这是参考我之前的问题“Report not showing up on report viewer”
我正在开发一个c#应用程序,我需要生成一个报告。我正在使用一个数据集,该数据集充满了来自存储过程的数据,该存储过程从C#代码中获取一个参数。我在report1.rdlc中创建一个参数,并用文本框中的数据填充它。当我运行应用程序时,我只能看到报表上的列标题,而则不会在报表查看器上显示任何数据。
我的代码
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();
}
