Reusing the ReportViewer and Winform for Multiple reports

[Kerry]

Hello, 

I have a number of reports, I do not wish to create a viewer for each report, can I reuse the same ReportViewer and the winform for multiple reports by creating properties that pass in the Report to instantiate to the Winform.  I've created a separate library for my reports and now wish to instantiate my reports in the one viewer.  Is it good practice to instantiate my Report in a calling form and then pass it to the Winform that holds the viewer, cast it to a (Telerik.Reporting.IReportDocument) object and set the ReportViewers REPORT property.

Thanks,

Kerry

Hello Kerry,

Yes this is correct approach and we do the same in our Visual Studio examples installed with the product.

Hello,

Yes I saw some of the code snippets on the forum which use IReportDocument 
 however I notice that when using IReportDocument we lose access to some of the properties available when instantiating the report such as rpt.ReportParameters["parameterName"].Value and rpt.Datasource etc.  Can you direct me to examples which still use they properties along with IReportDocument.

Thank You,

Kerry

Hello Kerry,

In case you are sure that the viewer would show a single report (not a report book) and you need to access its properties, you can always cast to Telerik.Reporting.Report type and use its respective properties.

H Steve, 

Yes it is a single report however if I cast the variable as the ReportType I get an error trying to cast the same variable as a different ReportType.  I'm trying to achieve this using one block of code in on ReportViewer.

switch (_rptType)
            {
                case 1:
                    rpt = new ClientTrustLedger(eFirmSetting, dbConnect);
                    ClientTrustLedger rpt2 = (ClientTrustLedger)rpt;
                    break;
                case 2:
                    rpt = new DepositSlipReport(eFirmSetting,dbConnect);
                    DepositSlipReport rpt2 = (DepositSlipReport)rpt;
                    rpt2.ReportParameters["DepositNo"].Value = DepositNo;
                    break;
                default:
                    rpt = new ClientTrustLedger(eFirmSetting, dbConnect);
                    break;
            }
            
            this.reportViewer1.Report = rpt2;
            this.reportViewer1.RefreshReport();


If you can direct me to smaple code that would be helpful.

Thanks,


Kerry

Hello Kerry,

There is a much cleaner solution to initialize a report from a predefined list by using reflection, check the attached project.
