// Add a list template so that the data is formatted as a list: var myListTemplate = doc.ListTemplates.Add(BuiltInListTemplateId.BulletDefault, "myListTemplate");
// The only paragraph added to the document will print the sequence number // fetched from the first data source (the sequence master), and the ocean name // fetched from the second data source (the sequence follower): var p = doc.Body.Paragraphs.Add("{{#nums}:seq(seq1)}{{nums.num}} -- {{#ds}:follow(seq1)}{{ds.name}}{{/ds}}{{/nums}}", doc.Styles[BuiltInStyleId.ListParagraph]); p.ListFormat.Template = myListTemplate;
// This call expands all data templates in the document, // replacing template tags with data (iterating over all data items): doc.DataTemplate.Process(CultureInfo.GetCultureInfo("en-US"));
