I am using 2 datetimepickers and a control validator to make sure the end date of something is after the start date but it is not working. I am receiving the error message of the validator no matter what I put in the end date. Please can you tell me what I am doing wrong.
Many thanks

<telerik:RadDateTimePicker ID="dpStartTime" runat="server">

<asp:RequiredFieldValidator ID="RequiredFieldValidator2" runat="server" ControlToValidate="dpStartTime"
ErrorMessage="RequiredFieldValidator">Start date required</asp:RequiredFieldValidator>

The RadDatePicker, RadTimePicker, and RadDateTimePicker controls can work seamlessly with standard ASP.NET validation controls.

I have already looked at the examples in the demos and the documentation. In fact I took the validator within my code from one of your demos. However my code is not working and I cannot see why. I was hoping you might look at it and see if you can identify the error.
thanks
