Property Value
A Uri that refers to the UI that automatically opens when an application starts.You can use StartupUri to automatically load a UI resource when an application starts.
The following table shows the types of UI resources that can be loaded, and the type of window they are opened into, and the type of application that these resources can be set as the StartupUri.
| Type | Window | Application Type |
|---|---|---|
| Window | Window | Standalone Only |
| NavigationWindow | NavigationWindow | Standalone Only |
| Page | NavigationWindow | Standalone/Browser-Hosted |
| UserControl | NavigationWindow | Standalone/Browser-Hosted |
| FlowDocument | NavigationWindow | Standalone/Browser-Hosted |
| PageFunction | NavigationWindow | Standalone/Browser-Hosted |
Typically, you set the StartupUri property declaratively in XAML. However, you can set StartupUri programmatically, such as from a Startup event handler, which is useful if for applications that can only load the necessary UI resources at run time. For example, an application might wait until run time to load its resources if the name of the UI resource is stored in a configuration file.
Whether you set StartupUri declaratively or programmatically, the corresponding UI resource is not loaded until after the Startup event is handled. Consequently, you won't have access to the resulting window from either the Windows property or the MainWindow property when handling Startup.
