When the user click on the ShowCheckAll button either all entries aree selected or unselected. Looking at the documentation I cannot find any event that is fired for that. Even if there is no specific event for that, I would expect that ClientEntryAdded or ClientEntryRemoved for each of the entries would be fired but thatis not the case either.
I need to handle this event as part of a logic that checks if and when the set of selected items is changed. Is there any other way to get notified via an event when ShowCheckAll is clicked ?
