Populating label text from a hyperlink

Just a quick question to see if anyone knew if this is possible

[Jimmy Turnip]

Is it possible in asp.net to populate text of a label dynamically depending on the hyperlink that is pressed on the same page?

My current solution is simply having the hyperlinks point to the current page with a select case statement dependant on the querystring. Is there a way I can do this dynamically without the page having to reload? A bit like when you have a regular expression validator and the error message text appears dynamically on the page, even without the page being posted back.

You need to use javascript for this. You want to use the getElementById method and toggle the display element of your layer. I would not use a label because you won't know what the id will be. Also make sure you don't run your div at server.
