摘要:
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.

In an implementation of data association, a data item has a data item property with an associated value and a user interface element has an element property with a value that can be defined by an association to the data item property. A binding definition associates the element property of the user interface element with the data item property such that an application program which generates a user interface for display can be developed independent of the data item, and such that the data item can be developed independent of display-related information corresponding to the user interface element.

Priority binding enables a one-to-many mapping of a target to a source without requiring complex code development by the specification of one or more binding statements. During runtime, these bindings are evaluated. The highest priority binding that evaluates successfully is executed, controlling the two-way transfer of information between source and target. During execution, all possible data binding pathways are monitored. If a binding that has a higher priority than the existing binding evaluates successfully, the existing binding is terminated and the new binding is executed.

A data-binding engine is used to perform command binding. A data binding engine binds user interface controls such as buttons, menus, list boxes, etc. to commands exposed on an application model. A data source and data binding path may be specified in a markup language that defines how the commands are bound to UI elements.

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.

Systems and methods for providing and associating or combining visual style information with data content. The present invention relates to associating a shared set of style information with two or more objects or items that are to be displayed as part of a list or some other visual grouping of the items. By sharing the style information, i.e., the visual representation characteristics information, a program developer need only define the style information or style once. Upon defining the style, the developer can declaratively associate all the items in the list or group with the defined style.

An improved system and method for styling content in a graphical user interface control is provided. An application may define a user interface control having a data object of any type of singular content, including another user interface control. An application may include style declarations that may associate a style resource with the user interface control and a style resource may be dynamically selected for presenting the data object of the user interface control. The style resources may define property values that may be selectively applied to specify a visual representation for the user interface control and data object, such as a visual subtree. A visual representation of the user interface control with the data object may be generated and then a display representation may be rendered for presentation on a user interface display.

Aspects of the subject matter described herein relate to generating and propagating commands. In aspects, elements of a graphical user interface may include an input binding which associates a gesture with a command. When a gesture is received, the command is generated depending on which element has focus. In addition, elements of the graphic user interface may also define methods to call when commands are received. When an event or a command is received, a hierarchical data structure of elements representable on the graphical user interface may be traversed to respond to the event or command.
摘要:
An improved system and method for displaying a user interface object using an associated style is provided. To this end, an application may include style declarations that may associate a style resource with a user interface object. The style resource may define property values that may be selectively applied to a user interface object, may specify a visual representation for the user interface object, such as a visual subtree, and may specify additional property values to be conditionally applied to a user interface object. A styling engine may be provided for applying a style resource to a user interface object. A visual representation of the user interface objects with the applied property values may be generated and then a display representation may be rendered for presentation on a user interface display.
