Question

我开始阅读本教程以利用水晶报告

http://www.codeproject.com/Articles/142064/Step-by-Step-Creation-of-Crystal-Report-using-its

我正面临这种情况，在存储过程中我必须设置一些参数来获取查询。所以我想我需要在运行时设置dataSource，但我不知道如何将存储过程结果发送到水晶报表并在运行时显示（因为直到我知道，如果你想在其中显示某些内容，你有导入它并选择要放置它的字段。

Answer 1

首先为水晶观察者制作新形式..在其中添加水晶观察器..

以该表格添加此代码

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();

}

                objSession = Session["objSession"] as clsSession;
            }

            if (!IsPostBack)
            {
                Session["ReportDataSet"] = null;
            }
            if (Session["ReportDataSet"] != null)
            {
                crvAccountReportParameter.ReportSource = (ReportDocument)Session["ReportDataSet"];
            }
        }


        protected void btnSubmit_Click(object sender, EventArgs e)
        {
            LoadData();         
        }
        protected void LoadData()
        {
            string pstrType;
            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();          
        }
    }
}

你可以这样做........

将参数传递给存储过程到晶体报告？
