FieldMergeBarcode.AddStartStopChar property

Gets or sets whether to add Start/Stop characters for barcode types NW7 and CODE39.

public bool AddStartStopChar { get; set; }


Shows how to perform a mail merge on CODE39 barcodes.

// 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 "MyCODE39Barcode" column into CODE39 barcodes.
FieldMergeBarcode field = (FieldMergeBarcode)builder.InsertField(FieldType.FieldMergeBarcode, true);
field.BarcodeType = "CODE39";
field.BarcodeValue = "MyCODE39Barcode";

// Edit its appearance to display start/stop characters.
field.AddStartStopChar = true;

Assert.AreEqual(" MERGEBARCODE  MyCODE39Barcode CODE39 \\d", field.GetFieldCode());

// 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 CODE39 barcode with the value from the merged row.
DataTable table = new DataTable("Barcodes");
table.Rows.Add(new[] { "12345ABCDE" });
