asp.net打印(谁有更好的办法)
因为要做打印页面一部分,但是一直没有找到好的解决方案,请下面是一个WEB中打印datagrig数据的方法
如果谁有打印datagrid中嵌套datalist打印方法,请偷偷的告诉我一下:)

另外,还可以把dataset的数据导入到水晶报表,然后再倒入pdf,doc,xsl,html等中进行打印,下面是方法
CrystalReport1 myreport = new CrystalReport1();
SqlDataProvider sqldataprovider =new SqlDataProvider();
myreport.SetDataSource(sqldataprovider.RunProcDataSet("Show_authors").Tables[0]);//sqldataprovider.RunProcDataSet("Show_authors").Tables[0]是datatable
CrystalDecisions.Shared.DiskFileDestinationOptions DiskOpts =new DiskFileDestinationOptions();
myreport.ExportOptions.ExportDestinationType =CrystalDecisions.Shared.ExportDestinationType.DiskFile;
//myreport.ExportOptions.ExportFormatType=CrystalDecisions.Shared.ExportFormatType.PortableDocFormat;//这里是pdf
myreport.ExportOptions.ExportFormatType=CrystalDecisions.Shared.ExportFormatType.WordForWindows;//这里是word
DiskOpts.DiskFileName = "c:\\Output.doc";
myreport.ExportOptions.DestinationOptions = DiskOpts;
myreport.SetDatabaseLogon("sa", "hyaocuk!", "127.0.0.1", "pubs");
myreport.Export();
