Enables you to handle server-side errors in the Web Report Designer.

Namespace: DevExpress.XtraReports.Web.ReportDesigner.Services

Assembly: DevExpress.XtraReports.v19.2.Web.dll

Declaration

public class ReportDesignerExceptionHandler :
    ExceptionHandler,
    IReportDesignerExceptionHandler,
    IExceptionHandler
Public Class ReportDesignerExceptionHandler
    Inherits ExceptionHandler
    Implements IReportDesignerExceptionHandler,
               IExceptionHandler

Remarks

The ReportDesignerExceptionHandler class provides the following methods:

The code snippet below demonstrates how to create a descendant from this class and override the GetUnknownExceptionMessage method to return an actual exception message.

using System;
using DevExpress.XtraReports.Web.ReportDesigner.Services;

public class CustomReportDesignerExceptionHandler : ReportDesignerExceptionHandler {
    public override string GetUnknownExceptionMessage(Exception ex) {
        return ex.Message;
    }
}

To register the implemented exception handler, use the static DefaultReportDesignerContainer.Register method at the application's startup as shown below:

void Application_Start(object sender, EventArgs e) {
    // ...
    DevExpress.XtraReports.Web.ReportDesigner.DefaultReportDesignerContainer.
        Register<IReportDesignerExceptionHandler, CustomReportDesignerExceptionHandler>();
}
