Assembly: DevExpress.XtraReports.v20.2.dll

NuGet Packages: DevExpress.Reporting.Core, DevExpress.WindowsDesktop.Reporting.Core

Declaration

public class ReportGalleryDirectoryExtension :
    ReportGalleryExtension

VB.NET

Public Class ReportGalleryDirectoryExtension
    Inherits ReportGalleryExtension

Remarks

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

  C#

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

  VB.NET

  Imports System.IO
  Imports DevExpress.XtraReports.Extensions
  
  ' ...
  Dim path As String = Path.Combine(Path.GetDirectoryName(Application.ExecutablePath), "ReportGallery.xml")
  ReportGalleryExtension.RegisterExtensionGlobal(New ReportGalleryDirectoryExtension(path))
  

• WPF

  C#

  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);
  

  VB.NET

  Imports System
  Imports System.IO
  Imports DevExpress.XtraReports.Extensions
  
  ' ...
  Private path As String = Path.Combine(Path.GetDirectoryName(AppDomain.CurrentDomain.BaseDirectory), "ReportGallery.xml")
  reportDesigner.ReportGalleryOptions.Storage = New ReportGalleryDirectoryExtension(path)
