Hi there,

Take a look at this:


You set the ClientIDMode to static which means ASP.NET changes the way IDs are rendered. In the article, I mention the ClientIDMode and then show the code you need to use instead (which is much simpler):
var userNameTextBox = $get('UserName'); 
var userNameRequiredMessage = $get('UserNameRequired');
So either get rid of the ClientIDMode, or use this simpler code instead. The article has full details on this.
