels are in italian. For example Tabella instead of Table. What should I change in order to have the proper labeling, besides installing an English version of LibreOffice Writer??

There is more code involved for checking token validation, but in my opinion at least MEX should get published and CreateBehavior() should get invoked in order for me to proceed further.

  • Dependency Property Set Priority: CodeBehind vs. XAML

    - by LukePet
    When I initialize a control property from code, the binding to the same property defined on XAML don't work. Why? For Example, I set control properties on startup with this statements: myControl.SetValue(UIElement.VisibilityProperty, DefaultProp.Visibility); myControl.SetValue(UIElement.IsEnabledProperty, DefaultProp.IsEnabled); and on xaml I bind the property of myControl in this way: IsEnabled="{Binding Path=IsKeyControlEnabled}" now, when the property "IsKeyControlEnabled" changes to false, myControl remains enabled (because it's initialize with true value). How can I do?

  • MVVM: Binding radio buttons to a view model?

    - by David Veeneman
    I have been trying to bind a group of radio buttons to a view model using the IsChecked button. After reviewing other posts, it appears that the IsChecked property simply doesn't work. I have put together a short demo that reproduces the problem, which I have included below. Here is my question: Is there a straightforward and reliable way to bind radio buttons using MVVM? Thanks. Additional information: The IsChecked property doesn't work for two reasons: When a button is selected, the IsChecked properties of other buttons in the group don't get set to false. When a button is selected, its own IsChecked property does not get set after the first time the button is selected. I am guessing that the binding is getting trashed by WPF on the first click. Demo project: Here is the code and markup for a simple demo that reproduces the problem. Create a WPF project and replace the markup in Window1.xaml with the following: <Window x:Class="WpfApplication1.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Window1" Height="300" Width="300" Loaded="Window_Loaded"> <StackPanel> <RadioButton Content="Button A" IsChecked="{Binding Path=ButtonAIsChecked, Mode=TwoWay}" /> <RadioButton Content="Button B" IsChecked="{Binding Path=ButtonBIsChecked, Mode=TwoWay}" /> </StackPanel> </Window> Replace the code in Window1.xaml.cs with the following code (a hack), which sets the view model: using System.Windows; namespace WpfApplication1 { /// <summary> /// Interaction logic for Window1.xaml /// </summary> public partial class Window1 : Window { public Window1() { InitializeComponent(); } private void Window_Loaded(object sender, RoutedEventArgs e) { this.DataContext = new Window1ViewModel(); } } } Now add the following code to the project as Window1ViewModel.cs: using System.Windows; namespace WpfApplication1 { public class Window1ViewModel { private bool p_ButtonAIsChecked; /// <summary> /// Summary /// </summary> public bool ButtonAIsChecked { get { return p_ButtonAIsChecked; } set { p_ButtonAIsChecked = value; MessageBox.Show(string.Format("Button A is checked: {0}", value)); } } private bool p_ButtonBIsChecked; /// <summary> /// Summary /// </summary> public bool ButtonBIsChecked { get { return p_ButtonBIsChecked; } set { p_ButtonBIsChecked = value; MessageBox.Show(string.Format("Button B is checked: {0}", value)); } } } } To reproduce the problem, run the app and click Button A. A message box will appear, saying that Button A's IsChecked property has been set to true. Now select Button B. Another message box will appear, saying that Button B's IsChecked property has been set to true, but there is no message box indicating that Button A's IsChecked property has been set to false--the property hasn't been changed. Now click Button A again. The button will be selected in the window, but no message box will appear--the IsChecked property has not been changed. Finally, click on Button B again--same result. The IsChecked property is not updated at all for either button after the button is first clicked.

  • Silverlight: Binding a custom control to an arbitrary object

    - by Ryan Bates
    I am planning on writing a hierarchical organizational control, similar to an org chart. Several org chart implementations are out there, but not quite fit what I have in mind. Binding fields in a DataTemplate to a custom object does not seem to work. I started with a generic, custom control, i.e. public class NodeBodyBlock : ContentControl { public NodeBodyBlock() { this.DefaultStyleKey = typeof(NodeBodyBlock); } } It has a simple style in generic.xaml: <Style TargetType="org:NodeBodyBlock"> <Setter Property="Width" Value="200" /> <Setter Property="Height" Value="100" /> <Setter Property="Background" Value="Lavender" /> <Setter Property="FontSize" Value="11" /> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="org:NodeBodyBlock"> <Border Width="{TemplateBinding Width}" Height="{TemplateBinding Height}" Background="{TemplateBinding Background}" CornerRadius="4" BorderBrush="Black" BorderThickness="1" > <Grid> <VisualStateManager/> ... clipped for brevity </VisualStateManager.VisualStateGroups> <ContentPresenter Content="{TemplateBinding Content}" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" /> </Grid> </Border> </ControlTemplate> </Setter.Value> </Setter> </Style> My plan now is to be able to use this common definition as a base definition of sorts, with customized version of it used to display different types of content. A simple example would be to use this on a user control with the following style: <Style TargetType="org:NodeBodyBlock" x:Key="TOCNode2"> <Setter Property="ContentTemplate"> <Setter.Value> <DataTemplate> <StackPanel> <TextBlock Text="{Binding Path=NodeTitle}"/> </StackPanel> </DataTemplate> </Setter.Value> </Setter> </Style> and an instance defined as <org:NodeBodyBlock Style="{StaticResource TOCNode2}" x:Name="stTest" DataContext="{StaticResource DummyData}" /> The DummyData is defined as <toc:Node NodeNumber="mynum" NodeStatus="A" NodeTitle="INLine Node Title!" x:Key="DummyData"/> With a simple C# class behind it, where each of the fields is a public property. When running the app, the Dummy Data values simply do not show up in the GUI. A trivial test such as <TextBlock Text="{Binding NodeTitle}" DataContext="{StaticResource DummyData}"/> works just fine. Any ideas around where I am missing the plot?

  • WPF: Binding to ListBoxItem.IsSelected doesn't work for off-screen items

    - by Qwertie
    In my program I have a set of view-model objects to represent items in a ListBox (multi-select is allowed). The viewmodel has an IsSelected property that I would like to bind to the ListBox so that selection state is managed in the viewmodel rather than in the listbox itself. However, apparently the ListBox doesn't maintain bindings for most of the off-screen items, so in general the IsSelected property is not synchronized correctly. Here is some code that demonstrates the problem. First XAML: <StackPanel> <StackPanel Orientation="Horizontal"> <TextBlock>Number of selected items: </TextBlock> <TextBlock Text="{Binding NumItemsSelected}"/> </StackPanel> <ListBox ItemsSource="{Binding Items}" Height="200" SelectionMode="Extended"> <ListBox.ItemContainerStyle> <Style TargetType="{x:Type ListBoxItem}"> <Setter Property="IsSelected" Value="{Binding IsSelected}"/> </Style> </ListBox.ItemContainerStyle> </ListBox> <Button Name="TestSelectAll" Click="TestSelectAll_Click">Select all</Button> </StackPanel> C# Select All handler: private void TestSelectAll_Click(object sender, RoutedEventArgs e) { foreach (var item in _dataContext.Items) item.IsSelected = true; } C# viewmodel: public class TestItem : NPCHelper { TestDataContext _c; string _text; public TestItem(TestDataContext c, string text) { _c = c; _text = text; } public override string ToString() { return _text; } bool _isSelected; public bool IsSelected { get { return _isSelected; } set { _isSelected = value; FirePropertyChanged("IsSelected"); _c.FirePropertyChanged("NumItemsSelected"); } } } public class TestDataContext : NPCHelper { public TestDataContext() { for (int i = 0; i < 200; i++) _items.Add(new TestItem(this, i.ToString())); } ObservableCollection<TestItem> _items = new ObservableCollection<TestItem>(); public ObservableCollection<TestItem> Items { get { return _items; } } public int NumItemsSelected { get { return _items.Where(it => it.IsSelected).Count(); } } } public class NPCHelper : INotifyPropertyChanged { public event PropertyChangedEventHandler PropertyChanged; public void FirePropertyChanged(string prop) { if (PropertyChanged != null) PropertyChanged(this, new PropertyChangedEventArgs(prop)); } } Two separate problems can be observed. If you click the first item and then press Shift+End, all 200 items should be selected; however, the heading reports that only 21 items are selected. If you click "Select all" then all items are indeed selected. If you then click an item in the ListBox you would expect the other 199 items to be deselected, but this does not happen. Instead, only the items that are on the screen (and a few others) are deselected. All 199 items will not be deselected unless you first scroll through the list from beginning to end (and even then, oddly enough, it doesn't work if you perform scrolling with the little scroll box). My questions are: Can someone explain precisely why this occurs? Can I avoid or work around the problem?

  • Binding Image.Source to String in WPF ?

    - by Mohammad
    I have below XAML code : <Window x:Class="WpfApplication1.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" DataContext="{Binding RelativeSource={RelativeSource Self}}" WindowStartupLocation="CenterScreen" Title="Window1" Height="300" Width="300"> <Grid> <Image x:Name="TestImage" Source="{Binding Path=ImageSource}" /> </Grid> </Window> Also, there is a method that makes an Image from a Base64 string : Image Base64StringToImage(string base64ImageString) { try { byte[] b; b = Convert.FromBase64String(base64ImageString); MemoryStream ms = new System.IO.MemoryStream(b); System.Drawing.Image img = System.Drawing.Image.FromStream(ms); ////////////////////////////////////////////// //convert System.Drawing.Image to WPF image System.Drawing.Bitmap bmp = new System.Drawing.Bitmap(img); IntPtr hBitmap = bmp.GetHbitmap(); System.Windows.Media.ImageSource imageSource = System.Windows.Interop.Imaging.CreateBitmapSourceFromHBitmap(hBitmap, IntPtr.Zero, Int32Rect.Empty, BitmapSizeOptions.FromEmptyOptions()); Image wpfImage = new Image(); wpfImage.Source = imageSource; wpfImage.Width = wpfImage.Height = 16; ////////////////////////////////////////////// return wpfImage; } catch { Image img1 = new Image(); img1.Source = new BitmapImage(new Uri(@"/passwordManager;component/images/TreeView/empty-bookmark.png", UriKind.Relative)); img1.Width = img1.Height = 16; return img1; } } Now, I'm gonna bind TestImage to the output of Base64StringToImage method.

  • Binding update adds news series to WPF Toolkit chart (instead of replacing/updating series)

    - by Mal Ross
    I'm currently recoding a bar chart in my app to make use of the Chart class in the WPF Toolkit. Using MVVM, I'm binding the ItemsSource of a ColumnSeries in my chart to a property on my viewmodel. Here's the relevant XAML: <charting:Chart> <charting:ColumnSeries ItemsSource="{Binding ScoreDistribution.ClassScores}" IndependentValuePath="ClassName" DependentValuePath="Score"/> </charting:Chart> And the property on the viewmodel: // NB: viewmodel derived from Josh Smith's BindableObject public class ExamResultsViewModel : BindableObject { // ... private ScoreDistributionByClass _scoreDistribution; public ScoreDistributionByClass ScoreDistribution { get { return _scoreDistribution; } set { if (_scoreDistribution == value) { return; } _scoreDistribution = value; RaisePropertyChanged(() => ScoreDistribution); } } However, when I update the ScoreDistribution property (by setting it to a new ScoreDistribution object), the chart gets an additional series (based on the new ScoreDistribution) as well as keeping the original series (based on the previous ScoreDistribution). To illustrate this, here are a couple of screenshots showing the chart before an update (with a single data point in ScoreDistribution.ClassScores) and after it (now with 3 data points in ScoreDistribution.ClassScores): Now, I realise there are other ways I could be doing this (e.g. changing the contents of the original ScoreDistribution object rather than replacing it entirely), but I don't understand why it's going wrong in its current form. Can anyone help?
