RichEditControl.UnhandledException Event

This event is raised when an unhandled exception of the RichEditControl occurs.

Namespace:DevExpress.XtraRichEdit
Assembly:DevExpress.XtraRichEdit.v17.1.dll

Expanded Syntax

Expanded Event Data

The event handler receives an argument of type RichEditUnhandledExceptionEventArgs containing data related to this event.

The following RichEditUnhandledExceptionEventArgs properties provide information specific to this event.
Property Description
Exception Gets the exception which triggers the UnhandledException event.
Handled Gets or sets whether the exception should be propagated upwards.

Expanded Remarks

The UnhandledException event is helpful when a command is executed via the Bar (Ribbon) user interface, and you are unable to catch the exception which is likely to occur. The most common case is an attempt to save the document to a read-only or locked file. If you do not handle the UnhandledException event, the unhandled exception is thrown and the application crashes. All changes in the document are lost. To prevent this, handle the exception using the following code.
