Examples

Shows to insert PAGEREF fields and present them in different ways.

public void FieldPageRef()
{
    Document doc = new Document();
    DocumentBuilder builder = new DocumentBuilder(doc);

    InsertAndNameBookmark(builder, "MyBookmark1");

    // This field will display just the page number where the bookmark starts
    // Setting InsertHyperlink attribute makes the field function as a link to the bookmark
    Assert.AreEqual(" PAGEREF  MyBookmark3 \\h", 
        InsertFieldPageRef(builder, "MyBookmark3", true, false, "Hyperlink to Bookmark3, on page: ").GetFieldCode());

    // Setting the \p flag makes the field display the relative position of the bookmark to the field instead of a page number
    // Bookmark1 is on the same page and above this field, so the result will be "above" on update
    Assert.AreEqual(" PAGEREF  MyBookmark1 \\h \\p", 
        InsertFieldPageRef(builder, "MyBookmark1", true, true, "Bookmark1 is ").GetFieldCode());

    // Bookmark2 will be on the same page and below this field, so the field will display "below"
    Assert.AreEqual(" PAGEREF  MyBookmark2 \\h \\p", 
        InsertFieldPageRef(builder, "MyBookmark2", true, true, "Bookmark2 is ").GetFieldCode());

    // Bookmark3 will be on a different page, so the field will display "on page 2"
    Assert.AreEqual(" PAGEREF  MyBookmark3 \\h \\p", 
        InsertFieldPageRef(builder, "MyBookmark3", true, true, "Bookmark3 is ").GetFieldCode());

    InsertAndNameBookmark(builder, "MyBookmark2");
    builder.InsertBreak(BreakType.PageBreak);
    InsertAndNameBookmark(builder, "MyBookmark3");

    doc.UpdateFields();
    doc.Save(ArtifactsDir + "Field.PAGEREF.docx");
}

/// </summary>
private static FieldPageRef InsertFieldPageRef(DocumentBuilder builder, string bookmarkName, bool insertHyperlink, bool insertRelativePosition, string textBefore)
{
    builder.Write(textBefore);

    FieldPageRef field = (FieldPageRef)builder.InsertField(FieldType.FieldPageRef, true);
    field.BookmarkName = bookmarkName;
    field.InsertHyperlink = insertHyperlink;
    field.InsertRelativePosition = insertRelativePosition;
    builder.Writeln();

    return field;
}

/// <summary>

private static void InsertAndNameBookmark(DocumentBuilder builder, string bookmarkName)

    builder.EndBookmark(bookmarkName);
}
