Abstract: 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.

Abstract: 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.

Abstract: A list control allows for a harmonized display of heterogeneous list element data by using at least two templates. The templates define the layout for the list element data. The templates consult an interface while calculating the layout. The interface provides information regarding the location of at least one gridline; the layout for the list element data is based on that location. The list control implements the interface, thus allowing heterogeneous templates to rely one interface providing on one gridline location. In order to take into account the requirements of each list element for gridline location, the interface requests information regarding a preliminary gridline location for each list element and bases the final gridline location on this information.

Abstract: A framework for individually controlling the layout of display elements provides management of the layout automatically via pluggable policies. Control modules are dedicated to controlling the format of respective display elements. The control modules are organized into an ancestral hierarchy tree structure. Each parent control module specifies a policy object that manages the layout of its children, and provides measurement information to ancestor control modules. When an aspect of a control module changes that will affect its layout, it makes a single call which causes the framework to utilize the relevant layout managers to layout any affected control modules.
