How can I access my View elements via x:Name from my Presenter?

Question

My presenter defines its own view :

public SmartFormPresenter(SmartFormView view)
{
    View = view;
    View.DataContext = this;
}

In the view I have an element with x:Name="MainTabControl":

<DockPanel LastChildFill="True">
    <TabControl x:Name="MainTabControl" DockPanel.Dock="Top" ItemsSource="{Binding SmartFormAreaPresenters}">
        <TabControl.ItemContainerStyle>
            <Style TargetType="{x:Type TabItem}">
                <Setter Property="Header" Value="{Binding Title}"/>
            </Style>...

How can I access this element as I do in code behind, something like this:

PSEUDO-CODE:

View.Root.Children.MainTabControl.Visibility = Visibility.Collapsed;

Answer 1

You can define a public property in your view that will expose the private field. Or better, don't do it and define some abstract property in your view, like "IsViewTabbed" or sth like this, that will abstract UI code out of presenter.

Answer 2

Found it:

TabControl mainTabControl = View.FindName("MainTabControl") as TabControl;
mainTabControl.Visibility = Visibility.Hidden;
