[水晶报表]水晶报表创建以及调用方法

ASP.NET2.0/3.5/4.0水晶报表创建以及调用方法
1. 创建CrystalReport(网站中添加新项CrystalReport,或者单独开发水晶报表)放到指定目录
2、使用向导创建报表（如何创建请参考其它资料）Suppliers.rpt
3、VS.NET2005/2008/2010布局报表，添加删除字段.
4、回到页面,选择控件CrystalReportViewer将其放到页面上。
5、设置CrystalReportViewer1数据源（介绍两种方法）。

引入

using CrystalDecisions.Shared;using CrystalDecisions.CrystalReports.Engine;using CrystalDecisions.ReportSource;

第一种: 拉模式

    <CR:CrystalReportViewer ID="CrystalReportViewer1" runat="server"             AutoDataBind="True" GroupTreeImagesFolderUrl="" Height="1202px"          ReportSourceID="CrystalReportSource1" ToolbarImagesFolderUrl=""          ToolPanelWidth="200px" Width="1104px"   ToolPanelView="None" />     <CR:CrystalReportSource ID="CrystalReportSource1" runat="server">         <Report FileName="..\..\ERP\Reports\ZMQuotation.rpt">         </Report>     </CR:CrystalReportSource>

CS:

      CrystalReportSource1.ReportDocument.SetDatabaseLogon(PublicVar.ShatdbID, PublicVar.shatdbPW, PublicVar.ShatdbDS, PublicVar.Shatdb);//取得公共变量      CrystalReportSource1.ReportDocument.SetParameterValue("@ItemP", "no");      CrystalReportSource1.ReportDocument.SetParameterValue("@descriptionP", "no");      CrystalReportViewer1.DataBind();

     注释:PublicVar.ShatdbID 用户名, PublicVar.shatdbPW 密码, PublicVar.ShatdbDS 数据源(机器名或者IP), PublicVar.Shatdb 数据库名
          CrystalReportSource1.ReportDocument.SetParameterValue("@ItemP", "no"); 报表参数
     这种方法通常第一次登陆的时候就需要给定一个默认参数(如果带参数)
第二种:推模式

        string DBConfig_sql = PublicVar.strCon;        DataSet ds = new DataSet();        SqlConnection sqlCon = new SqlConnection(DBConfig_sql);        SqlCommand sqlCmd = new SqlCommand(sql, sqlCon);        SqlDataAdapter sqlAd = new SqlDataAdapter();        sqlAd.SelectCommand = sqlCmd;        sqlAd.Fill(ds, "sql");        //如果绑定报表        //注意此处必需指明Dataset中的表的名称，否则会提示“您请求的报表需要更多信息.”        CrystalReportSource1.ReportDocument.SetDataSource(ds.Tables["sql"]);        CrystalReportViewer1.ReportSource = CrystalReportSource1;        CrystalReportViewer1.DataBind();        //未绑定        String path = Server.MapPath("HandQty.rpt");        CrystalReportViewer1.Load(path);        CrystalReportSource1.ReportDocument.SetDataSource(ds.Tables["sql"]);        CrystalReportViewer1.ReportSource = CrystalReportSource1;        CrystalReportViewer1.DataBind();

存储过程：

        ReportDocument myReport = new ReportDocument();        SqlParameter[] parms = new SqlParameter[1];        parms[0] = new SqlParameter("@id", SqlDbType.Int);        parms[0].Value = id;         DataSet ds = new DataSet();        ds = DataAccess.DataAccessSHDB.GetTableByStore("project", parms).DataSet;         CrystalDecisions.CrystalReports.Engine.ReportDocument doc = new CrystalDecisions.CrystalReports.Engine.ReportDocument();        string reportPath = Server.MapPath("..//Reports//project.rpt");        //doc.Load(@"C:/test/1.rpt");        doc.Load(reportPath);        doc.SetDataSource(ds.Tables[0]);        CrystalReportViewer1.ReportSource = doc;        CrystalReportViewer1.DataBind();

如果有时候无法刷新数据：添加如下代码即可

      CrystalReportSource1.ReportDocument.SetParameterValue("@ItemP", "no");      CrystalReportSource1.ReportDocument.SetParameterValue("@descriptionP", "no");      CrystalReportViewer1.DataBind();

第三种方式：

直接show在页面，不含水晶报表工具栏；

private void Print()    {        SampleRequest sr = new SampleRequest();        sr.TaskCode = taskcode;        DataSet ds = new DataSet();        ds = sr.SampleRequestDetail();        if (ds != null)        {            CrystalDecisions.CrystalReports.Engine.ReportDocument doc = new CrystalDecisions.CrystalReports.Engine.ReportDocument();            string reportPath = Server.MapPath("..\\..\\ERP\\Reports\\SampleRequest.rpt");            doc.Load(reportPath);            doc.SetDataSource(ds.Tables[0]);            CrystalReportViewer1.ReportSource = doc;            CrystalReportViewer1.DataBind();            string filetype = "";            filetype = "PDF";            string contenttype = "";            //string myfilename = Request.MapPath(".\\") + Session.SessionID + "." + filetype;//目录地址 注意反义字符            string myfilename = "E:\\Report\\SAL\\" + "SampleRequest" + Baseclass.getLongData().ToString() + "." + filetype;            CrystalDecisions.Shared.DiskFileDestinationOptions mydiskoptions = new CrystalDecisions.Shared.DiskFileDestinationOptions();            mydiskoptions.DiskFileName = myfilename;            CrystalDecisions.Shared.ExportOptions myExportOptions = new ExportOptions();//oCR.ExportOptions;             myExportOptions.DestinationOptions = mydiskoptions;            myExportOptions.ExportDestinationType = CrystalDecisions.Shared.ExportDestinationType.DiskFile;            contenttype = "application/pdf";            myExportOptions.ExportFormatType = CrystalDecisions.Shared.ExportFormatType.PortableDocFormat;            doc.Export(myExportOptions); //输出报表 到服务器端的制定路径             Response.ClearContent();     //清空页面             Response.ClearHeaders();            Response.ContentType = contenttype;            Response.WriteFile(myfilename);//直接写入页面,页面平铺 可实现在线阅读功能            Response.Flush();            Response.Close();        }        else        {            JScript.Alert("没有找到记录", this.Page);        }    }
