报告生成器FastReport .NET实践指南：如何创建WebReport.Report中的ExportParameters事件

报表生成器FastReport .NET是适用于.NET Core 3，ASP.NET，MVC和Windows窗体的全功能报告库。使用FastReport .NET，您可以创建独立于应用程序的.NET报告。

近日，FastReport .Net升级到v2020.4版，在此版本中，添加了新的条形码：ITF-14和Deutsce Post Identcode，同时优化了多种性能（点击下方按钮下载），感兴趣的朋友可点击下方按钮下载最新版。

在FastReport 2020.1中，我们添加了更改导出参数的功能。因此，您必须在WebReport.Report中预订ExportParameters事件。

到目前为止，FastReport.Net库尚未提供对导出参数的访问。或更确切地说，它确实可以，但是仅对某些参数有效，并且借助于Web报表的各个属性。所有这些属性都是堆积在一起的，并且使用intelisense进行操作非常不方便，并且不能满足用户的所有需求。因此，决定使用特殊的ExportParameters事件为用户提供对导出对象的所有属性的访问权限。在事件处理程序中，您可以获取导出对象并设置所需的所有属性。因此，由于先前不可用的属性，现在可以更精确地配置导出。这是使用新事件的方法：

WebReport.Report.ExportParameters += (sender, e) =>
 {
 PDFExport export = e.Export as PDFExport;
 if (export != null)
 {
 export.Title = "test";
 export.DefaultPage = 2;
 }
 };
