Thanks Andrew,
Actually, I am using AJAX 1.0 officially release. For time being, I just let it go since I can build from design view. And I got one more question, after migrating to AJAX 1.0, the TAB not working properly, for example, click checkbox to display and panel, but the cursor will go to top of page. when I use 'Atlas', I can use Focus( ) to force cursor stay on the check box. But now the Focus not working anymore, Do you have any idea?
Thanks,
Sean
