reportviewer 开发报表 笔记

简单的reportViewer开发 是由三个部分组成
1: 数据源
2:页面模板层次
3:asp显示嵌入

1:固定模板开发（列不会变化）
可以用visual studio
-->new 一个.xsd 里面放置数据源 其实很像一个视图
                        你查询数据填充进去
-->new 一个.rdlc
                把数据源和.xsd 绑定 显示在对应的位置 并作一些显示行列调整
          注：其中rdlc里面的函数 是以vb的语法为基础的 eg:iff..
                   可以用它作一些页面数据显示的操作 eg:日期转换，数据为空处理
                   footer里面做求和...什么的
-->new 一个asp  把对应的ReportViewer 嵌套进去

 <rsweb:ReportViewer ID="ProjectTestAssessByUserRV" runat="server" Width="100%" Height="100%" 
                        ShowPrintButton="False" ShowRefreshButton="False" ShowFindControls="False" 
                        BackColor="#DBE6F0" BorderColor="#BBBCB1" BorderWidth="1px" 
                        Font-Names="Verdana" Font-Size="8pt">
                        <LocalReport ReportPath="你命名的.rdlc">                          
                        </LocalReport>                                          
                    </rsweb:ReportViewer>

在.aspx.cs中

       DataTable dt = new DataTable(); 你取得的数据 //注意列名和数据源里面一样
                ReportDataSource ds = new ReportDataSource("数据源名称", dt);
                ProjectTestAssessByBmRV.LocalReport.DataSources.Clear();
                ProjectTestAssessByBmRV.LocalReport.DataSources.Add(ds);
                ProjectTestAssessByBmRV.LocalReport.DisplayName = "报表名称";
                ProjectTestAssessByBmRV.LocalReport.EnableHyperlinks = true;
                ProjectTestAssessByBmRV.HyperlinkTarget = "_blank";

这样一个简单的报表就形成了 很简单 而且 reportviewer提供导出 打印等功能 你自己添加对应的属性 就OK了

2：列不固定 的动态报表
  此时 你没法预定义数据源 和.rdlc
这样就必须你自己手动的创建了
  实验了下

这两个类的作用 就是动态生成rdlc并绑定数据源的核心代码 相信看的懂java和c#的都可以明白
再我们在asp里面还是一样加一个reportviewer
核心代码

//显示页面 在pageLoad可以调用它 传入你对应的数据
 private void ShowReport(DataTable dt)
        {
            this.rv.Reset();
            this.rv.LocalReport.LoadReportDefinition(memoryStream);
            this.Prv.LocalReport.DataSources.Add(new ReportDataSource("ReportData", dt));
            rv.LocalReport.Refresh();
            rv.LocalReport.EnableHyperlinks = true;
            rv.HyperlinkTarget = "_blank";
            rv.LocalReport.DisplayName = "test";
        }

        //生成rdlc
        private MemoryStream GenerateRdl(List<string> allFields, List<string> selectedFields, string url)
        {
            MemoryStream ms = new MemoryStream();
            RdlGenerator gen = new RdlGenerator();

            gen.Url = "";
            gen.AllFields = allFields;
            gen.SelectedFields = selectedFields;
            gen.WriteXml(ms);
            ms.Position = 0;
            return ms;
        }

只要你有心拼凑 肯定可以做出一个动态的报表

因为我搞.net只是随意学习 (一直作java方面开发)  所以很多东西只是作个代码的展示 但是我想 要是有人做这方面的东西 还是有点用的 嘿嘿
