打印预览而不将文件保存为pdf [英] Print preview without saving the file into pdf

问题描述

我创建了一个Windows窗体的水晶报表和一个Crystalreportviewer.以下是我的代码.

Hi,

I''ve created one crystal report in windows form and one crystalreportviewer. The following is my code.

//in form1.cs file
try
{
ExportOptions CrExportOptions;
DiskFileDestinationOptions CrDiskFileDestinationOptions = new DiskFileDestinationOptions();
PdfRtfWordFormatOptions CrFormatTypeOptions = new PdfRtfWordFormatOptions();
CrDiskFileDestinationOptions.DiskFileName = "c:\\csharp.net-informations.pdf";
CrExportOptions = cryRpt.ExportOptions;
{
 CrExportOptions.ExportDestinationType = ExportDestinationType.DiskFile;
 CrExportOptions.ExportFormatType = ExportFormatType.PortableDocFormat;
 CrExportOptions.DestinationOptions = CrDiskFileDestinationOptions;
 CrExportOptions.FormatOptions = CrFormatTypeOptions;
}
 cryRpt.Export();
}

上面的代码将文件保存为pdf到指定的路径.我不想保存文件，我应该直接进行打印预览并可以选择打印.

就像我们在使用Crystal Report Viewer的Web应用程序中所做的一样，单击打印"，然后将以pdf格式打开报告，然后单击打印".

我想要与我们在Web应用程序中相同的功能.我正在C#.Net中编写代码

希望上面的解释能清楚理解.

Above code is saving the file into pdf into specified path. I dont want to save a file I should get direct print preview and have a option to print.

As we do in web application using crystal report viewer clicking print and report will be opened in pdf and the click print.

I want the same function as we do in web application. I am writing code in C#.Net

Hope the above explaination will be understood clearly.

推荐答案

您可以在ASP.Net中以这种方式将Crystal报表导出到内存pdf:

You can export a crystal report to a memory pdf this way in ASP.Net:

MemoryStream oStream; // using System.IO
oStream = (MemoryStream)
report.ExportToStream(
CrystalDecisions.Shared.ExportFormatType.PortableDocFormat);
Response.Clear();
Response.Buffer= true;
Response.ContentType = "application/pdf";
Response.BinaryWrite(oStream.ToArray());
Response.End();

如果使用Windows窗体，则需要使用Crystal Report Viewer控件.这是有关如何使用该控件的教程:

If you are using windows forms, you need to use the crystal report viewer control. Here is a tutorial on how to use that control:
