Binding a list in @RequestParam
Or you could just do it that way: public String controllerMethod(@RequestParam(value=”myParam[]”) String[] myParams){ …. } That works for example for forms like this: <input type=”checkbox” name=”myParam[]” value=”myVal1″ /> <input type=”checkbox” name=”myParam[]” value=”myVal2″ /> This is the simplest solution 🙂
AngularJS : The correct way of binding to a service properties
Consider some pros and cons of the second approach: 0 {{lastUpdated}} instead of {{timerData.lastUpdated}}, which could just as easily be {{timer.lastUpdated}}, which I might argue is more readable (but let’s not argue… I’m giving this point a neutral rating so you decide for yourself) +1 It may be convenient that the controller acts as a … Read more
Android Data Binding using include tag
The problem is that the included layout isn’t being thought of as a data-bound layout. To make it act as one, you need to pass a variable: buttons.xml: <layout xmlns:andr…> <data> <variable name=”foo” type=”int”/> </data> <Button android:id=”@+id/button” ….” /> main.xml: <layout xmlns:andr… … <include layout=”@layout/buttons” android:id=”@+id/buttons” app:foo=”@{1}”/> …. Then you can access buttons indirectly through … Read more
Difference between Observer, Pub/Sub, and Data Binding
There are two major differences between Observer/Observable and Publisher/Subscriber patterns: Observer/Observable pattern is mostly implemented in a synchronous way, i.e. the observable calls the appropriate method of all its observers when some event occurs. The Publisher/Subscriber pattern is mostly implemented in an asynchronous way (using message queue). In the Observer/Observable pattern, the observers are aware … Read more
What is two way binding?
Two-way binding just means that: When properties in the model get updated, so does the UI. When UI elements get updated, the changes get propagated back to the model. Backbone doesn’t have a “baked-in” implementation of #2 (although you can certainly do it using event listeners). Other frameworks like Knockout do wire up two-way binding … Read more
Binding to static property
If the binding needs to be two-way, you must supply a path. There’s a trick to do two-way binding on a static property, provided the class is not static : declare a dummy instance of the class in the resources, and use it as the source of the binding. <Window.Resources> <local:VersionManager x:Key=”versionManager”/> </Window.Resources> … <TextBox … Read more
KnockOutJS – Multiple ViewModels in a single View
Knockout now supports multiple model binding. The ko.applyBindings() method takes an optional parameter – the element and its descendants to which the binding will be activated. For example: ko.applyBindings(myViewModel, document.getElementById(‘someElementId’)) This restricts the activation to the element with ID someElementId and its descendants. See documentation for more details.
How to bind an enum to a combobox control in WPF?
You can do it from code by placing the following code in Window Loaded event handler, for example: yourComboBox.ItemsSource = Enum.GetValues(typeof(EffectStyle)).Cast<EffectStyle>(); If you need to bind it in XAML you need to use ObjectDataProvider to create object available as binding source: <Window x:Class=”YourNamespace.MainWindow” xmlns=”http://schemas.microsoft.com/winfx/2006/xaml/presentation” xmlns:x=”http://schemas.microsoft.com/winfx/2006/xaml” xmlns:System=”clr-namespace:System;assembly=mscorlib” xmlns:StyleAlias=”clr-namespace:Motion.VideoEffects”> <Window.Resources> <ObjectDataProvider x:Key=”dataFromEnum” MethodName=”GetValues” ObjectType=”{x:Type System:Enum}”> <ObjectDataProvider.MethodParameters> <x:Type … Read more
Binding a WPF ComboBox to a custom list
You set the DisplayMemberPath and the SelectedValuePath to “Name”, so I assume that you have a class PhoneBookEntry with a public property Name. Have you set the DataContext to your ConnectionViewModel object? I copied you code and made some minor modifications, and it seems to work fine. I can set the viewmodels PhoneBookEnty property and … Read more
