Have trouble understanding wpf visual studio setup

I have a wpf project setup by visual studio. I'm trying to create MVP classes, but I cannot access any xaml properties in these classes that I've created (e.g. textBox1.text or label.Content)

Files they gave me were MainWindow.xaml.cs, MainWindow.xaml and some other files. I can access those xaml properties in MainWindow.xaml.cs. But in my view.cs it show 'textBox' does not exist in the current content. Appreciate any extra details and info

MainWIndow.xaml.cs:

namespace myApp
{
public partial class MainWindow : Window
{
    private Model model;
    public MainWindow()
    {
        InitializeComponent();
        //initialize the storage
        model= new Model();
    }

    /// <summary>
    /// clear the textbox for user input
    /// </summary>
    private void clearInput()
    {
        textBox1.Text = ""; //these works fine
        textBox2.Text = "";
        textBox3.Text = "";
    }

[...]
}

view.cs:

namespace myApp
{
public interface IView
{
    void clearInput();
}

public class PView: IView
{
    public void clearInput()
    {
        textBox1.Text = ""; //error
        textBox2.Text = "";
        textBox3.Text = "";
    }
 }

You need to give the controls (TextBox etc) in your XAML file a name, like this

<TextBlock Name="textblock1" .....

Then in your code file you can access textblock1

EDIT

However, these controls are allways private, so not visible to other classes. To make the data public you need to try something like this:

public string TextBlockText
{
   get { return textblock1.Text; }
}

And then in your other classes you can use 

var text = MainWindow.TextBlockText;

EDIT2

Alternatively, you can make these controls public like this

<TextBox x:Name="textBox1" x:FieldModifier="public" />
