ASPxClientHtmlEditor.CallbackError Event

Fires on the client if any server error occurs during server-side processing of a callback sent by the ASPxClientHtmlEditor.

Namespace:DevExpress.Web.ASPxHtmlEditor.Scripts
Assembly:JavaScript

Expanded Syntax

Expanded Event Data

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

The following ASPxClientCallbackErrorEventArgs properties provide information specific to this event.
Property Description
handled Gets or sets whether the event is handled and the default error handling actions are not required.
message Gets the error message that describes the server error that occurred.

Expanded Remarks

The CallbackError event enables you to properly respond to a server error occurring as a result of a callback being processed on the server side. You can handle this event to perform specific client-side actions, such as displaying explanatory text or an image related to the error, for example.

Typically, a server error which occurs during server-side processing of a callback, leads to web application hanging, because, in this case, no proper response is generated for a control that initiated the callback. However, AJAX-enabled web controls from the DevExpress product line are able to automatically catch server errors occurring within handlers of their server-side events, and to pass the related error information to the client for further processing through the CallbackError event's argument.

See Handling Callback Exceptions on Client to learn more.
