wpf 基于模板的报表设计及打印预览
  wpf 中可以使用reportingservers ,水晶报表等东西,但是如果使用reportingservers 在频繁的数据交互中是 比较浪费资源或者存在效率问题。所以还有没有更好的办法呢。答案肯定是有的。
wpf中基于模板的报表设计就可以完成以上内容,对于要修改的报表文件是以文件的方式存放在服务器上,每次读取报表文件还是很方便的!
开工:第一步引入一个三方的dll ,这里集成了很多报表展示格式,有图文,有分组显示,具体源码我这里也有,需要的留言


第二部:创建你要做的报表文件:

    <FlowDocument xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                  xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

                </TableRowGroup>

            </Table>
         
        </Section>
    </FlowDocument>

里面的内容大家可以看下,wpf 中就要用table标签,如果用grid 展示的话,在xp 会不兼容!


以上就是报表文件了

第三步:在wpf 窗体中调用;

页面中加入documentViewer 控件,用来展示 报表

    ReportDocument reportDocument = new ReportDocument();
                    var path = AppDomain.CurrentDomain.SetupInformation.ApplicationBase;
                    StreamReader reader = new StreamReader(new FileStream(path + @"Template\Performance.Template.xaml", FileMode.Open, FileAccess.Read));   // 读取报表的模板文件

                    reportDocument.XamlData = GetContent(reader.ReadToEnd());  // 这里是替换模板文件中的 静态变量内容
                    reportDocument.XamlImagePath = Path.Combine(Environment.CurrentDirectory, @"Template\");//几乎用不到
                    reader.Close();
                    ReportData data = new ReportData();
                    var table = GetRoundScore();
                    data.DataTables.Add(table); //根据报表文件中的data数据 赋值
                    XpsDocument xps = reportDocument.CreateXpsDocument(data);
                    documentViewer.Document = xps.GetFixedDocumentSequence();   // 展示报表

复制代码
报表的预览完成了,你可以调用预览窗口中的 打印按钮打印。也可以自己 添加打印事件!内容如下:

    documentViewer.Document = null;
                PrintDialog pd = new PrintDialog();
                DataSet ds = CreateReportCondata(_billNo);
                if (ds.Tables[0].Rows.Count > 0)
                {
                    ReceiptPrint(ds.Tables[0], ds.Tables[1]);
                    PrintQueue pq = pd.PrintQueue;
                    //本机默认打印机打印
                    pq.ShareName = new LocalPrintServer().DefaultPrintQueue.ShareName;
                    var paginator = documentViewer.Document.DocumentPaginator;
                    pd.PrintDocument(paginator, " 打印");
                }

复制代码
以上如果不预览的话,直接可以new 这样的窗体,调用上面的方法可以直接打印
