  1. AddExtension yöntemini koddan çağırın.
    • Aspose.Cells for Reporting Services dışa aktarma biçimlerini bir Rapor Görüntüleyici denetim örneğine eklemek istediğinizde AddExtension’ı (önceki adımda gösterildiği gibi) çağırabilirsiniz. WinForms veya ASP .NET uygulamasının Form_Load veya Page_Load etkinlik işleyicisinden aramayı düşünün.
    • Tüm veya yalnızca bazı Aspose.Cells for Reporting Services dışa aktarma biçimlerini ekleyebilirsiniz. Rapor Görüntüleyici’de görünecek biçimler için herhangi bir görüntü adı belirtebilirsiniz. Microsoft Rapor Görüntüleyiciye yerel modda Aspose.Cells for Reporting Services dışa aktarma biçimlerini eklemek için aşağıdaki kodu kullanın:

C#

            AddExtension(reportViewer1, "Xls - Xls via Aspose.Cells",    typeof(Aspose.Cells.ReportingServices.XlsRenderer));

            AddExtension(reportViewer1, "Xlsx - Xlsx via Aspose.Cells", typeof(Aspose.Cells.ReportingServices.Excel2007XlsxRenderer));

			AddExtension(reportViewer1, "CSV - CSV via Aspose.Cells",    typeof(Aspose.Cells.ReportingServices.CSVRenderer));

            AddExtension(reportViewer1, "SpreadsheetML - SpreadsheetML via Aspose.Cells", typeof(Aspose.Cells.ReportingServices.SpreadsheetMLRenderer));

            AddExtension(reportViewer1, "Txt - TabDelimited text via Aspose.Cells", typeof(Aspose.Cells.ReportingServices.TabDelimitedRenderer)); 

VB .NET

              AddExtension(reportViewer1, "Xls - Xls via Aspose.Cells",    GetType (Aspose.Cells.ReportingServices.XlsRenderer));

            AddExtension(reportViewer1, "Xlsx - Xlsx via Aspose.Cells", GetType (Aspose.Cells.ReportingServices.Excel2007XlsxRenderer));

			AddExtension(reportViewer1, "CSV - CSV via Aspose.Cells",    GetType (Aspose.Cells.ReportingServices.CSVRenderer));

            AddExtension(reportViewer1, "SpreadsheetML - SpreadsheetML via Aspose.Cells", GetType (Aspose.Cells.ReportingServices.SpreadsheetMLRenderer));

            AddExtension(reportViewer1, "Txt - TabDelimited text via Aspose.Cells", GetType (Aspose.Cells.ReportingServices.TabDelimitedRenderer));
  1. Yeni dışa aktarma biçimlerini test edin.
    1. Uygulamanızı çalıştırın. Microsoft Rapor Görüntüleyici’deki Dışa Aktar menüsünde bulunan bir dizi yeni dışa aktarma biçimini fark etmelisiniz.
    2. Birini seçin ve dışa aktarımı çalıştırın.
    3. Belgenin beklendiği gibi oluşturulduğunu doğrulayın.

Rapor Görüntüleyicide yerel modda çalışırken yeni dışa aktarma formatları görünür hale geldi
