IWebDocumentViewerExportResultUriGenerator Interface

In This Article

Allows you to override the default URI that a browser uses to get an export result.

Namespace: DevExpress.XtraReports.Web.WebDocumentViewer

Assembly: DevExpress.XtraReports.v24.2.Web.dll

NuGet Package: DevExpress.Web.Reporting.Common

#Declaration

public interface IWebDocumentViewerExportResultUriGenerator

#Remarks

Use the IWebDocumentViewerExportResultUriGenerator service in web applications with header-token authentication to print and export documents if you need to display an export result on a separate page.

On the server side, all requests are processed by a single endpoint:

When you use header-token authentication in your application, this single endpoint is protected (for instance, with a Bearer token). A web browser cannot obtain the export and print results, because the browser’s requests have no headers and cannot be authenticated.

To enable a browser to get export results, do the following:

  1. Configure another endpoint with a custom protection mechanism instead of header-token authentication.

  2. Implement the IWebDocumentViewerExportResultUriGenerator interface and return a custom URI in the CreateUri method. For instance, save an exported document to any storage and return the URI to access this document from the client side.

  3. Register the service at the application startup.

You can also use the IWebDocumentViewerExportResultUriGenerator service to generate a more readable and user-friendly URI. Web browsers display the information obtained from this URI in the tab header.

Note
