While both of them are working fine from report manager khaled Mohamed

Hi, Wierd though As per my understanding, you are having different pages for different reports. And on the click of the button you redirect to the page and call the report. In such scenario you have to write this code on the page load event of the report page. I mean that you have to write this code on the page where you have drop the Report Viewer control. And in the event were you bind the Report Viewer control with the report. I hope above make sense for you. Please let me know if I misunderstood something. http://forums.asp.net/t/1276717.aspx/1Regards, PS

Hi, No, It is not my case, there is miss understanding I am having only one report viewer control, which accept the parameter form web form control And pass it correctly to my first report, inside my first report there is a hyper link to a second report This hyper link does not work if first report is displayed by Viewer while it work fine when using Report managerkhaled Mohamed

Hi Khaled, From your description, the drillthrough report works on the report manager but it doesnt work in the ReportView control that is embedded in an ASP .NET web application. In the web application, the report parameter gets values from a web form control. If I have something misunderstood, please feel free to let me know. Based on the error message, the issue may be caused by the custom parameter in the web application. At this time, I suggest that you temporarily remove the specific custom web form control and use the built-in parameter toolbar of the ReportViewer control. If the issue persists, I suggest that you call the Update method of the UpdatePanel in the pre-render event of the report viewer: http://stackoverflow.com/questions/3460347/go-to-report-drillthrough-action-not-working-in-ssrs-and-asp-net Hope this helps.

Thank you all Yes I pass the parameter through web control, but this occurred while calling only the first parameter, The second Linked Report accept its parameters either Through First report parameter or First report data set, I mean the second report does not accept its parameter from any web control khaled Mohamed
