  1. Kopiera och klistra in följande AddExtension-metod i projektet. Den här metoden lägger till det angivna renderingstillägget till listan över tillägg som stöds i Microsoft Report Viewer med hjälp av privat reflektion.

using Microsoft.ReportingServices.ReportRendering;

// Use one of the two namespaces below depending on whether you are developing

// a WinForms or WebForms application.

  1. Anropa AddExtension-metoden från koden. Du kan anropa AddExtension (visas i föregående steg) när du behöver lägga till Aspose.Cells for Reporting Services exportformat till en Report Viewer-kontrollinstans. Överväg att ringa från formuläret_Ladda eller sida_Ladda händelsehanterare för en WinForms- eller ASP .NET-applikation.
  • Du kan lägga till alla eller bara vissa exportformat Aspose.Cells for Reporting Services. Du kan ange vilket visningsnamn som helst för formaten som ska visas i rapportvisaren. För att lägga till Aspose.Cells for Reporting Services exportformat till Microsoft Report Viewer i lokalt läge, använd följande kod:

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. Testa de nya exportformaten.
  2. Kör din applikation. Du bör lägga märke till ett antal nya exportformat tillgängliga iExportera menyn i Report Viewer.
  3. Välj ett av formaten och kör export.
  4. Kontrollera att dokumentet har skapats som du förväntade dig.

Nya exportformat visas i Report Viewer som körs i lokalt läge
