how to open ssrs report from asp web page using report viewer

问题

I'm trying to open an ssrs report on my web pages using ReportViewer. For the Report Serverl URL I have:

http://db_servers/ReportsServer_SENSORSQLSERVER

and for my report path I have:

http://db_servers/ReportsServer_SENSORSQLSERVER/Pages/ReportViewer.aspx?%2fCustomer1&rs:Command=Render.

I have looked through many sites and tutorial on how to add URL but I still get an error saying: The length of my link must be below 260 characters long. (rsInvalidItemPath). I also want to mention that my report server is in Native mode. My report server is located in another computer so I made sure the processing mode on my report viewer is remote. Whenever I go to the surver url I can clearly see the list of my reports and when I click on a report I can see it as well so I know my urls are correct. I have tried including a slash in front of my report path url, replacing "2%f" with a space. Nothing seems to work. Any idea? Thanks.

You need to separate out the URL to the server, report path and add the parameters to a parameters array.

Here's a sample:

    protected void Page_Init(object sender, EventArgs e)
{
    if (!Page.IsPostBack)
    {
        // Set the processing mode for the ReportViewer to Remote
        reportViewer.ProcessingMode = ProcessingMode.Remote;

        ServerReport serverReport = reportViewer.ServerReport;

        // Set the report server URL and report path
        serverReport.ReportServerUrl =
            new Uri("http://<Server Name>/reportserver");
        serverReport.ReportPath =
            "/AdventureWorks Sample Reports/Sales Order Detail";

        // Create the sales order number report parameter
        ReportParameter salesOrderNumber = new ReportParameter();
        salesOrderNumber.Name = "SalesOrderNumber";
        salesOrderNumber.Values.Add("SO43661");

        // Set the report parameters for the report
        reportViewer.ServerReport.SetParameters(
            new ReportParameter[] { salesOrderNumber });
    }
}

You should replace the "2%f" by "/".

The problem is with your ReportPath property, e.g:

%2fCustomer1 -> /Customer1

Very simple method to open SSRS :

                string reportName = "TestReport";
                string displayName = reportName;
                bool isDomainAuthentication = false;

                var reportParameters = new List<ReportParameter>();
                reportParameters.AddRange((List<ReportParameter>)Session["ReportParameters"]);

                string ReportServerURL = "http://DESKTOP38/ReportServer_SQLEXPRESS";
                reportViewer1.ServerReport.ReportServerUrl = new Uri(ReportServerURL);
                reportViewer1.ServerReport.ReportPath = "FolderName" + reportName;
                reportViewer1.ServerReport.DisplayName = displayName;
                reportViewer1.ShowPrintButton = true;
                reportViewer1.ShowToolBar = true;
                reportViewer1.ShowCredentialPrompts = false;

                if (!isDomainAuthentication)
                {
                    string userId = "DESKTOP38"; //Username
                    string password = "test";
                    string domain = ReportServerURL;

                    IReportServerCredentials reportCredentials = new ReportServerCredentials(userId, password, domain);
                    reportViewer1.ServerReport.ReportServerCredentials = reportCredentials;
                }
                if (reportParameters != null)
                {
                    reportViewer1.ServerReport.SetParameters(reportParameters);
                }
                this.reportViewer1.ServerReport.Refresh();
