如何限制水晶报表中的导出格式

Question

对于visual studio .net 2005的Crystal报表,您可以将报表导出为各种文件格式,如pdf,excel,word,rpt等.如果我只想限制用户只看excel和word格式并设置默认文件格式要超越,有办法吗？有时太多选择不好,是吗？

Answer 1

使用CRVS2010,您可以删除不需要的导出选项.

CRVS2010的一项新功能是能够从查看器导出按钮修改可用的导出格式.以下C#示例代码演示了如何将CrystalReportViewer设置为仅导出为PDF和Excel文件格式:

int exportFormatFlags = (int)(CrystalDecisions.Shared.ViewerExportFormats.PdfFormat | CrystalDecisions.Shared.ViewerExportFormats.ExcelFormat);
CrystalReportViewer1.AllowedExportFormats = exportFormatFlags;

您没有提及您使用的是 C# / VB.NET 还是 Web/WinForms。

C＃

我认为这是不可能的。您必须实现自己的导出按钮。

类似于这篇MSDN 文章的内容

C＃

// Declare variables and get the export options.
ExportOptions exportOpts = new ExportOptions();
ExcelFormatOptions excelFormatOpts = new ExcelFormatOptions ();
DiskFileDestinationOptions diskOpts = new DiskFileDestinationOptions();
exportOpts = Report.ExportOptions;

// Set the excel format options.
excelFormatOpts.ExcelUseConstantColumnWidth = true;
exportOpts.ExportFormatType = ExportFormatType.Excel;
exportOpts.FormatOptions = excelFormatOpts;

// Set the disk file options and export.
exportOpts.ExportDestinationType = ExportDestinationType.DiskFile;
diskOpts.DiskFileName = fileName;
exportOpts.DestinationOptions = diskOpts;

Report.Export ();

' Declare variables and get the export options.
Dim exportOpts As New ExportOptions()
Dim diskOpts As New DiskFileDestinationOptions()
Dim excelFormatOpts As New ExcelFormatOptions()
exportOpts = Report.ExportOptions

' Set the excel format options.
excelFormatOpts.ExcelTabHasColumnHeadings = true

exportOpts.ExportFormatType = ExportFormatType.Excel
exportOpts.FormatOptions = excelFormatOpts

' Set the export format.
exportOpts.ExportFormatType = ExportFormatType.Excel

exportOpts.ExportDestinationType = ExportDestinationType.DiskFile

' Set the disk file options.
diskOpts.DiskFileName = fileName
exportOpts.DestinationOptions = diskOpts

Report.Export()

您过去可以从客户端安装中删除某些导出 DLL。即删除除 Excel DLL 之外的所有内容，然后它只会将导出选项显示为 Excel
