UI Add-In That Binds to Host Data Sample

  • Article

This sample demonstrates how to create an add-in pipeline, using the .NET Framework 3.5 add-in model, that enables a WPF host application to do the following:

  1. Host a UI add-in.

  2. Bind the UI add-in's UI to data provided by the WPF host application.

In this sample, there are three add-ins, and each returns a UI to the WPF host as the result of a method call. The method call accepts the host-provided data object as the argument and, ultimately, the add-in UI is bound to the data object. Two add-ins are read-only visualizations of the bound data while one is an editable visualization. When the data object is updated in the host application, property change notification is communicated through the add-in pipeline to all add-ins in order to update their UIs accordingly. Likewise, when the data object is updated by the editable add-in UI, the changes are communicated to the host application and any other add-in UIs bound to the data object. Ultimately, the data in the host application and the add-in UIs stays in sync.

For more information about the programming model that is demonstrated by this sample, see Windows Presentation Foundation Add-Ins Overview.

This sample demonstrates a specific feature of the Windows Presentation Foundation and, consequently, does not follow application development best practices.
