I have the following definition of rad date picker:
<telerik:RadDatePicker ID="calStartUsingDate" runat="server" DateFormat="dd/MM/yyyy">
<ClientEvents OnDateSelected="calcConsump" />
</telerik:RadDatePicker>
I tried to get the selected date of it, but the following statment always returns null !!
start = $find("<%=calStartUsingDate.ClientID %>");
Use this outside of your OnDateSelected function:
var start = $find("<%=calStartUsingDate.ClientID %>").get_selectedDate();
OR if you are using it in the OnDateSelected function it would look something like...
function calcConsump(sender, args){
var start = sender.get_selectedDate();
}
