From 2 monts ago i´ve developing with this framework or suite package telerik, while i was program some aspx pages i founded some stop times for get or mapping the radcontrols from javascript file my great reason for write this post !!
for mapping a control on our javascript we have put the next propertie ClientMode="Static" like
<telerik:RadTimePicker ClientIDMode="Static" DateInput-DateFormat="HH:mm:ss" Style="position:absolute; top:220px; left:500px" ID="_dtpMonthlyHour" runat="server">
</telerik:RadTimePicker>
and our javascript file mike this //.
var _dtpMonthlyHour=$telerik.findDatePicker("_dtpMonthlyHour");
with this line of code we can get all we want about this radControl !!
