All applications tend to share a common set of functionality that applies to application implementation and management. This topic provides an overview of the functionality in the Application class for creating and managing applications. In WPF, common application-scoped functionality is encapsulated in the Application class.
To access controls in another WPF forms, you have to declare that control as public. The default declaration for controls in WPF is public, but you can specify it with this code: And after that you can search in all active windows in the application to find windows that have control like this:
In WPF, a window is encapsulated by the Window class that you use to do the following: Display a window. Configure the size, position, and appearance of a window. Host application-specific content. Manage the lifetime of a window. The following figure illustrates the constituent parts of a window:
This allows the code-behind file to be associated with the partial class that is generated for the markup file when the application is built, for more information, see Compile a WPF Application. In code-behind, the Window class must implement a constructor that calls the InitializeComponent method.
Yes sure. You can access it everywhere in a WPF application.
// assuming that you derivate of Application is named App ((App)Application.Current).SomePropertyOfApp = ... Yes - it's as easy as Application.Current.
