  1. استدعاء الأسلوب AddExtension من التعليمات البرمجية. يمكنك استدعاء AddExtension (كما هو موضح في الخطوة السابقة) متى احتجت إلى إضافة تنسيقات تصدير Aspose.Cells for Reporting Services إلى مثيل عنصر تحكم عارض التقارير. ضع في اعتبارك الاتصال من النموذج_تحميل أو صفحة_تحميل معالج الحدث لتطبيق WinForms أو ASP .NET.
  • يمكنك إضافة جميع تنسيقات التصدير Aspose.Cells for Reporting Services أو بعضها فقط. يمكنك تحديد أي اسم عرض للتنسيقات لتظهر في عارض التقارير. لإضافة تنسيقات تصدير Aspose.Cells for Reporting Services إلى عارض تقرير Microsoft في الوضع المحلي ، استخدم الكود التالي:

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));
