title: "Enter" key not leaving cell in RadGridView
body: <p>All around my project I'm facing similar problem, which is "Enter" key, creating new line in cell, instead of move to next line. </p>
  
  <p>My current telerik version is 2018.1.122.45, and default, expected behavior is to leave cell, after pressing "Enter" key (according to telerik documentation, and helpdesk). </p>
  
  <p>However, in my case it always makes new line within cell being edited. 
  I'm using Visual Studio 2013 theme, my implementation of RadGridView is correct, I've pasted my RadGridView, to project, I got from telerik support, and there, Enter was working as expected. Also, they've pasted my RadGridView implementation to their project and it also worked correctly. </p>
  
  <p>Have anyone faced similar problem? I'm looking for solution, since I can't track source of this issue (even with teleriks help).</p>
