I am trying to replace mergeField with Text from my database. I have done this before with version 2.5 and it worked perfectly (.Net framework 4). I tried doing the same with .Net Core by using it with .Net standard but its giving issues. I tried debugging and found out its not finding mergeFields inserted into the document. So i copied, Cleared the document and pasted it and then it worked. after then i tried to edit it and changes did not reflect. i tried copy and paste again and it was the same merge field that is fetched. its wierd. here is a code snippet. please help.
using (WordprocessingDocument _document = WordprocessingDocument.Open(filePath, true))
{
_document.ChangeDocumentType(WordprocessingDocumentType.Document);
_document.GetMergeFields("ref_no").ReplaceWithText(refNo);
_document.MainDocumentPart.Document.Save();
mergeFields = _document.MainDocumentPart.RootElement.Descendants<FieldCode>().ToList();
for (int i = 0; i < request.Data.Count; i++)
{
if (request.Data[i].ControlTypeId == (int)FormControlTypeEnum.DATE)
{
_document.GetMergeFields("v" + request.Data[i].Index.ToString().Trim()).ReplaceWithText(DateTime.Parse(request.Data[i].Data).ToShortDateString());
_document.MainDocumentPart.Document.Save();
}
else if (request.Data[i].ControlTypeId == (int)FormControlTypeEnum.MONEY)
{
_document.GetMergeFields( request.Data[i].Index.ToString().Trim()).ReplaceWithText(string.Format(formatter, "{0:c}", double.Parse(request.Data[i].Data)));
_document.MainDocumentPart.Document.Save();
}
else
{
_document.GetMergeFields(request.Data[i].Index.ToString().Trim()).ReplaceWithText(request.Data[i].Data);
_document.MainDocumentPart.Document.Save();
}
}
////document.GetMergeFields(newDoc.jsonFields[i].controlName).ReplaceWithText(newDoc.jsonFields[i].data);
////document.MainDocumentPart.Document.Save();
}
public static IEnumerable<FieldCode> GetMergeFields(this WordprocessingDocument doc, string mergeFieldName = null)
{
if (doc == null)
return null;
List<FieldCode> mergeFields = doc.MainDocumentPart.RootElement.Descendants<FieldCode>().ToList();
foreach (var header in doc.MainDocumentPart.HeaderParts)
{
mergeFields.AddRange(header.RootElement.Descendants<FieldCode>());
}
foreach (var footer in doc.MainDocumentPart.FooterParts)
{
mergeFields.AddRange(footer.RootElement.Descendants<FieldCode>());
}
if (!string.IsNullOrWhiteSpace(mergeFieldName) && mergeFields != null && mergeFields.Count() > 0)
return mergeFields.WhereNameIs(mergeFieldName);
return mergeFields;
}
I had to downgrade t a lower version of the library to get things to work
