title: WPF Changing the size of my textbox when i cover it with my cursor
body: <p>In my program i have various textboxes which are too small for the text the user will want to write in, so i want to change the size of my Textbox when i hover my cursor over it. 
  As soon as i leave the Textbox with my mouse it should go back to the normal size.</p>
  
  <p>maybe with the MouseEnter Event.</p>
  
  <p><code>MouseEnter="Protokolbox1_MouseEnter"</code></p>
  
  <p>Thank you for your help.</p>
