Server validation

cnickl

VS 2003 / .NET 1.1 / C#

Iâ€™m playing with some validation controls. I have noticed that I can
validate a dropdownlist with a custom validator using the following format:

<asp:customvalidator id="valPayment" Runat="server" Display="Dynamic"
ControlToValidate="XXX" EnableClientScript="False"><img
src="Error.jpg"></asp:customvalidator>

And than doing some custom code in the â€˜valPayment_ServerValidateâ€™ function.

Why canâ€™t I use the same asp:customvalidator for a radiobuttonlist? I tried
it and as long as there is nothing selected, the code in the code behind file
is not executing. But I canâ€™t seem to attach a asp:requiredfieldvalidator to
a radiobuttonlist. I get an error message that the radiobuttonlist canâ€™t be
found. Any explanation for that?
