title: How to manipulate a window object from another class in WPF
body: <p>I'm new in WPF and C#. I know a lot of VB.NET and I'm used to the way when I call a form object like textboxes, etc. I'm calling it from another form. Now, I'm using WPF, I'm confused. Because I have a Main Window. And I want to add and item to a listbox in the Main Window from a Class. In VB.Net , its just like this. </p>
  
  <pre><code>    IN FORM2
  
      Form1.Textbox.Text = "";
  </code></pre>
  
  <p>Wherein I can't do it in WPF. Can someone please Help me. Thanks!</p>
