Hi guys I have a wpf application that is using the mvvm pattern, in my application I have two view model, One controls my main window and the other control my page. I want to be able to bind my login page UI element to my LoginViewModel? Any idea on what to do thanks below is my code for my two view model
Main Window view model
#region Displayed page
private Uri displayedPage;
public Uri DisplayedPage
{
get
{
return this.displayedPage;
}
set
{
this.displayedPage = value;
base.OnPropertyChanged("DisplayedPage");
}
}
#endregion
#endregion
#region Constructor
public MainWindowViewModel()
{
LoginViewModel _login = new LoginViewModel(this);
}
#endregion
while the view model for my page
#region Constructor
public LoginViewModel(MainWindowViewModel _mainwin)
{
_mainViewModel = _mainwin;
_mainViewModel.DisplayedPage = new Uri("/View/AuthenticationView/LoginPage.xaml", UriKind.RelativeOrAbsolute);
}
#endregion
