Apply Mergefield and replace by another mergefield

[Tuan Ardouin]

Hello,

Is it possible to replace a mergefield by another mergefield when executing it ?
My goal is to show the user the result of the mergefield but to keep the ability to do a mergefield later.

Something like :

string field_name = "mergield_code"
string[] fieldNames = {field_name}

field_value = new MergeField(field_name, "New field value")

string[]fieldValues = {field_value}

document.MailMerge.Execute(fieldNames, fieldValues)

Thanks,
Tuan

  2. Execute mail merge.
  3. Using MergeField event, get the index of merge field and paragraph.

  5. Insert new merge field in the same index of paragraph.
  6. Saves the Word document.

Hello,

Thank you for this sample and sorry for not responding.

In your example you used 

paragraph.AppendField(fieldName, FieldType.FieldMergeField);

This add a mergefield to the document but with a code equal to the label. Is it possible to have a control over the MERGEFORMAT when inserting an element of type FieldMergeField.

My final goal is to always keep the code of the mergefield, and change only the label.

Thank you,

Tuan
