#Remarks
The OnServerError event is raised on the client side each time a server-side error occurs. Handle this event to perform required actions when a Fetch request completes with an error. When implementing a handling function, use the objects passed as parameters. The first parameter passes the event sender that is the ClientReportDesigner object. The second one is an object with the following field exposed:
- Error
Provides information about a server-side error.
The following code snippet demonstrates how to show an alert box when any internal server error occurs.
