水晶报表填充.Net Objects数据源

2014-04-23 23:37 375 查看
CrystalReports（水晶报表）是一款商务智能（BI）软件，主要用于设计及产生报表。是业内最专业、功能最强的报表系统。

查看网络资料及课本图书，鲜有介绍通过.NETObjects作为数据源填充水晶报表的示例。本文将通过两个简单的示例演示水晶报表填充.NetObjects数据源的过程。

示例一：打印学生信息（一个.NETObjects数据源的填充）

示例效果：





Student.cs

usingSystem;


usingSystem.Collections.Generic;


usingSystem.Web;




namespaceCrystalReportsDemo


{


publicclassStudent


{


publicStudent(stringstudentNo,stringstudentName,stringsex,intage)


{


this.StudentNo=studentNo;


this.StudentName=studentName;


this.Sex=sex;


this.Age=age;


}


publicstringStudentNo


{set;get;}


publicstringStudentName


{set;get;}


publicstringSex


{get;privateset;}


publicintAge


{get;privateset;}


}


}


将其编译后，即可通过数据库专家将其作为数据源导入到字段资源管理器。





绘制报表样式并插入数据库字段：





在Default.aspx页面拖入CrystalReportViewer控件：

<%@PageLanguage="C#"AutoEventWireup="true"CodeBehind="Default.aspx.cs"Inherits="CrystalReportsDemo._Default"%>




<%@Registerassembly="CrystalDecisions.Web,Version=13.0.2000.0,Culture=neutral,PublicKeyToken=692fbea5521e1304"namespace="CrystalDecisions.Web"tagprefix="CR"%>




<!DOCTYPEhtmlPUBLIC"-//W3C//DTDXHTML1.0Transitional//EN""http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">




<htmlxmlns="http://www.w3.org/1999/xhtml">


<headrunat="server">


<title></title>


</head>


<body>


<formid="form1"runat="server">


<div>




<CR:CrystalReportViewerID="crvReport"runat="server"AutoDataBind="true"/>




</div>


</form>


</body>


</html>


Default.aspx.cs

usingSystem;


usingSystem.Collections.Generic;


usingSystem.Web;


usingSystem.Web.UI;


usingSystem.Web.UI.WebControls;




namespaceCrystalReportsDemo


{


publicpartialclass_Default:System.Web.UI.Page


{


protectedvoidPage_Load(objectsender,EventArgse)


{


FillReport();


}


privatevoidFillReport()


{


List<Student>studentList=newList<Student>();


studentList.Add(newStudent("200901001","学生一","男",23));


studentList.Add(newStudent("200901002","学生二","男",24));


studentList.Add(newStudent("200901003","学生三","女",22));


studentList.Add(newStudent("200901004","学生四","男",23));


studentList.Add(newStudent("200901005","学生五","女",25));


studentList.Add(newStudent("200901006","学生六","男",23));


CrStudentsstudentsReport=newCrStudents();


studentsReport.SetDataSource(studentList);


crvReport.ReportSource=studentsReport;


}


}


}


示例二：打印学生成绩（多个.NETObjects数据源的填充）

示例效果：





Subject.cs

usingSystem;


usingSystem.Collections.Generic;


usingSystem.Web;




namespaceCrystalReportsDemo


{


publicclassSubject


{


publicSubject(stringsubjectName,stringsubjectType,doubleresult,stringcomment)


{


this.SubjectName=subjectName;


this.SubjectType=subjectType;


this.Result=result;


this.Comment=comment;


}


publicstringSubjectName


{set;get;}


publicstringSubjectType


{set;get;}


publicdoubleResult


{set;get;}


publicstringComment


{set;get;}


}


}


主报表：（CrSupReport.rpt）





子报表：（CrSubReport.rpt）
