Using Code

This example code sets Codabar in the worksheet.

// Create a new workbook
var workbook = new GrapeCity.Documents.Excel.Workbook();

// Set worksheet layout and data
IWorksheet worksheet = workbook.Worksheets[0];
worksheet.Range["B:F"].ColumnWidth = 20;
worksheet.Range["4:7"].RowHeight = 60;
worksheet.Range["A:A"].ColumnWidth = 5;
worksheet.Range["B2"].Value = "Codabar";
worksheet.Range["B2:F2"].Merge(true);
worksheet.Range["B3:G3"].Value = new object[,]{
{"Name", "Number", "Defult", "Change checkDigit", "Change nwRatio"}
};

worksheet.Range["B4:C7"].HorizontalAlignment = HorizontalAlignment.Center;
worksheet.Range["B4:C7"].VerticalAlignment = VerticalAlignment.Center;
worksheet.Range["B2:F3"].HorizontalAlignment = HorizontalAlignment.Center;
worksheet.Range["B2:F3"].VerticalAlignment = VerticalAlignment.Center;
worksheet.Range["B4:C6"].Value = new object[,]
   {
    {"Notebook", "6935205311092"},
    {"Paper", "6922266446146"},
    {"Value can contain letters and some symbol", "A1234+-/.$A"}
   };
worksheet.Range["B4:C6"].WrapText = true;
worksheet.Range["G6"].WrapText = true;
worksheet.PageSetup.Orientation = PageOrientation.Landscape;
worksheet.PageSetup.PrintGridlines = true;

// Set formula
for (var i = 4; i < 7; i++)
{
   worksheet.Range["D" + i].Formula = "=BC_CODABAR" + "(C" + i + ")";
   worksheet.Range["E" + i].Formula = "=BC_CODABAR" + "(C" + i + ",,,,,\"true\")";
   worksheet.Range["F" + i].Formula = "=BC_CODABAR" + "(C" + i + ",,,,,,\"2\")";
}

// Save to a pdf file
workbook.Save("codabar.pdf");

Limitation

  • The "checkDigit" parameter takes effect only when the 'value' parameter's length is 13 and the barcode's label text does not change.
