RDLC（Reportview）报表直接打印，支持所有浏览器，客户可在linux下浏览使用

最近在做一个打印清单的，但是rdlc报表自带的工具栏中的打印按钮只有在ie内核下的浏览器才可以使用（其他的就会 隐藏），这导致了使用火狐和谷歌浏览器还有使用linux系统的客户打印成了问题，于是就自己百度搜，谷歌搜，然后就解决了，下面放上源码

打印类 PrintHelp（我需要两个table座位数据源所以参数中有两个datatable）

调用很简单 直接一句话

            new PrintHelp().Run(AppDomain.CurrentDomain.BaseDirectory + "\\Reports\\Report.rdlc", this.TextBox1.Text.Trim(), stationapplication.dthead, "headsource", stationapplication.dtmessage, "datasource", true);

 

由于原来的工具栏没了打印按钮 所以也就没有存在的必要了  隐藏掉 自己做一个工具栏出来

缩放、上一页下一页首页什么的
