title: Change field value in the cxgrid when changing another
body: <p>In my cxGrid I have a Yes/No field which is by default 'NO' . Next to that field, I have another field,a LookupComboBox field that
  gets its values from another table. It is empty by default however I would like that, when the value gets changed in this
  particular field, my Yes/No field should change to 'YES' (Only in the row that I am currently editing) How am I to do this ? Also Not sure where to implement the code ....OnChange,Oneditvaluechanged,Onvalidate ???</p>
