binding

问题 I have a listview which loads its data from sqlite database. Each row in listview has image , textview and a checkbox. The sqlitedatabase rows has image and text data + some other columns. My question is can I bind my listview with the database so that all rows will be loaded with required data automatically. (image + textview) There are examples to bind a simple list of textviews. What about complex rows ? Also there are few spinners which can filter the data in list depending on its value.

问题 I need help creating a null -safe BooleanBinding . It has to be null -safe since I can not provide default values for all attributes in the model (one reason: the model contains enumerations). My first approach has been as follows: executeButtonDisabled.bind(missionProperty().isNotNull().and(missionProperty().get().statusProperty().isNotEqualTo(MissionStatus.CREATED))); final BooleanBinding isNotExecutingBinding = missionProperty().isNotNull().and(missionProperty().get().statusProperty()

问题 This may get a tad long, but here goes. I have created a small, wizard-style sample app using the MVVM pattern (basically a dumbed-down version of the code in my "real" app). In this app, the main window moves from through a List<..> of view models, with each view model displaying its associated view. I have 2 view model classes that are essentially identical, and they display the same view. On the view is a combo box, populated with an array of float. The SelectedItem is bound to a float

问题 I have created a user control with collection property: public static readonly DependencyProperty MyListProperty = DependencyProperty.Register( "MyList", typeof(ObservableCollection<Test>), typeof(UserControl1), new FrameworkPropertyMetadata(new ObservableCollection<Test>()) ); public ObservableCollection<Test> MyList { get { return (ObservableCollection<Test>)base.GetValue(MyListProperty); } set { base.SetValue(MyListProperty, value); } } public static readonly DependencyProperty BProperty =

问题 I'm pulling my hair out on this one... I have a view with some grids, a store and a viewModel. I need different filtered versions of the store in different grids, so I'm trying to bind each filtered store to a grid. Now I can't even get a store to load in a grid in the first place... Here's what my code looks like: Store: Ext.define('My.store.Admin.Kinder', { extend: 'Ext.data.Store', model: 'My.model.Kind', storeId: 'adminKinderStore', alias: 'store.adminKinder', proxy: { type: 'ajax',

问题 if i have a master page that binds with ObjectA and then a View that binds with ObjectB, how does that work (or does it work at all) in asp.net mvc. master page might have: Inherits="System.Web.Mvc.ViewMasterPage<CalendarEvent[]>" %> and one of the view might have: Inherits="System.Web.Mvc.ViewPage<Tournament[]>" %> what would you pass into the view from the controller since there are 2 models in this case you are binding to? is this bad practice to have the master page have a binding object?
