I am developing a c# application where I need to generate a report. I am a using a dataset which is filled with the data coming from a stored procedure which takes one parameter from the C# code. I am creating a parameter in report1.rdlc and populating it with the data from a text box. When I run the application I can’t see anything on report viewer. There is no error in my code. Someone please help as this an urgent requirement. I hope this makes sense.

Please review my code below:

public void GenerateBranchwiseReport()
        {
            conn.Open();
            SqlCommand BranchReportcmd = new SqlCommand("select [am/bsi name] from masterlookup where [asc type]='BRANCH' group by [am/bsi name]", conn);
            SqlDataReader BranchReportread = BranchReportcmd.ExecuteReader();
            while (BranchReportread.Read())
            {
                BranchManagerName.Add(BranchReportread.GetValue(0).ToString());
            }
            conn.Close();
            foreach (string managername in BranchManagerName)
            {
                conn.Open();
                SqlCommand GetReportDatacmd = new SqlCommand();
                GetReportDatacmd.CommandText = "USP_BranchwiseReport";
                GetReportDatacmd.CommandType = CommandType.StoredProcedure;
                GetReportDatacmd.Parameters.Add(new SqlParameter("@BranchManagerName", managername));
                GetReportDatacmd.Connection = conn;
                GetReportDatacmd.ExecuteNonQuery();
                SqlDataAdapter da = new SqlDataAdapter(GetReportDatacmd);
                DataSet ds = new DataSet();
                da.Fill(ds);
                conn.Close();
                reportViewer1.Reset();
                this.reportViewer1.Visible = true;
                string reportname = @"d:\users\administrator\documents\visual studio 2010\Projects\ReportwithParameter\ReportwithParameter\Report1.rdlc";
                this.reportViewer1.LocalReport.ReportPath = @"d:\users\administrator\documents\visual studio 2010\Projects\ReportwithParameter\ReportwithParameter\Report1.rdlc";
                ReportParameter[] param = new ReportParameter[1];
                param[0] = new ReportParameter("ManagerName", managername);
                this.reportViewer1.LocalReport.SetParameters(param);
                ReportDataSource ReportBranch = new ReportDataSource("DatasetWithParameter.USP_BranchwiseReport", ds.Tables[0]);
                this.reportViewer1.LocalReport.ReportEmbeddedResource = reportname;
                this.reportViewer1.LocalReport.DataSources.Clear();
                this.reportViewer1.LocalReport.DataSources.Add(new Microsoft.Reporting.WinForms.ReportDataSource("DatasetWithParameter.USP_BranchwiseReport", ds.Tables[0]));
                //this.reportViewer1.LocalReport.DataSources.Add(ReportBranch);
                this.reportViewer1.LocalReport.Refresh();
                //SendEmail();
            }
        }
