Adding a Link to a Cell in the Same File

It is possible to add hyperlinks to cells in the same Excel file by calling the Hyperlink collection’s Add method. The Add method works for both internal and external hyperlinks.

C#

 Workbook workbook = new Workbook(); // Creating a Workbook object

Worksheet sheet = workbook.Worksheets.Add("Hyperlinks");

HyperlinkCollection hyperlinks = sheet.Hyperlinks;

Style style = new Style();

style.Font.Underline = FontUnderlineType.Single;

style.Font.Color = System.Drawing.Color.Blue;

sheet.Cells[0, 0].Value = "URL Link";

hyperlinks.Add(0, 0, 1, 1, "http://www.aspose.com");

sheet.Cells[0, 0].SetStyle(style);

//link to a file in the current directory

sheet.Cells[1, 0].Value = "File Link";

hyperlinks.Add(1, 0, 1, 1, "book1.xls");

sheet.Cells[1, 0].SetStyle(style);

//e-mail link

sheet.Cells[2, 0].Value = "Email Link";

hyperlinks.Add(2, 0, 1, 1, "mailto:marketplace@aspose.com?subject=Hyperlinks");

sheet.Cells[2, 0].SetStyle(style);

//link to a place in this workbook

Worksheet sheet2 = workbook.Worksheets.Add("Target ISheet");

HyperlinkCollection hyperlinks2 = sheet2.Hyperlinks;

sheet2.Cells[3, 0].Value = "Worksheet Link";

hyperlinks2.Add(3, 0, 1, 1, "Target ISheet!A4");

sheet2.Cells[3, 0].SetStyle(style);

workbook.Save("test.xlsx");

Adding a Link to an External File

It is possible to add hyperlinks to cells in the same Excel file by calling the Hyperlink collection’s Add method. The Add method works for both internal and external hyperlinks. One version of the overloaded method takes the following parameters:

  • Cell name,the name of the cell the hyperlink will be added to.
  • Number of rows, the number of rows in this hyperlink range.
  • Number of columns, the number of columns in this hyperlink range.
  • URL, the address of the target cell.

C#

 //Instantiating a Workbook object

Workbook workbook = new Workbook();

//Obtaining the reference of the first (default) worksheet

Worksheet worksheet = workbook.Worksheets[0];

//Adding an internal hyperlink to the "B9" cell of the other worksheet "Sheet2" in

//the same Excel file

worksheet.Hyperlinks.Add("B3", 1, 1, "Sheet2!B9");

//Saving the Excel file

workbook.Save("C:\\book1.xls");

C#

 IWorkbook workbook = new XSSFWorkbook();

////cell style for hyperlinks

////by default hyperlinks are blue and underlined

ICellStyle hlink_style = workbook.CreateCellStyle();

IFont hlink_font = workbook.CreateFont();

hlink_font.Underline = FontUnderlineType.Single;

hlink_font.Color = HSSFColor.Blue.Index;

hlink_style.SetFont(hlink_font);

ICell cell;

ISheet sheet = workbook.CreateSheet("Hyperlinks");

//URL

cell = sheet.CreateRow(0).CreateCell(0);

cell.SetCellValue("URL Link");

XSSFHyperlink link = new XSSFHyperlink(HyperlinkType.Url);

link.Address = ("http://poi.apache.org/");

cell.SetCellValue("Email Link");

link = new XSSFHyperlink(HyperlinkType.Email);

//note, if subject contains white spaces, make sure they are url-encoded

link.Address = ("mailto:poi@apache.org?subject=Hyperlinks");

cell.Hyperlink = (link);

cell.CellStyle = (hlink_style);

//link to a place in this workbook

//Create a target sheet and cell

ISheet sheet2 = workbook.CreateSheet("Target ISheet");

sheet2.CreateRow(0).CreateCell(0).SetCellValue("Target ICell");

cell = sheet.CreateRow(3).CreateCell(0);

cell.SetCellValue("Worksheet Link");

link = new XSSFHyperlink(HyperlinkType.Document);

link.Address = ("'Target ISheet'!A1");

cell.Hyperlink = (link);

cell.CellStyle = (hlink_style);

FileStream sw = File.Create("test.xlsx");
