Examples

Shows the relationship between mail merges with regions, and field updating.

public void MergeWholeDocument(bool mergeWholeDocument)
{
    Document doc = CreateSourceDocMergeWholeDocument();
    DataTable dataTable = CreateSourceTableMergeWholeDocument();

    // If we set the "MergeWholeDocument" flag to "true",
    // the mail merge with regions will update every field in the document.
    // If we set the "MergeWholeDocument" flag to "false", the mail merge will only update fields
    // within the mail merge region whose name matches the name of the data source table.
    doc.MailMerge.MergeWholeDocument = mergeWholeDocument;
    doc.MailMerge.ExecuteWithRegions(dataTable);

    // The mail merge will only update the QUOTE field outside of the mail merge region
    // if we set the "MergeWholeDocument" flag to "true".
    doc.Save(ArtifactsDir + "MailMerge.MergeWholeDocument.docx");

    Assert.True(doc.GetText().Contains("This QUOTE field is inside the \"MyTable\" merge region."));
    Assert.AreEqual(mergeWholeDocument, 
        doc.GetText().Contains("This QUOTE field is outside of the \"MyTable\" merge region."));
