Silverlight pop-up Non-model Windows?

In Silverlight, how do I popup non-model windows? I want that user to 开发者_开发百科interact with the parent window as well as child window at same time. What can I do?

You have to implement your own window... Good way to do it is to have a canvas on top of your UI, after you will display window as child of that canvas and will be able to interact with your UI as well.
