RichEditDocumentServer.InvalidFormatException Event

Fires when the supplied data could not be recognized as data in the assumed format for import.

Namespace: DevExpress.XtraRichEdit

Assembly: DevExpress.RichEdit.v19.1.Core.dll


public event RichEditInvalidFormatExceptionEventHandler InvalidFormatException

Event Data

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.

The following code snippet (auto-collected from DevExpress Examples) contains a reference to the InvalidFormatException event.


The algorithm used to collect these code examples remains a work in progress. Accordingly, the links and snippets below may produce inaccurate results. If you encounter an issue with code examples below, please use the feedback form on this page to report the issue.
