ReportGalleryDirectoryExtension Class

Enables you to provide a custom file storage for the Report Gallery in WinForms and WPF applications.

Namespace: DevExpress.XtraReports.Extensions

Assembly: DevExpress.XtraReports.v23.2.dll

NuGet Package: DevExpress.Reporting.Core


public class ReportGalleryDirectoryExtension :


The Report Gallery stores templates in the %localappdata%\Developer Express Inc\XtraReports Suite\ReportGallery.xml file.

You can use the ReportGalleryDirectoryExtension class to provide a custom file storage. This class is inherited from the abstract ReportGalleryExtension class.

Do the following to store the Report Gallery’s templates in another file:

  1. Create a new ReportGalleryDirectoryExtension class instance and pass the full file path as the constructor parameter.
  2. Pass this instance to the static ReportGalleryExtension.RegisterExtensionGlobal method.

The code below demonstrates how to store templates in the directory that contains the application’s executable file.

  • WinForms

    using System.IO;
    using DevExpress.XtraReports.Extensions;
    // ...
    string path = Path.Combine(Path.GetDirectoryName(Application.ExecutablePath), "ReportGallery.xml");
    ReportGalleryExtension.RegisterExtensionGlobal(new ReportGalleryDirectoryExtension(path));
  • WPF

    using System;
    using System.IO;
    using DevExpress.XtraReports.Extensions;
    // ...
    string path = Path.Combine(Path.GetDirectoryName(AppDomain.CurrentDomain.BaseDirectory), "ReportGallery.xml");
    reportDesigner.ReportGalleryOptions.Storage = new ReportGalleryDirectoryExtension(path);
