C1.Pdf.C1PdfDocument.AddLink

AddLink Method

AddLink(string, RectangleF)

Adds a hyperlink to the current page.

Declaration
public void AddLink(string url, RectangleF rc)
Parameters
Type Name Description
string url

Link destination (can be a Url, a file name, or a local link destination).
RectangleF rc

Area on the page that will behave as a link (expressed in points, from the top-left corner of the page).

AddLink(string, int, RectangleF)

Adds a hyperlink to the document.

Declaration
public void AddLink(string url, int page, RectangleF rc)
Parameters
Type Name Description
string url

Link destination (can be a Url, a file name, or a local link destination).
int page

Index of the page that contains the hyperlink
RectangleF rc

Area on the page that will behave as a link (expressed in points, from the top-left corner of the page).
Remarks
<p>Hyperlinks can be external (Urls and file names) or local (other locations within the same document).</p>
<p>Local links are useful when you want to implement some type of cross-referencing within the document, such

as a table of contents or an index. Local links are identical to regular hyperlinks, except for two things:

1) The url parameter must start with a "#", and

2) You must specify the target location for the link using the AddTarget method.

Note that the AddLink method does not add any visible content to the page, so you will usually need another command along with AddLink to specify some text or an image that the user can see, as the example below demonstrates.

Examples

The code below adds a string that says "Visit site" and a link that takes the user to the ComponentOne home page:

Rect rc = new Rect(50, 50, 100, 15);                            // RectangleF
Font font = new Font("Arial", 10, PdfFontStyle.Underline);      // FontStyle
_c1pdf.AddLink("http://www.google.com", rc);
_c1pdf.DrawString("Visit site", font, Color.Blue, rc);  // Brushes.Blue
