public event RichEditInvalidFormatExceptionEventHandler InvalidFormatException
Public Event InvalidFormatException As RichEditInvalidFormatExceptionEventHandler
The InvalidFormatException event's data class is RichEditInvalidFormatExceptionEventArgs. The following properties provide information specific to this event:
| Property | Description |
|---|---|
| Exception | Gets the exception which triggers the InvalidFormatException event. |
Handle the InvalidFormatException event to implement a fallback when there is a risk that corrupted data will be loaded. This event fires after a data check fails for data loaded from a file, from a stream or pasted from the Clipboard.
When you call the RichEditDocumentServer.LoadDocument method, the format of data can be specified explicitly or deduced from the file extension. When a corresponding importer is created, it performs a data check and raises the InvalidFormatException event if it fails.
You can handle the event and perform required actions (inform the end-user) or leave it as is. The event is handled automatically, so no data will be imported and the exception will not propagate further.
