title: Why the cells turn blank when they lose the focus in the GridView?
body: <p>When I fill a cell, no matter the type of, this turns empty when it lose the focus. </p>
  
  <p>At the same time I cant add a new row (with tab or enter) in a GridView (I got the AllowAddRows=True and the NewItemRowPosition = Bottom properties).
  I hope you can help me with this problem. Thank you.</p>
