blurring a web page in silverlight

i have a web page that has to go dim on page load and some box comes over.

the box has to have a TextBox. this box takes some input from 开发者_如何学Pythonthe user. and on click

on a submit button the TextBox info is to be checked on server and then accordingly the already dimmed web page may go normal(usable) or keep dimmed.

very much like what happens on opening the home page of www.sulekha.com

please guide me on this.

thankQ

have you tried using the ChildWindow in the Silverlight Toolkit, does that not give you the intended "modal" + "grey out background" behaviour
