IsValueChanged Method

This is the overview for the IsValueChanged method overload.

 
Name 
Description 
 
Asks whether the value for a field has changed after the reception of this update. For the first update for the item, it always returns true.
If the "COMMAND logic" behaviour is enabled, then the change is meant as relative to the same key; as a consequence, on ADD commands the method always returns true; moreover, on DELETE commands the method returns true for all fields, but for the "key" field.
