.net 2.0 credit card validator

[Eirik Eldorsen]

Hi

Does anybody know of a credit card validator for .net 2.0?
For .net 1.1 i'm using this great validator:
http://www.codeproject.com/aspnet/creditcardvalidator.asp
But I can't get it to work with masterpages :-(

How do you know? What error(s) are you getting?

The error I get is controltovalidate is null or not an object.

I'm guessing that the control can't find txtCardNr since it's id becomes
ctl00_cphMainContent_txtCardNr when using masterpages. Am I wrong? Have you
used the control with masterpages?

UPDATE:
The error I recieve: document.all.CreditCardValidator1.controltovalidate is
null or not an object

This is probably because the masterpage renames CreditCardValidator1 to
ctl00_cphMainContent_CreditCardValidator1

I've created a workaround:
The thing that is'nt working is the clientscript, so I set the variable:
EnableClientScript="False" on the validator.
Now I only get a serverside check, which works perfect. And since I'm using
Ajax the users won't notice the postback to the server :-D

You can use something like the following to ensure "unmangling" of control
names:



private string script = "[Label1ID].innerHTML = 'boo!';";
private string scriptKey = "hello";
private bool addScriptTags = true;
protected void Page_Load(object sender, EventArgs e)
{
script = script.Replace("[Label1ID]",Label1.ClientID);
ClientScript.RegisterStartupScript(this.GetType(), scriptKey, script,
addScriptTags);

Nice trick

But to use this, do I have to rewrite the source of the validator? (i'm only
using a ddl file now)
