Export to Pdf: PdfFormatProvider not working

[ajin prasad]

Hi All,

I am using PdfFormatProvider to export PDF document. It throws the error "Index was outside the bounds of the array." in the line provider2.Export(bigbook, output); 

The same code works fine with 
XamlFormatProvider
TxtFormatProvider
HtmlFormatProvider

please see the below code for implementation

  void ExportPDF2_Click(object sender, RoutedEventArgs e)
        {
           this.Cursor = Cursors.Wait;

          

            RadDocument theContent = LoadContent();

            RadDocument bigbook = new RadDocument();
            Section section1 = new Section();
            Paragraph paragraph1 = new Paragraph();

            Span span1 = new Span(TVM.TOC3);
            paragraph1.Inlines.Add(span1);
            section1.Blocks.Add(paragraph1);
            bigbook.Sections.Add(section1);

            
            foreach (Section section in theContent.Sections)
            {
                Section copySection = section.CreateDeepCopy() as Section;
                theContent.Sections.Remove(section);
                bigbook.Sections.Add(copySection);
            }

            this.Cursor = Cursors.Arrow;

            //-----------------------------------------------

            PdfFormatProvider provider2 = new PdfFormatProvider();
           
        
            

            SaveFileDialog saveDialog = new SaveFileDialog();
            saveDialog.DefaultExt = ".pdf";
            saveDialog.Filter = "PDF Document|*.pdf";
            bool? dialogResult = saveDialog.ShowDialog();
            if (dialogResult == true)
            {
                using (System.IO.Stream output = saveDialog.OpenFile())
                {
                    

                    provider2.Export(bigbook, output); //Error at this line
                    MessageBox.Show("Saved Successfully!");
                }
            }
        }

This code works fine with XamlFormatProvider, TxtFormatProvider, HtmlFormatProvider. Issue is only with PDFFormatProvider

Can anyone help me in this?

[Vishal]

public static bool ConvertXamlToPDF(RadDocument document, string pdfPath)
        {
            Log.Info(System.Reflection.MethodBase.GetCurrentMethod().Name + " entering.");
            try
            {
                PdfFormatProvider provider = new PdfFormatProvider();
                var bytes = provider.Export(document);//Same Exception of "Index was outside the bounds of the array."

                if (File.Exists(pdfPath))
                {
                    File.SetAttributes(pdfPath, FileAttributes.Normal);
                }

                var fs = new FileStream(pdfPath, FileMode.Create);
                fs.Write(bytes, 0, bytes.Length);
                fs.Close();
            }
            catch (Exception ex)
            {
                Log.Error(System.Reflection.MethodBase.GetCurrentMethod().Name + " leaving with exception : " + ex.Message);
                return (false);
            }
            Log.Info(System.Reflection.MethodBase.GetCurrentMethod().Name + " leaving.");
            return (true);
        }

Hello,

Thank you for contacting us!

I tried replicating the issue you are observing, but to no avail. Could you please additional details about your setup and the content of the document you are loading? Also, please verify that you are using 2013.2 724 version of RadControls for Silverlight and all required assembly references are added to your project.

Generally, I'd like to point out that it is not recommended to use the CreateDeepCopy() method of document elements and the current approach you are using to merge documents might not always produce the expected result. Instead, I'd suggest you use the InsertFragment() method of RadDocumentEditor. You can revise the code of your application like this:

this.Cursor = Cursors.Wait;

RadDocument theContent = LoadContent();

RadDocument bigbook = new RadDocument()
    {
        LayoutMode = DocumentLayoutMode.Paged
    };
RadDocumentEditor documentEditor = new RadDocumentEditor(bigbook);

documentEditor.Insert(TVM.TOC3);

documentEditor.InsertSectionBreak();
documentEditor.InsertFragment(new DocumentFragment(theContent));

this.Cursor = Cursors.Arrow;

Additionally, please note that in Silverlight SaveFileDialog can only be shown if user-initiated. With your current setup if the loading of the document in the LoadContent() method or the logic executed after that takes longer time a security exception might occur. That said, I'd suggest initializing the dialog first and executing the other logic after that.

I hope these tips are helpful! If you are still experiencing problems please get back to us with additional details about your setup and the document you are trying to export. We would appreciate if you can provide us with such document exported to XAML format, so that we can troubleshoot the issue on our end.

I'm looking forward to your reply.

Hi.

Fixed the issue as per your suggestion. the following line helped to resolve the issue

documentEditor.InsertSectionBreak();

documentEditor.InsertFragment(new DocumentFragment(theContent));

Thanks for the help

[Vishal]

When this fix will be available?
Is it available for WPF also?

Hello,

@ajin prasad I am glad to hear the issue was resolved. Do not hesitate to get back to us if you have other questions or comments.

@Vishal We are unaware of any issues in PdfFormaProvider. The problem ajin prasad was experiencing is most likely related to the way the document was created rather that the export itself.

That said we would appreciate if you open a support ticket and send us a runnable example demonstrating the issue you are observing.

We are looking forward to hearing from you.
