如何在不询问参数字段的情况下在Asp.Net C＃中的Crystal Report中加载子报表

Question

I am developing software in asp.net c#, in that it have a Crystal Reports & also Crystal Reports has a sub report in it..

I load only main report through pass the value of bolReports.Year,

The problem is: I can't load sub report using the same parameter..

When I run the page means it ask parameter to sub reports..

Anyone help, thanks in advance..

DataSet ds = new DataSet("tbl");
ReportDocument cryRptDoc = new ReportDocument();
string ReportPath = string.Empty;

bolReports.Year = ddlYear.SelectedValue.Trim();

ReportPath = Server.MapPath("~\\Reports\\PerCallBrnMon.rpt");
cryRptDoc.Load(ReportPath);
cryRptDoc.SetDatabaseLogon(bolReports.UserID, bolReports.Password, bolReports.ServerName, bolReports.DataBaseName);
ds = bolReports.sp_CallClosing();
cryRptDoc.SetDataSource(ds.Tables[0]);

CrystalReportViewer1.ReportSource = cryRptDoc;
CrystalReportViewer1.DataBind();

CrystalReportViewer1.ToolPanelView = CrystalDecisions.Web.ToolPanelViewType.None;
CrystalReportViewer1.HasExportButton = false;
CrystalReportViewer1.HasPrintButton = false;
CrystalReportViewer1.Zoom(80);

Main Report Name : PerCallBrnMon.rpt

Sub Report Name : PerCallBrnMonGrp.rpt

In this code, I have run only main report & main report stored procedure, & I don't know how to run sub report & sub report stored procedure.. the main report has a sub report in it, & both having the same parameter of bolReports.Year ..

In the template add the links between the main report and the subreport. It should be available in one of the options in the context menu of the subreport.
