asp.net-ajax

I'm a .NET programmer who've just started to learn more about client side scripting, and I was wondering sometimes you use $get('value') and $find('value') and I've discovered that these are just shortcuts for document.getElementById('value') and Sys.Application.findComponent('value') , respectively.

I need to pass some data (integer values and some strings) to the user control that has been loaded dynamically .
