How to call a view from a view model using MVVM pattern

Question

Hello I have two view models A and B. On a double click on view A I need to display view B. How can I call a view B from a view Model A using the MVVM pattern. I have looked around and I couldn't find a clear example that demonstrate this fundamental concept for the MVVM pattern. Thank you

I think you may need to create an object and invoke it.

Hi Tapan Here is what I'm trying to do: using Microsoft.Practices.Prism.Commands; using Microsoft.Practices.Prism.Mvvm; using System.Windows.Input; namespace Example.ViewModels { public class ViewModelA:BindableBase { public ICommandShowInfoCommand{ get ; private set ;} //Need to call viewB private void OnShowInfo( object obj) { //ToBeImplemented } } }
