XML Mappings lost when resaving file


I would like to use Aspose.Cells for one of my projects where I want to open XLSX file with XML mappings, change few cells and re-save the file.

When I try to do this with Aspose.Cells (opening existing file, changing few cells, re-saving the file) the XML mappings are missing in target file.

Solution which reproduces the issue is attached.

Feel free to ask for additional details.

Thanks for providing us sample project with template files.

I observed the issue as you mentioned by using your sample code with your template file. The template file does contain XML maps for certain elements (we can check certain elements are mapped (are set bold) in XML Source window in MS Excel) which lose their mappings in the output Excel file by Aspose.Cells.
Sample code:

string inOutPath = String.Concat(Environment.CurrentDirectory, @"\InputOutput");
string fileName = “DPH13xx_FINAL.xlsx”;
string outFileName = String.Concat(“Modified_”, fileName);
string fullFileName = Path.Combine(inOutPath, fileName);
string fullOutFileName = Path.Combine(inOutPath, outFileName);

string newValue = “3”;

Workbook workBook = new Workbook(fullFileName);
Worksheet dicWorksheet = workBook.Worksheets[“DPH1”];

Cell dicCell = dicWorksheet.Cells[“J21”];

Style dicCellStyle = dicCell.GetStyle();
dicCellStyle.IsLocked = true;

Stream fileStream = File.Create(fullOutFileName);
workBook.Save(fileStream, SaveFormat.Xlsx);

Console.WriteLine(String.Concat("Saved ", fullOutFileName));
Console.WriteLine(“Press any key to exit.”);

I have logged a ticket with an id “CELLSNET-42849” for your issue. We will look into it soon.

Once we have any update on it, we will let you know here.

when we finished our product and tried to move it to production we are fighting “the same” issue again (the sample file is different, the original file seems to be working).

I have attached new sample application which reproduces the bug.
