title: Delphi Cannot change this property when using LiveBindings
body: <p>Can anybody explain to me what the error message "<em>Cannot change this property when using LiveBindings</em>" is telling me?</p>
  
  <p>I am new to FMX / Live Bindings and I had something working, but I changed a few things and now, I am getting this error when trying to bind the fields of a TFDMemTable to a TGrid.</p>
  
  <p>I had the same fields from the same table bound to the grid before!</p>
