[英]Pass parameter to a stored procedure to crystal report?
我開始閱讀本教程以利用水晶報表
http://www.codeproject.com/Articles/142064/Step-by-Step-Creation-of-Crystal-Report-using-its
我面對這種情況,在存儲過程中,我必須設置一些參數來獲取查詢。 因此,我以為我需要在運行時設置dataSource,但是我不知道如何將存儲過程結果發送到Crystal報表並在運行時顯示它(因為直到我知道,如果要在其中顯示某些內容,導入它,然后選擇要放置它的字段。
首先為Crystal Viewre創建新表格。在其中添加Crystal Viewer。
以這種形式添加此代碼
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();
}
using System;
using System.Collections.Generic;
using System.Data;
using System.Net;
using System.Text;
using CrystalDecisions.Web;
using CrystalDecisions.CrystalReports.Engine;
using CrystalDecisions.Shared;
namespace TexERP.ReportCrystal
{
public partial class AccountRegister : System.Web.UI.Page
{
clsSession objSession;
ReportDocument rptDoc;
protected void Page_Load(object sender, EventArgs e)
{
objSession = new clsSession();
rptDoc = new ReportDocument();
if (Session["objSession"] != null)
{
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();
}
}
}
你可以這樣
