Update EndDateTime when StartDateTime is updated for RadDateTimePicker

[Mark]

When my form is loaded I'm setting StartDate to now and EndDate to now+1 hour. I'd like to have the EndDate (month/time/year, not time) update whenever the StartDateTime is updated. This project is within Sitefinity.

I've tried a few different methods but nothing seems to work out. My latest attempt:

<telerik:RadDateTimePicker ID='dtEventBegin' runat='server'>
<DateInput ClientEvents-OnBlur="changeEndDate" />
</telerik:RadDateTimePicker>

<telerik:RadDateTimePicker ID='dtEventEnd' runat='server' />

<telerik:RadScriptBlock ID="RadScriptBlock1" runat="server">
        function changeEndDate(sender, e)
        {
            var endDatePickerID = sender.get_id().replace("dtEventBegin", "dtEventEnd");
            var endDatePicker = $find(endDatePickerID);
            endDatePicker.set_selectedDate(sender.get_selectedDate());
        }
</telerik:RadScriptBlock>

I'm not finding very many usage scenarios for the DateTimePicker, can I please get some help?

Hello Mark,

I have followed your scenario and prepared a sample project for you demonstrating how the desired functionality can be implemented. You can find it attached to this message.

I hope it helps.

Kind regards,

Mira, that works exactly as I wanted. The only caveat is that it also makes the buttons for the Date & Time pickers disappear. Do you have any insight into why that would happen?

Edit: Updating to latest tools fixed the problem.
