public event RoutedEventHandler AsyncOperationCompleted
Public Event AsyncOperationCompleted As RoutedEventHandler
The AsyncOperationCompleted 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 GridControl fires the AsyncOperationCompleted event after asynchronous data loading is complete in Instant Feedback UI Mode. Use the IsAsyncOperationInProgress property to check the status of the load operation.
The GridControl fires the AsyncOperationStarted event after asynchronous data loading has been started.
