Event that occurs when the factory finishes loading the document successfully or otherwise.
public event EventHandler<LoadAsyncCompletedEventArgs> Completed
public:
event EventHandler<Leadtools::Documents::LoadAsyncCompletedEventArgs^>^ Completed
def Completed(sender,e): # sender: LoadDocumentAsyncOptions e: LoadAsyncCompletedEventArgs
Completed will occur once when the factory finishes loading the document successfully or otherwise. It uses the LoadAsyncCompletedEventArgs event data class that is populated with the following:
Member | Value |
---|---|
true if the user has aborted the current operation, false otherwise.. |
|
The same value originally set by the user in LoadDocumentAsyncOptions.UserState. |
|
The error object thrown if any. |
|
The location of the document loaded. This is the uri value passed to LoadFromUriAsync |
|
The result LEADDocument object if the load operation was successful, null otherwise |
