Today’s code sample illustrates the use of Sys.Application.add_load to add an handler to Sys.Application.load event.  And the handler, usually scripted by users, can successfully access DOMs generated by AJAX control toolkit. Otherwise, by simply placing a <script> tag in the page, it may not find the DOMs and their attributes as expected.
 
This sample comes up because when some of the users use client side methods, such as  getElementById() and getElementsByTagName() to access DOMs generated by AJAX control toolkit, they fail to get the attribute(s) of some specific DOMs. So, they can't script to add features at client side to meet their personal needs or project's requirement by ASP.net technology.
