Get the id of the selected Item in richselect

Hi,
Is there a way(method) through which one can get the id of the selected Item in richselect

onChange event is one way:

I used this.getList().Qc; and I have no idea if Qc property is reliable for the future. Qc property has id value but I used for loop to get whole object.

List has a public “getItem” method. It will be better to use it instead of private methods.
