Silver Error Provider

Question

Is there a error provider for silverlight or something equivalent.


I want to basically throw a errorprovider icon, image, or text in red to let the user no that they have not
input no text into a textbox. The user must validate required textbox input before moving to the next page.  If they have not put any text in the textbox some form of information will be display to remind the user.

can some one point me into the right direction?
