title: Selected textbox in datagrid is indenting on click
body: <p>I am working on a user interface issue which is when I click on an item in the grid and it makes the textbox editable, the first byte is indenting so you can see it is selected.</p>
  <p>The user does not want this this way, but I have been searching for a solution but I have yet to find it... I already tried to make it non focusable but that makes no difference.</p>
  <p>I am using C# WPF, a DataGrid which contains these textboxes.</p>
