## Remarks
The only way to cancel the asynchronous operation of this method is to cancel all asynchronous operations. Contrast this with the other overload of this method: <xref:System.Windows.Documents.DocumentPaginator.ComputePageCountAsync%28System.Object%29>.
This method stores in the task it returns all non-usage exceptions that the method's synchronous counterpart can throw. If an exception is stored into the returned task, that exception will be thrown when the task is awaited. Usage exceptions, such as <xref:System.ArgumentException>, are still thrown synchronously. For the stored exceptions, see the exceptions thrown by <xref:System.Windows.Documents.DocumentPaginator.ComputePageCount>.

## Remarks
The only way to cancel the asynchronous operation of this method is to cancel all asynchronous operations. Contrast this with the other overload of this method: <xref:System.Windows.Documents.DocumentPaginator.GetPageAsync%28System.Int32%2CSystem.Object%29>.
This method raises the <xref:System.Windows.Documents.DocumentPaginator.GetPageCompleted> event. The <xref:System.Windows.Documents.DocumentPage> is passed to the event as one of the event arguments. See <xref:System.Windows.Documents.DocumentPaginator.GetPageAsync%28System.Int32%2CSystem.Object%29> for how to use this method to get the page.
This method stores in the task it returns all non-usage exceptions that the method's synchronous counterpart can throw. If an exception is stored into the returned task, that exception will be thrown when the task is awaited. Usage exceptions, such as <xref:System.ArgumentException>, are still thrown synchronously. For the stored exceptions, see the exceptions thrown by <xref:System.Windows.Documents.DocumentPaginator.GetPage(System.Int32)>.

## Remarks
This overload of the method makes it possible to cancel this asynchronous operation without cancelling all asynchronous operations.
This method raises the <xref:System.Windows.Documents.DocumentPaginator.GetPageCompleted> event. The <xref:System.Windows.Documents.DocumentPage> is passed to the event as one of the event arguments.
The following steps illustrate how to retrieve a <xref:System.Windows.Documents.DocumentPage> asynchronously:
1. Create a <xref:System.Windows.Documents.GetPageCompletedEventHandler> delegate and add it to be notified of <xref:System.Windows.Documents.DocumentPaginator.GetPageCompleted> events.
2. Call <xref:System.Windows.Documents.DocumentPaginator.GetPageAsync%28System.Int32%2CSystem.Object%29> specifying the `pageNumber` desired and a unique `userState`, which will be used to identify the completion of the asynchronous event.
3. When the event occurs and the delegate is called, compare the event's <xref:System.Windows.Documents.GetPageCompletedEventArgs>.<xref:System.ComponentModel.AsyncCompletedEventArgs.UserState%2A> property with the original <xref:System.Windows.Documents.DocumentPaginator.GetPageAsync%28System.Int32%2CSystem.Object%29> `userState` parameter. (The <xref:System.Windows.Documents.GetPageCompletedEventArgs>.<xref:System.Windows.Documents.GetPageCompletedEventArgs.PageNumber%2A> property will also match the `pageNumber` specified in the <xref:System.Windows.Documents.DocumentPaginator.GetPageAsync%28System.Int32%2CSystem.Object%29> call.)
4. When the <xref:System.Windows.Documents.GetPageCompletedEventArgs>.<xref:System.ComponentModel.AsyncCompletedEventArgs.UserState%2A> property matches the original <xref:System.Windows.Documents.DocumentPaginator.GetPageAsync%28System.Int32%2CSystem.Object%29> `userState`, the operation is complete and the page is ready.
5. Call <xref:System.Windows.Documents.DocumentPaginator.GetPage%2A> to retrieve the formatted <xref:System.Windows.Documents.DocumentPage>.
