title: WPF New Window with content
body: <p>I want create a new Window beside an existing main Windwoe with a scrollable Textbox.</p>
  
  <p>I'm pressing in my main Window on a button "Open New Window" and then it should open a new Window with a scrollable Textbox.</p>
  
  <p>inside <code>form2</code></p>
  
  <p>In WPF you can drag drop elements in the main Window but cant do that for a new window.
  So I thought it is only possible when you create a new window in the MainWindow.xaml.cs</p>
  
  <p>I was able to create a new Window trough:</p>
  
  <pre><code>private void btnConnect_Click(object sender, RoutedEventArgs 
   {
      Form form2 = new Form();
      //Do intergreate TextBox with scrollbar in form2
  
      form2.Show();
  
   }
  </code></pre>
  
  <p>and now I want a Textbox</p>
  
  <p>But how can I do that in C# or WPF?</p>
  
  <p>Thx</p>
