Question

我有一个RadGridView，应该导出为doc，pdf，csv和xls格式。导出到doc，csv和xls工作正常......但是将它导出为pdf格式有问题。导出到pdf有效，但我隐藏的列仍显示...

所以我只想通过以下方式将RadGridView导出为pdf：将其导出为word然后以编程方式将其转换为pdf ...

顺便说一下，这是我导出为单词的代码。

//export to doc
private void Export_Doc(object sender, System.Windows.RoutedEventArgs e)
{
    ExportDialog("doc", "Word", ExportFormat.Html);
}
private void ExportDialog(string extension, string selectedItem, ExportFormat format)
{
    SaveFileDialog dialog = new SaveFileDialog();
    dialog.DefaultExt = extension;
    dialog.Filter = String.Format("{1} files (*.{0})|*.{0}|All files (*.*)|*.*", extension, selectedItem);
    dialog.FilterIndex = 1;
    if (dialog.ShowDialog() == true)
    {
        using (Stream stream = dialog.OpenFile())
        {
            GridViewExportOptions exportOptions = new GridViewExportOptions();
            exportOptions.Format = format;
            exportOptions.ShowColumnFooters = true;
            exportOptions.ShowColumnHeaders = true;
            exportOptions.ShowGroupFooters = true;

            RadGridView1.Export(stream, exportOptions);
        }
    }
}

通过OLE自动化使用word（注意：单词COM不可重入 - 确保不要从不同的线程同时调用它）：

    /// <summary>
    /// Interacts directly with Word via COM to convert a document to PDF
    /// Must have the Microsoft enhancement installed to support Save As PDF
    /// in the word file menu
    /// "2007 Microsoft Office Add-in: Microsoft Save as PDF or XPS" - SaveAsPDFandXPS.exe
    /// </summary>
    private void ExportToPDFUsingWord(object sourceDoc, string destPDF)
    {
        object m = System.Reflection.Missing.Value;
        object readOnly = true;
        object myFalse = false;
        object isVisible = false;
        object matchCase = false;
        object matchWholeWord = true;
        object saveChangesWhenQuitting = false;

        //Debug("Connecting to word");
        _Application oWordApp = new Application();
        _Document oWordDoc = null;
        Documents oWordDocs = null;

        try
        {
            // load the source file
            //Debug("Opening " + sourceDoc);
            oWordDocs = oWordApp.Documents;
            oWordDoc = oWordDocs.Open(ref sourceDoc, ref m, ref readOnly, ref m, ref m, ref m, ref m, ref m, ref m, ref m, ref m, ref isVisible, ref m, ref m, ref m, ref m);

            if (oWordDoc != null)
            {
                try
                {
                    WdExportFormat paramExportFormat = WdExportFormat.wdExportFormatPDF;

                    bool paramKeepIRM = true;
                    WdExportCreateBookmarks paramCreateBookmarks = WdExportCreateBookmarks.wdExportCreateWordBookmarks;
                    bool paramDocStructureTags = true;
                    bool paramBitmapMissingFonts = true;
                    bool paramUseISO19005_1 = false;

                    // 
                    // Export the file to PDF. 
                    //Debug("Exporting to " + destPDF); 
                    oWordDoc.ExportAsFixedFormat(destPDF,
                        paramExportFormat, paramOpenAfterExport,
                        paramExportOptimizeFor, paramExportRange, paramStartPage,
                        paramEndPage, paramExportItem, paramIncludeDocProps,
                        paramKeepIRM, paramCreateBookmarks, paramDocStructureTags,
                        paramBitmapMissingFonts, paramUseISO19005_1,
                        ref m);
                }
                finally
                {
                    //Debug("Closing " + sourceDoc); 
                    oWordDoc.Close(ref saveChangesWhenQuitting, ref m, ref m);
                }
            }
            else
                throw new FileLoadException("Documents.Open returned null for file \'" + sourceDoc + "\', perhaps use comexp.msc and change DCOM->Word97-2003 Identity to Interactive user");  // if you are running from within a service then Word behaves differently - it is designed as a user application which must have a user interface
        }
        finally
        {
            // close word and cleanup

            //Debug("Collecting garbage");
            GC.Collect();  // forces the garbage collector to run and might release any references that the RCW still has
            GC.WaitForPendingFinalizers();
            //Debug("Word objects finished");
        }
    }

使用DevExpress（以下代码仅适用于RTF格式 - 不一定适用于所有Word的功能）：

private void ExportToPDFUsingDevExpress(string sourceDoc, string destPDF)
    {
        DevExpress.XtraPrinting.PrintingSystem printingSystem1 = new DevExpress.XtraPrinting.PrintingSystem();
        DevExpress.XtraRichEdit.RichEditControl richEditControl1 = new DevExpress.XtraRichEdit.RichEditControl();
        richEditControl1.LoadDocument(sourceDoc);
        DevExpress.XtraPrinting.PrintableComponentLink link = new DevExpress.XtraPrinting.PrintableComponentLink(printingSystem1);
        link.Component = richEditControl1;
        link.CreateDocument();
        link.PrintingSystem.ExportToPdf(destPDF);
    }
