How to update row formula fields

[conniem]

I have a template where there are row based formulas i.e. c2+d2 and g2 - e2
When I’m cloning and inserting new rows, how would I deal with the formulas like that? (because the clone logic is keeping the formula as is, and I need to update it to c[insert current row index here] + d[insert current row index here], for each row, and each row’s index may change as the document is built.
attached is a project for an example. if you look in the test.dot template, there are ‘row based’ formulas in 2 of the cells.
if you look in result.docx, they are clone, but the index part of the formula doesn’t update based on current row, and I need them to be updated.

@conniem,

You can update the index values inside formula field by using the following code:

Document doc = new Document(MyDir + @"fields\result.docx");
Table table = doc.FirstSection.Body.Tables[0];

for (int i = 0; i < table.Rows.Count - 1; i++)
{
    Row row = table.Rows[i];

    foreach (Field field in row.Range.Fields)
    {
        if (field.Type == FieldType.FieldFormula)
        {
            FieldFormula formula = (FieldFormula)field;

            string fieldCode = formula.GetFieldCode();
            string numericFormat = formula.Format.NumericFormat;
            string targetString = fieldCode.Replace(numericFormat, "");
            string replaced = Regex.Replace(targetString, "[0-9]", "" + (i + 1));                       

            Node currentNode = formula.Start.NextSibling;
            bool isRemoving = true;
            while (currentNode != null && isRemoving)
            {
                if (currentNode.NodeType == NodeType.FieldSeparator)
                    isRemoving = false;

                Node nextNode = currentNode.NextPreOrder(currentNode.Document);
                currentNode.Remove();
                currentNode = nextNode;
            }

            Run run = (Run)formula.Start.NextSibling;
            run.Text = replaced + numericFormat;

            formula.Update();
        }

    }
}

doc.Save(MyDir + @"fields\18.5.docx");

@conniem,

Please spare us some time for the investigation of this scenario. We will update you the earliest possible.

@conniem,

I have commented the following method call from the end of your “testMerge” method

finishMergeTable(m_Table);

and generated result.docx (see result.zip (9.2 KB))

After that for this result.docx, I executed the exactly same code from my previous post and managed to produce correct final output (see 18.5.zip (9.2 KB)).
