• Contextual bindings with Ninject 2.0

  - by Przemaas

  In Ninject 1.0 I had following binding definitions: Bind<ITarget>().To<Target1>().Only(When.Context.Variable("variable").EqualTo(true)); Bind<ITarget>().To<Target2>(); Given such bindings I had calls: ITarget target = kernel.Get<ITarget>(With.Parameters.ContextVariable("variable", true)); ITarget target = kernel.Get<ITarget>(With.Parameters.ContextVariable("variable", false)); First call was resolved to instance of Target1, second call was resolved to instance of Target2. How to translate this into Ninject 2.0?

• WPF Binding Error reported when Binding appears to work fine

  - by Noldorin

  I am trying to create a custom TabItem template/style in my WPF 4.0 application (using VS 2010 Pro RTM), but inspite of everything seeming to work correctly, I am noticing a binding error in the trace window. The resource dictionary XAML I use to style the TabItems of a TabControl is given in full here. (Just create a simple TabControl with several items and apply the given ResourceDictionary to test it out.) Specifically, the error is occurring due to the following line (discovered through trial and error testing, since Visual Studio isn't actually reporting it at design tim <TranslateTransform X="{Binding ActualWidth, ElementName=leftSideBorderPath}"/> The full error given in the trace (Ouput window) is the following: System.Windows.Data Error: 2 : Cannot find governing FrameworkElement or FrameworkContentElement for target element. BindingExpression:Path=ActualWidth; DataItem=null; target element is 'TranslateTransform' (HashCode=35345840); target property is 'X' (type 'Double') The error occurs on load and is repeated 5 times then (note that I have 3 tab items in my example). It also occurs consistently and repeatedly whenever for the Window is resized, for example - filling the Output window. Perhaps every time the TabItem layout is updated? And again, though it is not reported, the error very much seems to be due to the fact that I am binding to any element at all, not specifically leftSideBorderPath or the the ActualWidth propertry. For example, changing this line to the following fixes things. <TranslateTransform X="25"/> Unfortunately, hard-coding the value isn't really an option. This issue seems very strange to me in that the binding does appear to be giving the correct results. (Inspecting the X value of the TranslateTransform at runtime clearly shows the correct bound value, and the ClipGeometry when viewed is exactly what it hsould be.) Neither Visual Studio nor WPF seems to be giving me any more information on the cause of the error perhaps (setting PresentationTraceSources.TraceLevel to High doesn't help), yet the fact that things are working despite the error being reported inclines me to think that this is some fringe-case WPF bug. As a side note, the Visual Studio WPF designer and XAML editor are giving me a problem with the following line: <PathGeometry Figures="{Binding Source={StaticResource TabSideFillFigures}}"/> Although WPF (at runtime) is perfectly happy binding Figures to the TabSideFillFigures string, with the Binding enforcing the use of the TypeConverter, the XAML editor and WPF designer are complaining. All the XAML code for the ControlTemplate is underlined and I get the following errors in the Error List: Error 9 '{DependencyProperty.UnsetValue}' is not a valid value for the 'System.Windows.Controls.Control.Template' property on a Setter. C:\Users\Alex\Documents\Visual Studio 2010\Projects\Ircsil\devel\Ircsil\MainWindow.xaml 1 1 Ircsil Error 10 Object reference not set to an instance of an object. C:\Users\Alex\Documents\Visual Studio 2010\Projects\Ircsil\devel\Ircsil\Skins\Default\MainSkin.xaml 58 17 Ircsil Again, to repeat, everything works perfectly well at runtime, which is what makes this particularly odd... Could someone perhaps shed some light on these issues, in particular the first (which seems to be a potential WPF bug), and the latter (which seems to be a Visual Studio bug). Any sort of feedback or suggestions would be much appreciated!

• Change binding value, not binding itself

  - by Sam

  I've got a WPF UserControl containing a DependencyProperty (MyProperty). The DependencyProperty is bound to a Property in the DataContext. Now in the UserControl I want to change the value of the bound property. But if I assign MyProperty = NewValue the Binding is lost and replaced by NewValue. What I want to achieve is change the DataContext-property the DependencyProperty is bound to. How do I achieve this instead of changing the binding? To clarify: using something like MyTextBox.Text = "0"; I'll release the binding. How would I set Text, leave the binding intact so the property Text is bound to will change, too.

• Differences between Dynamic Dispatch and Dynamic Binding

  - by Prog

  I've been looking on Google for a clear diffrentiation with examples but couldn't find any. I'm trying to understand the differences between Dynamic Dispatch and Dynamic Binding in Object Oriented languages. As far as I understand, Dynamic Dispatch is what happens when the concrete method invoked is decided at runtime, based on the concrete type. For example: public void doStuff(SuperType object){ object.act(); } SuperType has several subclasses. The concrete class of the object will only be known at runtime, and so the concrete act() implementation invoked will be decided at runtime. However, I'm not sure what Dynamic Binding means, and how it differs from Dynamic Dispatch. Please explain Dynamic Binding and how it's different from Dynamic Dispatch. Java examples would be welcome.

• wpf binding by selected value - swap out bound object without disturbing binding

  - by Andy Clarke

  Hi, I've got combo box bound to a custom collection type - its basically an overridden ObservableCollection which I've added a facility to update the underlying collection (via Unity). I don't want to confuse the issue too much, but thats the background. My xaml looks like this <ComboBox ItemsSource="{Binding Manufacturers}" DisplayMemberPath="Name" SelectedValuePath="ID" SelectedValue="{Binding Vehicle.ManufacturerID}" /> And in my overridden collection i was doing this. index = IndexOf(oldItem); Insert(index, (T)newItem); RemoveAt(index + 1); I had hoped because it was bound by value, that inserting the new object(which had the same id) and then removing the old one would work. But it seems that although its bound by SelectedValue it still knows that its being swapped for a different one. The combo just looses its selection. Can anyone help please?

• How are Implicit-Heap dynamic Storage Binding and Dynamic type binding similar?

  - by Appy

  "Concepts of Programming languages" by Robert Sebesta says - Implicit Heap-Dynamic Storage Binding: Implicit Heap-Dynamic variables are bound to heap storage only when they are assigned values. It is similar to dynamic type binding. Can anyone explain the similarity with suitable examples. I understand the meaning of both the phrases, but I am an amateur when it comes to in-depth details.

• Java Dynamic Binding

  - by Chris Okyen

  I am having trouble understanding the OOP Polymorphic principl of Dynamic Binding ( Late Binding ) in Java. I looked for question pertaining to java, and wasn't sure if a overall answer to how dynamic binding works would pertain to Java Dynamic Binding, I wrote this question. Given: class Person { private String name; Person(intitialName) { name = initialName; } // irrelevant methods is here. // Overides Objects method public void writeOutput() { println(name); } } class Student extends Person { private int studentNumber; Student(String intitialName, int initialStudentNumber) { super(intitialName); studentNumber = initialStudentNumber; } // irrellevant methods here... // overides Person, Student and Objects method public void writeOutput() { super.writeOutput(); println(studentNumber); } } class Undergaraduate extends Student { private int level; Undergraduate(String intitialName, int initialStudentNumber,int initialLevel) { super(intitialName,initialStudentNumber); level = initialLevel; } // irrelevant methods is here. // overides Person, Student and Objects method public void writeOutput() { super.writeOutput(); println(level); } } I am wondering. if I had an array called person declared to contain objects of type Person: Person[] people = new Person[2]; person[0] = new Undergraduate("Cotty, Manny",4910,1); person[1] = new Student("DeBanque, Robin", 8812); Given that person[] is declared to be of type Person, you would expect, for example, in the third line where person[0] is initialized to a new Undergraduate object,to only gain the instance variable from Person and Persons Methods since doesn't the assignment to a new Undergraduate to it's ancestor denote the Undergraduate object to access Person - it's Ancestors, methods and isntance variables... Thus ...with the following code I would expect person[0].writeOutput(); // calls Undergraduate::writeOutput() person[1].writeOutput(); // calls Student::writeOutput() person[0] to not have Undergraduate's writeOutput() overidden method, nor have person[1] to have Student's overidden method - writeOutput(). If I had Person mikeJones = new Student("Who?,MikeJones",44,4); mikeJones.writeOutput(); The Person::writeOutput() method would be called. Why is this not so? Does it have to do with something I don't understand about relating to arrays? Does the declaration Person[] people = new Person[2] not bind the method like the previous code would?

• Why binding is not a native feature in most of the languages?

  - by Gulshan

  IMHO binding a variable to another variable or an expression is a very common scenario in mathematics. In fact, in the beginning, many students think the assignment operator(=) is some kind of binding. But in most of the languages, binding is not supported as a native feature. In some languages like C#, binding is supported in some cases with some conditions fulfilled. But IMHO implementing this as a native feature was as simple as changing the following code- int a,b,sum; sum := a + b; a = 10; b = 20; a++; to this- int a,b,sum; a = 10; sum = a + b; b = 20; sum = a + b; a++; sum = a + b; Meaning placing the binding instruction as assignments after every instruction changing values of any of the variable contained in the expression at right side. After this, trimming redundant instructions (or optimization in assembly after compilation) will do. So, why it is not supported natively in most of the languages. Specially in the C-family of languages? Update: From different opinions, I think I should define this proposed "binding" more precisely- This is one way binding. Only sum is bound to a+b, not the vice versa. The scope of the binding is local. Once the binding is established, it cannot be changed. Meaning, once sum is bound to a+b, sum will always be a+b. Hope the idea is clearer now. Update 2: I just wanted this P# feature. Hope it will be there in future.

• JavaScript Data Binding Frameworks

  - by dwahlin

  Data binding is where it’s at now days when it comes to building client-centric Web applications. Developers experienced with desktop frameworks like WPF or web frameworks like ASP.NET, Silverlight, or others are used to being able to take model objects containing data and bind them to UI controls quickly and easily. When moving to client-side Web development the data binding story hasn’t been great since neither HTML nor JavaScript natively support data binding. This means that you have to write code to place data in a control and write code to extract it. Although it’s certainly feasible to do it from scratch (many of us have done it this way for years), it’s definitely tedious and not exactly the best solution when it comes to maintenance and re-use. Over the last few years several different script libraries have been released to simply the process of binding data to HTML controls. In fact, the subject of data binding is becoming so popular that it seems like a new script library is being released nearly every week. Many of the libraries provide MVC/MVVM pattern support in client-side JavaScript apps and some even integrate directly with server frameworks like Node.js. Here’s a quick list of a few of the available libraries that support data binding (if you like any others please add a comment and I’ll try to keep the list updated): AngularJS MVC framework for data binding (although closely follows the MVVM pattern). Backbone.js MVC framework with support for models, key/value binding, custom events, and more. Derby Provides a real-time environment that runs in the browser an in Node.js. The library supports data binding and templates. Ember Provides support for templates that automatically update as data changes. JsViews Data binding framework that provides “interactive data-driven views built on top of JsRender templates”. jQXB Expression Binder Lightweight jQuery plugin that supports bi-directional data binding support. KnockoutJS MVVM framework with robust support for data binding. For an excellent look at using KnockoutJS check out John Papa’s course on Pluralsight. Meteor End to end framework that uses Node.js on the server and provides support for data binding on  the client. Simpli5 JavaScript framework that provides support for two-way data binding. WinRT with HTML5/JavaScript If you’re building Windows 8 applications using HTML5 and JavaScript there’s built-in support for data binding in the WinJS library.   I won’t have time to write about each of these frameworks, but in the next post I’m going to talk about my (current) favorite when it comes to client-side JavaScript data binding libraries which is AngularJS. AngularJS provides an extremely clean way – in my opinion - to extend HTML syntax to support data binding while keeping model objects (the objects that hold the data) free from custom framework method calls or other weirdness. While I’m writing up the next post, feel free to visit the AngularJS developer guide if you’d like additional details about the API and want to get started using it.

• Binding property to Silverlight dependency property independent of DataContext

  - by Simon_Weaver

  I'm trying to make an Address control that has an IsReadOnly property, which will make every TextBox inside read only when set to true. <my:AddressControl Grid.Column="1" Margin="5" IsReadOnly="True"/> I've managed to do this just fine with a dependency property and it works. Here's a simple class with the dependency property declared : public partial class AddressControl : UserControl { public AddressControl() { InitializeComponent(); this.DataContext = this; } public static readonly DependencyProperty IsReadOnlyProperty = DependencyProperty.Register("IsReadOnly", typeof(bool), typeof(AddressControl), null); public bool IsReadOnly { get { return (bool)GetValue(IsReadOnlyProperty); } set { SetValue(IsReadOnlyProperty, value); } } } In the XAML for this codebehind file I have a Textbox for each address line: <TextBox IsReadOnly="{Binding IsReadOnly}" Text="{Binding City, Mode=TwoWay}"/> <TextBox IsReadOnly="{Binding IsReadOnly}" Text="{Binding State, Mode=TwoWay}"/> <TextBox IsReadOnly="{Binding IsReadOnly}" Text="{Binding Zip, Mode=TwoWay}"/> Like i said this works just fine. The problem is that the Address control itself is bound to its parent object (I have several addresses I am binding). <my:AddressControl DataContext="{Binding ShippingAddress, Mode=TwoWay}" IsReadOnly="True"> <my:AddressControl DataContext="{Binding BillingAddress, Mode=TwoWay}" IsReadOnly="True"> The problem is that as soon as I set DataContext to something other than 'this' then the binding for IsReadOnly breaks. Not surprising because its looking for IsReadOnly on the Address data entity and it doesn't exist or belong there. I've tried just about every combination of binding attributes to get IsReadOnly to bind to the AddressControl obejct but can't get it working. I've tried things like this, but I can't get IsReadOnly to bind independently to the AddressControl property instead of its DataContext. <TextBox IsReadOnly="{Binding RelativeSource={RelativeSource Self}, Path=IsReadOnlyProperty}" Text="{Binding City, Mode=TwoWay}" /> I think I'm pretty close. What am I doing wrong?

• 7 Reasons for Abandonment in eCommerce and the need for Contextual Support by JP Saunders

  - by Tuula Fai

  Shopper confidence, or more accurately the lack thereof, is the bane of the online retailer. There are a number of questions that influence whether a shopper completes a transaction, and all of those attributes revolve around knowledge. What products are available? What products are on offer? What would be the cost of the transaction? What are my options for delivery? In general, most online businesses do a good job of answering basic questions around the products as the shopper engages in the online journey, navigating the product catalog and working through the checkout process. The needs that are harder to address for the shopper are those that are less concerned with product specifics and more concerned with deciding whether the transaction met their needs and delivered value. A recent study by the Baymard Institute [1] finds that more than 60% of ecommerce site visitors will abandon their shopping cart. The study also identifies seven reasons for abandonment out of the commerce process [2]. Most of those reasons come down to poor usability within the commerce experience. Distractions. External distractions within the shopper’s external environment (TV, Children, Pets, etc.) or distractions on the eCommerce page can drive shopper abandonment. Ideally, the selection and check-out process should be straightforward. One common distraction is to drive the shopper away from the task at hand through pop-ups or re-directs. The shopper engaging with support information in the checkout process should not be directed away from the page to consume support. Though confidence may improve, the distraction also means abandonment may increase. Poor Usability. When the experience gets more complicated, buyer’s remorse can set in. While knowledge drives confidence, a lack of understanding erodes it. Therefore it is important that the commerce process is streamlined. In some cases, the number of clicks to complete a purchase is lengthy and unavoidable. In these situations, it is vital to ensure that the complexity of your experience can be explained with contextual support to avoid abandonment. If you can illustrate the solution to a complex action while the user is engaged in that action and address customer frustrations with your checkout process before they arise, you can decrease abandonment. Fraud. The perception of potential fraud can be enough to deter a buyer. Does your site look credible? Can shoppers trust your brand? Providing answers on the security of your experience and the levels of protection applied to profile information may play as big a role in ensuring the sale, as does the support you provide on the product offerings and purchasing process. Does it fit? If it is a clothing item or oversized furniture item, another common form of abandonment is for the shopper to question whether the item can be worn by the intended user. Providing information on the sizing applied to clothing, physical dimensions, and limitations on delivery/returns of oversized items will also assist the sale. A photo alone of the item will help, as it answers some of those questions, but won’t assuage all customer concerns about sizing and fit. Sometimes the customer doesn’t want to buy. Prospective buyers might be browsing through your catalog to kill time, or just might not have the money to purchase the item! You are unlikely to provide any information in contextual support to increase the likelihood to buy if the shopper already has no intentions of doing so. The customer will still likely abandon. Ensuring that any questions are proactively answered as they browse through your site can only increase their likelihood to return and buy at a future date. Can’t Buy. Errors or complexity at checkout can be another major cause of abandonment. Good contextual support is unlikely to help with severe errors caused by technical issues on your site, but it will have a big impact on customers struggling with complexity in the checkout process and needing a question answered prior to completing the sale. Embedded support within the checkout process to patiently explain how to complete a task will help increase conversion rates. Additional Costs. Tax, shipping and other costs or duties can dramatically increase the cost of the purchase and when unexpected, can increase abandonment, particularly if they can’t be adequately explained. Again, a lack of knowledge erodes confidence in the purchase, and cost concerns in particular, erode the perception of your brand’s trustworthiness. Again, providing information on what costs are additive and why they are being levied can decrease the likelihood that the customer will abandon out of the experience. Knowledge drives confidence and confidence drives conversion. If you’d like to understand best practices in providing contextual customer support in eCommerce to provide your shoppers with confidence, download the Oracle Cloud Service and Oracle Commerce - Contextual Support in Commerce White Paper. This white paper discusses the process of adding customer support, including a suggested process for finding where knowledge has the most influence on your shoppers and practical step-by-step illustrations on how contextual self-service can be added to your online commerce experience.

• Windows Phone app: Binding data in a UserControl which is contained in a ListBox

  - by Alexandros Dafkos

  I have an "AddressListBox" ListBox that contains "AddressDetails" UserControl items, as shown in the .xaml file extract below. The Addresses collection is defined as ObservableCollection< Address Addresses and Street, Number, PostCode, City are properties of the Address class. The binding fails, when I use the "{Binding property}" syntax shown below. The binding succeeds, when I use the "dummy" strings in the commented-out code. I have also tried "{Binding Path=property}" syntax without success. Can you suggest what syntax I should use for binding the data in the user controls? <ListBox x:Name="AddressListBox" DataContext="{StaticResource dataSettings}" ItemsSource="{Binding Path=Addresses, Mode=TwoWay}"> <ListBox.ItemTemplate> <DataTemplate> <!-- <usercontrols:AddressDetails AddressRoad="dummy" AddressNumber="dummy2" AddressPostCode="dummy3" AddressCity="dummy4"> </usercontrols:AddressDetails> --> <usercontrols:AddressDetails AddressRoad="{Binding Street}" AddressNumber="{Binding Number}" AddressPostCode="{Binding PostCode}" AddressCity="{Binding City}"> </usercontrols:AddressDetails> </DataTemplate> </ListBox.ItemTemplate> </ListBox>

• How to configure multiple WCF binding configurations for the same scheme

  - by Sandor Drieënhuizen

  I have a set of IIS7-hosted net.tcp WCF services that serve my ASP.NET MVC web application. The web application is accessed over the internet. WCF Services (IIS7) <--> ASP.NET MVC Application <--> Client Browser The services are username authenticated, the account that a client (of my web application) uses to logon ends up as the current principal on the host. I want one of the services to be authenticated differently, because it serves the view model for my logon view. When it's called, the client is obviously not logged on yet. I figure Windows authentication serves best or perhaps just certificate based security (which in fact I should use for the authenticated services as well) if the services are hosted on a machine that is not in the same domain as the web application. That's not the point here though. Using multiple TCP bindings is what's giving me trouble. I tried setting it up like this in my client configuration: <bindings> <netTcpBinding> <binding> <security mode="TransportWithMessageCredential"> <message clientCredentialType="UserName"/> </security> </binding> <binding name="public"> <security mode="Transport"> <message clientCredentialType="Windows"/> </security> </binding> </netTcpBinding> </bindings> <client> <endpoint contract="Server.IService1" binding="netTcpBinding" address="net.tcp://localhost:8081/Service1.svc"/> <endpoint contract="Server.IService2" binding="netTcpBinding" address="net.tcp://localhost:8081/Service2.svc"/> </client> The server configuration is this: <bindings> <netTcpBinding> <binding portSharingEnabled="true"> <security mode="TransportWithMessageCredential"> <message clientCredentialType="UserName"/> </security> </binding> <binding name="public"> <security mode="Transport"> <message clientCredentialType="Windows"/> </security> </binding> </netTcpBinding> </bindings> <services> <service name="Service1"> <endpoint contract="Server.IService1, Library" binding="netTcpBinding" address=""/> </service> <service name="Service2"> <endpoint contract="Server.IService2, Library" binding="netTcpBinding" address=""/> </service> </services> <serviceHostingEnvironment> <serviceActivations> <add relativeAddress="Service1.svc" service="Server.Service1"/> <add relativeAddress="Service2.svc" service="Server.Service2"/> </serviceActivations> </serviceHostingEnvironment> The thing is that both bindings don't seem to want live together in my host. When I remove either of them, all's fine but together they produce the following exception on the client: The requested upgrade is not supported by 'net.tcp://localhost:8081/Service2.svc'. This could be due to mismatched bindings (for example security enabled on the client and not on the server). In the server trace log, I find the following exception: Protocol Type application/negotiate was sent to a service that does not support that type of upgrade. Am I looking into the right direction or is there a better way to solve this?

I want one of the services to be authenticated differently, because it serves the view model for my logon view. When it's called, the client is obviously not logged on yet. I figure Windows authentication serves best or perhaps just certificate based security (which in fact I should use for the authenticated services as well) if the services are hosted on a machine that is not in the same domain as the web application. That's not the point here though. Using multiple TCP bindings is what's giving me trouble. I tried setting it up like this in my client configuration: <bindings> <netTcpBinding> <binding> <security mode="TransportWithMessageCredential"> <message clientCredentialType="UserName"/> </security> </binding> <binding name="public"> <security mode="Transport"> <message clientCredentialType="Windows"/> </security> </binding> </netTcpBinding> </bindings> <client> <endpoint contract="Server.IService1" binding="netTcpBinding" address="net.tcp://localhost:8081/Service1.svc"/> <endpoint contract="Server.IService2" binding="netTcpBinding" bindingConfiguration="public" address="net.tcp://localhost:8081/Service2.svc"/> </client> The server configuration is this: <bindings> <netTcpBinding> <binding portSharingEnabled="true"> <security mode="TransportWithMessageCredential"> <message clientCredentialType="UserName"/> </security> </binding> <binding name="public"> <security mode="Transport"> <message clientCredentialType="Windows"/> </security> </binding> </netTcpBinding> </bindings> <services> <service name="Service1"> <endpoint contract="Server.IService1, Library" binding="netTcpBinding" address=""/> </service> <service name="Service2"> <endpoint contract="Server.IService2, Library" binding="netTcpBinding" bindingConfiguration="public" address=""/> </service> </services> <serviceHostingEnvironment> <serviceActivations> <add relativeAddress="Service1.svc" service="Server.Service1"/> <add relativeAddress="Service2.svc" service="Server.Service2"/> </serviceActivations> </serviceHostingEnvironment> The thing is that both bindings don't seem to want live together in my host. When I remove either of them, all's fine but together they produce the following exception on the client: The requested upgrade is not supported by 'net.tcp://localhost:8081/Service2.svc'. This could be due to mismatched bindings (for example security enabled on the client and not on the server). In the server trace log, I find the following exception: Protocol Type application/negotiate was sent to a service that does not support that type of upgrade. Am I looking into the right direction or is there a better way to solve this?
