With GoDiagram Web, how can I add a hyperlink into a node?
Are you asking how a user would do it interactively, or how a programmer would do it through code?
Showing how a programmer would do it, sir. Sorry for the confusion.
GoWebIntro.doc shows you how to do it on the server – search for “hyperlink”.
There’s lots of customization you can do here – it’s described in GoWebIntro.doc.
