I'm a javascript/VS 2008 ASP.NET novice.

When I hit the command button (Edit) on the page, when I intentionally put in a wrong domain, it doesn't come up with any messages to show that the validation is working. From the tech books I have, it shouldn't be a hard thing. What am I doing wrong? I think my code is okay.

Got an .aspx form that uses a master page. In the .aspx form in the Content Place Holder I have a table with a field call txtEmail with a CustomValidator control associated with it. What I want the client-side validation to do is make sure the user puts in the company's domain for email.

Properties for the CustomValidator are set to this...
ClientValidationFunction cvCheckEmail
ControlToValidate txtEmail
Display Dynamic
Error Message Work Email only!
Text ***

fyi - isValid was not a selection in Intellisence. In a training manual I have it shows it. IsValid does come up on the server-side validation, but not here.

<script type="text/javascript">
function cvCheckEmail(src, args)
{
try {
var uInput = args.valueOf;
var uHowLong = uInput.length;
var oEmail = "mycompany.com";
var oHowLong = oEmail.length;
var odiff = 0;
var oString = "";

if (uHowLong > oHowLong) {
odiff == uHowLong - oHowLong;
oString == uInput.substring(odiff,oHowLong);
args.IsValid = (oString == oEmail);

}
catch(e) {

args.IsValid = false;
}
}

Should I be putting this code on the master page in the <head> tag area or should it be in the content place holder on the .aspx page? Tried both places, but it still doesn't work.

All feedback is greatly appreciated!
