title: How to set the margin on a internal TextBoxView in wpf
body: <p>I have a case where I want to minimize the horizontal padding of a textbox.</p>
  
  <p>Using snoop I found that the textbox consists of a multiple sub-controls.
  One of them is a TextBoxView with a margin of 2,0,2,0</p>
  
  <p>The TextBoxView is an internal wpf component and has no public API.</p>
  
  <p>How would you approach getting rid of the "internal padding"??</p>
