I'm facing this situation, in a stored procedure I have to set some parameters to get the query. So I supposed I need to set the dataSource in runtime, but I have no idea about how to send the stored procedure result to crystal reports and show it in runtime (because until I know, if you want to display something in it, you have to import it and select the fields that you want to place it.

我面对这种情况，在一个存储过程中，我必须设置一些参数来获取查询。所以我认为我在运行时需要设置数据源,但我不知道如何发送水晶报表的存储过程结果并显示它在运行时(因为,直到我知道,如果你想要显示的东西,你必须导入它并选择您想要将它的字段。

            pstrType = Request.QueryString["Type"];
            DataSet dsData = null;

            dsData = objAccountReportBAL.getAccountRegister(Convert.ToInt16(objSession.FyId), int.MinValue, long.MinValue, Convert.ToDateTime(RadDtpFromDate.SelectedDate), Convert.ToDateTime(RadDtpToDate.SelectedDate), pstrType);          
            rptDoc.Load(Server.MapPath("~/ReportCrystal/Account/Detail/GeneralVoucharRegister.rpt"));          
            rptDoc.SetDataSource(dsData.Tables[0]);

            Session["ReportDataSet"] = rptDoc;
            crvAccountReportParameter.ReportSource = rptDoc;
            crvAccountReportParameter.DataBind();          
        }
    }
}

You can do like this........

first make new form for crystal viewre.. add crystal viewer in it..

首先为水晶视图制作一个新表格。在里面添加水晶查看器

add this code in that form

以那种形式添加此代码

public void ShowForm(DataSet pDataSet)
    {
CrystalDecisions.Shared.ConnectionInfo ConnInfo = new CrystalDecisions.Shared.ConnectionInfo();
ReportDocument RepDoc = new ReportDocument();
RepDoc.Load(ReportPath With Rpt name);

TableLogOnInfo TableLogOnInfo;
        ConnInfo.ServerName = ServerName;
        ConnInfo.DatabaseName = ServerDBName;
        ConnInfo.UserID = ServerDBUserName;
        ConnInfo.Password = ServerDBPassWord;
        foreach (Table TableInRep in RepDoc.Database.Tables)
        {
            TableLogOnInfo = TableInRep.LogOnInfo;
            TableLogOnInfo.ConnectionInfo = ConnInfo;
            TableInRep.ApplyLogOnInfo(TableLogOnInfo);
        }
CryViewer.ReportSource = RepDoc;
RepDoc.Database.Tables[0].SetDataSource(pDataSet);

this.Show();

}

}
