I can’t give you some code because, It’s a big module with a lot of code.
But I have follow the link :

Thanks

Hi

Thank you for additional information. I used the following code for testing and all works fine on my side:

// Create dummy datasource
DataTable dt = new DataTable("MyTable");
dt.Columns.Add("col1");
dt.Columns.Add("col2");
for (int i = 0; i <10; i++)
    dt.Rows.Add(new object[]
    {
        "val1",
        "val2"
    });
// Open template
Document doc = new Document(@"Test001\in.doc");
// Add MergeField event handler
doc.MailMerge.MergeField += new MergeFieldEventHandler(MailMerge_MergeField);
// execute mail merge with regions
doc.MailMerge.ExecuteWithRegions(dt);
// Save output doc.
doc.Save(@"Test001\out.doc");

void MailMerge_MergeField(object sender, MergeFieldEventArgs e)
{
    // Do something in MergeField event
    if (e.FieldName == "col1" || e.FieldName == "col2")
        e.Text = "this text was writen from MergeField event";
}

Best regards.
