Methods

Name Description
GetFieldCode() Returns text between field start and field separator (or field end if there is no separator). Both field code and field result of child fields are included.
GetFieldCode(bool) Returns text between field start and field separator (or field end if there is no separator).
Remove() Removes the field from the document. Returns a node right after the field. If the field’s end is the last child of its parent node, returns its parent paragraph. If the field is already removed, returns null.
Unlink() Performs the field unlink.
Update() Performs the field update. Throws if the field is being updated already.

Examples

Shows how to perform a mail merge on QR barcodes.

Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);

// Insert a MERGEBARCODE field, which will accept values from a data source during a mail merge.
// This field will convert all values in a merge data source's "MyQRCode" column into QR codes.

field.BarcodeType = "QR";
field.BarcodeValue = "MyQRCode";

// Apply custom colors and scaling.
field.BackgroundColor = "0xF8BD69";

    field.GetFieldCode());
builder.Writeln();

// Create a DataTable with a column with the same name as our MERGEBARCODE field's BarcodeValue.
// The mail merge will create a new page for each row. Each page will contain a DISPLAYBARCODE field,
// which will display a QR code with the value from the merged row.
DataTable table = new DataTable("Barcodes");
table.Columns.Add("MyQRCode");
table.Rows.Add(new[] { "ABC123" });
table.Rows.Add(new[] { "DEF456" });

doc.MailMerge.Execute(table);

Assert.AreEqual(FieldType.FieldDisplayBarcode, doc.Range.Fields[0].Type);
Assert.AreEqual("DISPLAYBARCODE \"ABC123\" QR \\q 3 \\s 250 \\h 1000 \\r 0 \\b 0xF8BD69 \\f 0xB5413B",

// 2 -  EAN13 barcode, with the digits displayed below the bars:
