Hi guys I have a WPF application that is using MVM pattern. In the application I have a frame that host my page a and b, however when I change view from page a to b, and try to change my view back to page a, it does not bring me a new page instead it brings back page a with its old state. How can I stop that? Below is my code for both my xaml and view model


<MenuItem Header="Operator" Visibility="{Binding Path=MenuVisibility, Converter={StaticResource BooleanToVisibilityConverter}}"
                          Command="{Binding Path=ViewMenuCommand}" />
<Frame Grid.Row="1" Name="MainAPpFrame" NavigationUIVisibility="Hidden"
                Source="{Binding Path=DisplayPage, Mode=TwoWay}" HorizontalContentAlignment="Stretch" VerticalContentAlignment="Stretch" />

my view model

private Page displayPage;
        public Page DisplayPage
                return displayPage;
                if (displayPage == value)
                this.displayPage = value;
public ICommand ViewMenuCommand
                if (_operatorViewMenuCommand == null)
                    _operatorViewMenuCommand = new RelayCommand(
                        param => this.ProcessNavRequest());
                return _operatorViewMenuCommand;
private void ProcessNavRequest()
            //string uri = String.Format("/View/{0}", parameter);
            this.DisplayPage = new OperatorView();
