Public Events
 NameDescription
Public EventRaised when a QueryAutoFilterDistinctValues event has been raised for a page of data that is no longer needed and whose corresponding AsyncQueryInfo object's EndQuery method has not yet been called, allowing the pending operation to be canceled and preventing useless processing on the data server.  
Public EventRaised when a QueryGroups event has been raised for a page of data that is no longer needed and whose corresponding AsyncQueryInfo object's EndQuery method has not yet been called, allowing the pending operation to be canceled and preventing useless processing on the data server.  
Public EventRaised when a QueryItemCount event has been raised for a page of data that is no longer needed and whose corresponding AsyncQueryInfo object's EndQuery method has not yet been called, allowing the pending operation to be canceled and preventing useless processing on the data server.  
Public EventRaised when a QueryItems event has been raised for a page of data that is no longer needed and whose corresponding AsyncQueryInfo object's EndQuery method has not yet been called, allowing the pending operation to be canceled and preventing useless processing on the data server.
