Hello. I'm developing in Silverlight VB an app that is using SSRS. The report is already created, so, I have my file.rdl. I uploaded to SSRS, configured the data sources and set all those details.. Right now, I'm trying to show the report from my app. My app built the right url http://localhost:6556/Reports/Report1/rptReport.aspx?Address=0&AdressName= &Start=1950/01/01&End=2012/07/24&Coworker=0&CoworkerName= but the SSRS dont find out. Then, it shows " http://SERVER/Default.aspx?aspxerrorpath=/SERVER/Reports/Report1/rptReport.aspx " Someone can help me?

Hi, In the URL, you provided there is no report name exist, looks like you are passing parameters and your last parameter does not have value. If you are opening the server URL not RDLC, then URL can like this http://localhost:6556/ReportServer/Pages/ReportViewer.aspx?%2fReportName.RDL - Chintak (My Blog)

Hello shirivo, Thank you to post your question on TechNet forum. I want to check whether you can access http://SERVER/Reports/Report1/rptReport.aspx. Is this your custom report page? If so, please provide us the following things. What is the design of the page? Please take a screenshot of the page designer.What is the logic of the page? Can you share us the code segment about the code?Can you disable the custom error and let it output the callstack and .net default error page? Therefore, we can capture some information about this issue. If you have any concerns, please tell us freely. Regards, EdwardEdward Zhu TechNet Community Support
