水晶报告显示＆＃34;请等待文档处理＆＃34;

Question

我正在使用C＃处理Windows窗体应用程序，当我想在Crystal Report上打印Salary Slip时。它显示＆＃34;请等待文档正在处理＆＃34;对话框及其继续处理并挂起我的应用程序。其余所有Crystal Reports Working Fine接受此单一报告。 请指导我什么是问题

这是我的代码

string qry = @"SELECT (Select emp_name from employ_tbl where emp_id=SM.emp_id) AS emp_id,Salary,Adv_deduction,Mdcn_deduction,Loan_deduction,Oth_deduction,Total_Absents,'' AS AbsentAmount,SM.Current_Salary,(select sum(amount) from salarybonus where bonusMounth='"
            + month + @"' AND emp_id=SM.emp_id AND name IS NOT NULL ) AS b_amount FROM SalaryManagement_tbl SM WHERE SM.Month='" + month + "' AND SM.emp_id=6";

string connection = cm.constring();
        SqlConnection con = new SqlConnection(connection);
        ReportDocument cryRpt = new ReportDocument();


 DataTable ds = new DataTable();
        con.Open();
        SqlDataAdapter adp = new SqlDataAdapter(qry, con);
        adp.Fill(ds);
        con.Close();
        cryRpt.Load(@"fullpath\PaySlip.rpt");
        cryRpt.SetDataSource(ds);
        crystalReportViewer1.ReportSource = cryRpt;
