public event RoutedEventHandler DocumentLoaded
Public Event DocumentLoaded As RoutedEventHandler
The DocumentLoaded event's data class is RoutedEventArgs. The following properties provide information specific to this event:
| Property | Description |
|---|---|
| Handled | Gets or sets a value that indicates the present state of the event handling for a routed event as it travels the route. |
| OriginalSource | Gets the original reporting source as determined by pure hit testing, before any possible Source adjustment by a parent class. |
| RoutedEvent | Gets or sets the RoutedEvent associated with this RoutedEventArgs instance. |
| Source | Gets or sets a reference to the object that raised the event. |
The event data class exposes the following methods:
| Method | Description |
|---|---|
| InvokeEventHandler(Delegate, Object) | When overridden in a derived class, provides a way to invoke event handlers in a type-specific way, which can increase efficiency over the base implementation. |
| OnSetSource(Object) | When overridden in a derived class, provides a notification callback entry point whenever the value of the Source property of an instance changes. |
The following code snippets (auto-collected from DevExpress Examples) contain references to the DocumentLoaded event.
