DelegateCommand Newbie Question

I'm trying to get up to speed with PRISM and how it works with Silverlight/WPF. Is it possible to using DelegateCommands to open a new popup (Silverlight Window). If so, how would I go about doing something like this.

Most of the samples I've seen so far involve using DelegateCommands to retrieve data (or some other similar action).

If anyone has any suggestions开发者_如何学JAVA, I'd appreciate it.

I use the delegate command to essentially execute a method and/or pass data back to the ViewModel.

A popup, is a presentation facility, so I don't see anything wrong with adding an event handler to a button and loading up a popup from codebehind. I would suggest a more infrastructure/reusable approach by either creating some sort of IDialogService or instantiating your popups ViewModel/View and exposing the View via view injection or binding to a content control.
