Closing RadDateRangePicker popup

[SSirica]

Is there a way to close the date range popup automatically once the end date has been chosen?  I know you can close it by clicking somewhere outside the popup, but users are dumb and that may not be intuitive enough.

Here is a basic example leveraging the client-side API of the DateRangePicker control: 

<telerik:RadDateRangePicker RenderMode="Lightweight" ID="RadDateRangePicker1" runat="server">
    <ClientEvents OnDateSelected="OnDateSelected" />
</telerik:RadDateRangePicker>
<script>    
    function OnDateSelected(sender, args) {
        if (sender.get_endDatePicker().get_selectedDate() != null) {
            sender.hidePopup();
        }
    }
</script>
