This widget has problems.
1) The regular expression within the RegularExpressionValidator control of edit.ascx is much too restrictive. Entering a valid URL such as
http://www..test.com will render "Please enter a valid URL"
2) Edit doesn't work, no updates are made. The only thing you can do is delete the entry and re-add it with the change
3) When in edit mode, Cancel doesnt work
4) Delete works until the last item. It actually deletes it but doesnt show it within the LinkList window until you close it and go back in
