Konstantina Chremmou 8f51089efe CP-5752: Use Action delegate instead of EventHandler when there is no need to 
pass in parameters when the event is fired. Moved QueryElement.Dispose method
from the Designer.cs to the main file (it needs visibility since it contains more
code than the autogenerated method).
