Change wpf user control using devexpress mvvm

Question

I'm trying to change the UserControl in my mainwindow. I'm using devpress's poco viewmodels.

The main window displays except for where the loginView should be it displays "LoginViewModel_xxxxxx"

The LoginView.xaml is a UserControl.

I have

MainWindow.xaml

    <Grid Row="1">
        <ContentControl Content="{Binding CurrentViewModel}"/>
    </Grid>

MainWindowViewModel.cs

public virtual object CurrentViewModel { get; set; }

public static MainWindowViewModel Create()
{
   return ViewModelSource.Create(() => new MainWindowViewModel());
}
protected MainWindowViewModel()
{
   CurrentViewModel = LoginViewModel.Create();
}

LoginViewModel.cs

public static LoginViewModel Create()
{
    return ViewModelSource.Create(() => new LoginViewModel());
}

protected LoginViewModel()
{
    //unrelated code
}

Try to define a DataTemplate for the LoginViewModel:

<ContentControl Content="{Binding CurrentViewModel}">
    <ContentControl.Resources>
        <DataTemplate DataType="{x:Type local:LoginViewModel}">
            <local:LoginView />
        </DataTemplate>
    </ContentControl.Resources>
</ContentControl>

Just a note to whoever uses this; if your `ContentControl` can be any number of different view-model types, you need to have multiple DataTemplates defined in the resources, one for each type. – Bradley Uffner Aug 16 '18 at 09:51
