　　报表是每个做信息系统产品人员都应该关注的一部分，在WPF下很多人使用FlowDocuments来生成报表，这个虽然不错，但是对于复杂的报表来说还是需要一个报表引擎。

Open-Source .NET WPF Reporting Engine

　“This project allows you to create reports using WPF (WindowsPresentation Foundation). Its supports headers and footers, DataTablebinding, barcode generation, XPS creation and more.”

　　它是现在WPF版本下的一个报表引擎，目前版本还比较低（v0.5 alpha），但是可以作为以后OpenExpressAppWPF版本报表的预览控件的参考。

　　下面放上几张它例子的图，感兴趣的也可以去看看。







使用

Open-Source WPF Reporting Engine

FlowDocuments

　　最开始说过有人使用FlowDocuments来做报表，以下为一个例子，想使用这个来作报表的可以参考。

First things, first… Create a ReportDocument. This is the “container" for our report

view sourceprint?

1
ReportDocument reportDocument =
new
ReportDocument();
Next, we need to supply a template for our report.

view sourceprint?

1
StreamReader reader =
new
StreamReader(
new
FileStream(
@"Templates\SimpleReport.xaml"
, FileMode.Open, FileAccess.Read));
2
reportDocument.XamlData = reader.ReadToEnd();
3
reportDocument.XamlImagePath = Path.Combine(Environment.CurrentDirectory,
@"Templates\"
);
4
reader.Close();
Here is how our template looks

I will go into more detail on how to customize this template in future posts. Now the data…

view sourceprint?

1
ReportData data =
new
 
ReportData();
First add some “metadata”

view sourceprint?

1
data.ReportDocumentValues.Add(
"PrintDate"
, DateTime.Now);
And then the DataTables

view sourceprint?

1
data.DataTables.Add(table);
Here, table is of type DataTable.

And that is it!

Finally export it to Xps and show

view sourceprint?

1
XpsDocument xps = reportDocument.CreateXpsDocument(<strong>data</strong>);
You can use the standard DocumentViewer to display the report
