Some time ago I received a question on the Wrox P2P forum about checkboxes that should behave like radio buttons. The poster of the question was looking for a (client side) solution to have multiple checkboxes per row in a GridView with multiple rows. A user should only be able to check off at most one of the checkboxes in each row. My first thought was to use radio buttons instead, but then I realized that with radio buttons you lose the ability to uncheck all options. Once you've selected a radio button in a group of radio buttons, there's no way for an end user to uncheck it again.
Fortunately, with a bit of jQuery, this is really simple to accomplish with checkboxes as I'll show you in this short article.
Don't you just hate it? You find a good article somewhere on the Internet and you decide to print it so you can read it later. But when you read it, you find out that all the links in the article are missing. All you see is something like "Click here to read this other very interesting document". On the web site, the word here links to some kind of other document, but on paper that is pretty useless. The only option you have left is to revisit the original article, find the link and follow it.
