onBeforeSelect

fires before selection of an item is started

id	string|number	id of the item
state	boolean	the selected state of the item (true when item is selected by action)

boolean

true - to trigger the default action, false - to block it

Example

myDataView.attachEvent("onBeforeSelect", function (id, state){
    // your code here
    return true;
});

The event is blockable, returning false will block the default action.

In case of multi-select, the event fires only for items which were clicked, and it doesn't fire for the items which were selected by Shift-click or similar actions.
