How to check the Checkout and checkin of List Items in Event Receivers


To check is the List Item has been checkout or checkin the below code snippet will help.


If vti_sourcecontrolcheckedoutby of AfterProperties is null and vti_sourcecontrolcheckedoutby of  BeforeProperties is NOT null then the event is caused by Checkin.


if (properties.AfterProperties["vti_sourcecontrolcheckedoutby"] == null 
&& properties.BeforeProperties["vti_sourcecontrolcheckedoutby"] != null) 
{ 
    // event is fired by check-in. 
} 
else 
{ 
    // events fired  other than check-in . 
}




Note : Better to use EventFiringEnabled=false at the starting point of the function in the event receiver (Item updating,Item Adding etc....)
and at last, make to true.
EventFiringEnabled=true.  Which avoids unnecessary event firing of List items
