    • Described is a system and method for controlling user interface (UI) properties with data. An application is separated into independent parts, a logic portion and a UI portion. The logic portion manipulates data values within the application. The UI portion is responsible for displaying UI properties. A binding specification describes a relationship between the UI property and the data value. The binding specification is used by system level code to determine the manner in which it is notified when the data value undergoes a change and the manner in which it directs the UI portion to reflect the change in the UI property. The binding specification identifies a source data item, a path to the data value in the source data item, a target UI element, and the UI property on the target UI element. The binding may be specified using code or markup language.
    • 描述了一种用于使用数据控制用户界面(UI)属性的系统和方法。 应用程序分为独立部分,逻辑部分和UI部分。 逻辑部分操作应用程序内的数据值。 UI部分负责显示UI属性。 绑定规范描述了UI属性和数据值之间的关系。 系统级代码使用绑定规范来确定数据值发生变化时通知的方式,以及指导UI部分反映UI属性变化的方式。 绑定规范标识源数据项,源数据项中数据值的路径,目标UI元素和目标UI元素上的UI属性。 绑定可以使用代码或标记语言来指定。

    • A program platform performs data binding process between a user interface and data for display. The invention decouples the user interface and the data, along with its application logic, by providing a mechanism for binding data to the user interface. Dependency property binding allows for binding of data with dynamic properties of an element of a data-programming model of a platform. A fallback value is a user-supplied value that can be used when the binding cannot produce a value from an associated data source. Priority Bindings allow a list of bindings that can become active when other, previous bindings fail.
    • 程序平台在用户界面和数据之间执行数据绑定过程以进行显示。 本发明通过提供用于将数据绑定到用户界面的机制来解耦用户界面和数据及其应用逻辑。 依赖属性绑定允许数据与平台的数据编程模型的元素的动态属性绑定。 回退值是用户提供的值,当绑定无法从关联的数据源生成值时可以使用该值。 优先级绑定允许在其他先前绑定失败时可以变为活动的绑定列表。
