Based off the sample on MSDN, the following works at changing the view based on a change in the ViewModel. The only difference I can see with your code is the use of DynamicResource:

    

      
        
          
            
          
          
          
        
      

      
        
          
          
          
        
      

      
        
        
      

      
        
          
            
            
            
            
          
        
      

      
        
          
        
      

      
        
        
        
        
      
      
      

    

    

  
    
      
        
          
          
          
        
      


    
    
      CurrentView: 
    
    
      Right-click in the content window to change the view.
      

  
 

Code behind file:

using System;
using System.Windows;
using System.Windows.Controls;

namespace SDKSample
{
    /// 

    /// Interaction logic for Window1.xaml
    /// 

    public partial class Window1 : Window
    {
        public Window1()
        {
            InitializeComponent();
        }

        public MainViewModel ViewModel
        {
            get { return this.DataContext as MainViewModel; }
        }

        void SwitchViewMenu(object sender, RoutedEventArgs args)
        {
            MenuItem mi = (MenuItem)sender;
            ViewModel.ViewName = mi.Header.ToString();
        }

        private void Window_SourceInitialized(object sender, EventArgs e)
        {
            ViewModel.ViewName = "gridView";
        }
    }
}

And finally the ViewModel class:

using System;
using System.Collections.Generic;
using System.Text;
using System.ComponentModel;

namespace SDKSample
{
    public class MainViewModel : INotifyPropertyChanged
    {
        public string ViewName
        {
            get { return viewName; }
            set
            {
                if (viewName == value)
                    return;

                viewName = value;
                NotifyPropertyChanged("ViewName");
            }
        }
        private string viewName;

        public event PropertyChangedEventHandler PropertyChanged;

        void NotifyPropertyChanged(string name)
        {
            if (this.PropertyChanged != null)
                this.PropertyChanged(this, new PropertyChangedEventArgs(name));
        }
    }
}
