  1. Appelez la méthode AddExtension depuis le code.
    • Vous pouvez appeler AddExtension (comme indiqué dans l’étape précédente) chaque fois que vous avez besoin d’ajouter des formats d’exportation Aspose.Cells for Reporting Services à une instance de contrôle Report Viewer. Considérez l’appeler depuis le gestionnaire d’événements Form_Load ou Page_Load d’une application WinForms ou ASP .NET.
    • Vous pouvez ajouter tous ou seulement certains des formats d’exportation Aspose.Cells for Reporting Services. Vous pouvez spécifier un nom d’affichage pour les formats à apparaître dans Report Viewer. Pour ajouter des formats d’exportation Aspose.Cells for Reporting Services à Microsoft Report Viewer en mode local, utilisez le code suivant :

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. Testez les nouveaux formats d’exportation.
    1. Exécutez votre application. Vous devriez remarquer un certain nombre de nouveaux formats d’exportation disponibles dans le menu Export dans le Visualiseur de rapports.
    2. Sélectionnez l’un des formats et lancez l’exportation.
    3. Vérifiez que le document est créé comme vous l’attendiez.

De nouveaux formats d’exportation apparaissent dans le Visualiseur de rapports en mode local
