Hello Pravallika,

You could try using the appraoch below:

<telerik:RadDateTimePicker ID="rdtpAppointments_StartTime" SelectedDate='<%# Bind("StartedOn") %>' runat="server">
  <DateInput>
    <ClientEvents OnValueChanged="OnDateSelected" />
  </DateInput>
</telerik:RadDateTimePicker>

<telerik:RadDateTimePicker ID="rdtpAppointments_EndTime" runat="server"/>

JS:

function OnDateSelected(sender, eventArgs) {

    var endTimePicker = $find("<%= rdtpAppointments_EndTime.ClientID %>");

    var newValue = new Date(eventArgs.get_newDate());
    var oldValue = new Date(eventArgs.get_oldDate());
    var difference = Math.round((newValue - oldValue) / 86400000);

    var oldDate = new Date(endTimePicker.get_selectedDate())
    var newDate = oldDate.setDate(oldDate.getDate()+difference);

    endTimePicker.set_selectedDate() = newDate;
  }
