问题 I have some RDL reports created with SQL Server BI Development Studio and now I need to render them using the ASP.NET Report Viewer. Even though my RDLs contain references to the SQL server and the SELECT query, it keeps saying I need to specify a datasource for the report. Is there a way to make the datasource from the RDL be used or do I have to pass a datasource to the report viewer via C# code? Thank you. 回答1: Did you verify the DataSourceReference element in your RDL? It needs the path

问题 How to configure ReportViewer so it can be exported CSV in ASP.NET (ReportViewer that comes from VisualStudio 2005/2008)? So it will be apart of current drop downlist? At the moment, it's only for Excel and PDF but not CSV. Thanks 回答1: When you run Report Viewer in Local mode, you cannot export to anything other than PDF and Excel. If you want to be able to export to other formats, you need to run Report Viewer in Server Mode. The rendering is then done on the SQL server through extensions.

One of my columns represent a decimal value from a SQL database, for example: 5199.9800 and at the end of this column, all the amounts are summed.

问题 How do we set the parameters of .Net's reportviewer? 回答1: List<ReportParameter> paramList = new List<ReportParameter>(); paramList.Add(new ReportParameter("ClientName", clientName, false)); TheReportObject.LocalReport.SetParameters(paramList); And you have to make sure you define the same named parameters inside the report definition as well. 来源： https://stackoverflow.com/questions/637464/set-reportviwers-parameter-in-an-application

问题 I'm using MS Report Viewer 10 in VS 2013; the project is being upgraded from VS 2010. I have worked through a series of issues relating to Report Viewer, and have the control itself up and running. I have a number of reports in SSRS, and I have confirmed that the reports themselves work properly. I have a Web Forms ASPX page for data input. It passes data via JSON to a popup ASPX page that contains the Report Viewer control. I am running IIS Express 7, SQL Server 2008 R2 (v10.50), and a

问题 I'd like to know if it is possible to set the Excel output as "Locked", in the sense that when we try to change a Cell's value, then there will be a warning indicating that we can not change it unless we remove the Sheet's protection. I know that we can develop a custom Excel automation code, and set a Password to protect the sheet just before we save it. But, is there any easy way to accomplish this using ReportViewer's built-in feature? 回答1: After doing some research, I've managed to find
