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.v21.2.Core.dll

Declaration

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.

Remarks

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.
