title: How do I activate an in-place editor for a grid cell that displays as a progress bar?
body: <p>One of the cells in my DBTreeListView is bound to a repository item that is a progress bar. </p>
  
  <p>I want to be able to edit the progress displayed by clicking on this cell. At this stage my application should change its cell to another repository item: a text field where I'll be able to insert a value. Once focus is changed to another cell, my progress bar should be displayed again, showing a new value. How do I do this?</p>
  
  <p>DBTreeListView has column events <code>OnGetEditingProperty</code> and <code>OnGetEditProperties</code>. I'll probably use one (or both) of them, but can't come up with any good idea.</p>
