Import DocIO Docx document into EJ2 DocumentEditor removes headers and footers

[Lion Tales]

I’m using C# to load a .docx file with Syncfusion DocIO, then convert it into the EJ2 DocumentEditor model via:

[HttpPost("Import")]

public IActionResult Import(IFormCollection data)

{

    if (data.Files.Count == 0)

        return BadRequest("No file uploaded.");

    using var ms = new MemoryStream();

    // data.Files[0] is a DocIo DocX document
    data.Files[0].CopyTo(ms);

    ms.Position = 0;

    var ext = Path.GetExtension(data.Files[0].FileName).ToLowerInvariant();

    var doc = WordDocument.Load(ms,

      ext switch

      {

          ".docx" => FormatType.Docx,

          ".doc" => FormatType.Doc,

          ".rtf" => FormatType.Rtf,

          ".txt" => FormatType.Txt,

          ".xml" => FormatType.WordML,

          _ => throw new NotSupportedException(ext)

      });

    var sfdt = JsonConvert.SerializeObject(doc);

    doc.Dispose();

    return Content(sfdt, "application/json");

}

After this, editorDoc.Sections[i].HeadersFooters.Header (and FirstPageHeader/EvenHeader) are always empty, even though docIo.Sections[i].HeadersFooters.Header contains my header content. I’d like to preserve and display all headers/footers in the EJ2 editor. What am I missing, or is there a different API I should call to carry over headers and footers?

If there isn't any other way, I even prepare to add these headers manually, but I don't know how to add them to the EJ2 object. I got as far as this code:

using var docIo = new Syncfusion.DocIO.DLS.WordDocument(ms, Syncfusion.DocIO.FormatType.Docx);

using var saveStream = new MemoryStream();

docIo.Save(saveStream, Syncfusion.DocIO.FormatType.Docx);

docIo.Close(); 

saveStream.Position = 0;

var editorDoc = Syncfusion.EJ2.DocumentEditor.WordDocument.Load(saveStream, FormatType.Docx);

// Iterate sections and grab the default header (or FirstPageHeader / EvenHeader etc.)

foreach (WSection section in docIo.Sections)

{

    var header = section.HeadersFooters.Header; // default/odd-page header

    var first = section.HeadersFooters.FirstPageHeader;

    var even = section.HeadersFooters.EvenHeader;

    foreach (var para in header.Paragraphs)

    {

    }

}

Thank you.

Our Document Editor supports the Header/Footer created from DocIo.     https://ej2.syncfusion.com/aspnetcore/documentation/document-editor/header-footer   Query:  editorDoc.Sections[i].HeadersFooters.Header (and FirstPageHeader/EvenHeader) are always empty.   Details: If the ‘Link to Previous’ option is enabled for the header/footer of the document,  ‘editorDoc.Sections[i].HeadersFooters.Header (and FirstPageHeader/EvenHeader)’ for some sections will be empty .   Also, we suspect that the reported problems are might be due to the contents in the input word document which used at your end. We need to investigate with the contents in your input Word document to reproduce the exact problem at our end. So, could you please provide us the input Word document which used at your end and also share the details of issue if you faced any in console, detailed replication procedure, video demonstration and code snippet. Thereby, we will analyse further and provide you the appropriate solution at the earliest.   Note: If you have any confidential data in your Word document, please replace with some dummy data and provide us the same. We just need your document to recreate the problem you face.

Hello,

Thank you for your reply. I attached in a zip file - 3 files - 

1. Test_With_Headers - The file with the headers before import
2. Test_Document_Editor_Saved - The file with the headers after import - no headers.
3. Document Editor Screenshot - picture of the document editor after import (no headers)

Thank you for your effort.

Hi Lion,

 

We have tried to reproduce the reported issue with opening the document using Import() API, but it works properly. We have shared the sample with the steps which we have tried to reproduce the issue.

 

Steps to run the sample.

1. Run the sample and 0pen ‘Test_With_Headers.docx’ document
2. Click on ‘SaveAsblob’ for client export
3. Click on ‘ServerExport’ to export the document in server side  

 

Please try it and revert with detailed replication steps, modified sample, video demonstrating the issue if you still have concerns. These details will be helpful for us to investigate further and assist you with prompt solution.

Akshaya

Thanks for the files, it is working in my side too.

But I was mistaken, the test file I sent before was saved in Word so it fixed the headers problems before the import.

I attached here another file, this one is not working even with your example.

Thanks.

Thank you for your support!

I want to add something that maybe is related and maybe not - if not, I can open a new post.

The display in the document editor and the docx is not the same in page by page. 

Not by a small change but in a lot of rows. I want to know if it's because of that merge problem between DocIO to Document editor.

I added here a zip file with the document and two pictures - Word Docx display and Document Editor display of the same document.

In addition I add the Import and Save functions for the server and client (same result):

Server Import:

[HttpPost("Import")]

public IActionResult Import(IFormCollection data)

{

    if (data.Files.Count == 0)

        return BadRequest("No file uploaded.");

    using var ms = new MemoryStream();

    data.Files[0].CopyTo(ms);

    ms.Position = 0;

    var sfDoc = new Syncfusion.DocIO.DLS.WordDocument(ms, Syncfusion.DocIO.FormatType.Docx);

    Syncfusion.EJ2.DocumentEditor.WordDocument document = Syncfusion.EJ2.DocumentEditor.WordDocument.Load(sfDoc);

    var sfdtJson = JsonConvert.SerializeObject(document);

    document.Dispose();

    return Content(sfdtJson, "application/json");

}

Server Save Word:

Syncfusion.DocIO.DLS.WordDocument wordDocument = new Syncfusion.DocIO.DLS.WordDocument(processedResult.FormattedStream, WFormatType.Docx);

MemoryStream stream = new MemoryStream();

wordDocument.Save(stream, Syncfusion.DocIO.FormatType.Docx);

wordDocument.Close();

Client Save Word:

//DocumentEditor editor

editor.save(`${this.file}.docx`, "Docx");

Hello,

Thank you for your efforts. It did fixed the problem! Now I can see the headers in the document editor and can save them.

I did find another issue, let me know if it's easy to solve - 

When I have sections in the word file, for different headers in different sections, the page numbering is not consistent with the Word document.

In Word Docx the page number is 7 (correct) but in the document editor is 2 (wrong).

I attached an example for you to check - if you will load it to the document editor you will get in the second section page 2, but in the Docx, the first number in the second section is 7.

Thank you.
