if we talk about the onclick event, then it's easy. However once Ulrich is talking about link control - I'd be interested to know if it's somehow possible to manipulate the
url of the link from an action on the page - say its own onclick event - for example to add an additional
parameter.
The problem probably is that the link url gets calculated on page load.
So it cannot know what docs will get selected. You can process the docs
in the onclick event but cannot change the link url. or there is a way - in onclick event it finds the link control and modifies it? can it work?
