Still Trying to Understand Validation

[Jonathan Wood]

Looking at the page loaded into the browser, I found the following inside of
<form></form>:

<input type="image" name="ContinueButton" onclick="if
(typeof(Page_ClientValidate) == 'function') Page_ClientValidate(); "
language="javascript" id="ContinueButton"
src="http://localhost/[...]\Continue.gif" border="0" />

Doesn't this suggest that Page_ClientValidate() should be a routine on the
page somewhere? I searched for "Page_ClientValidate" and only found it above
and for one other control that looked much like this one.

Can anyone help me understand these lines?

Thanks.

Yes. But the function could also be embedded with in a .js file. In this case Page_ClientValidate should be in the following location on your computer(version may be different) C:\Inetpub\wwwroot\aspnet_client\system_web\1_0_3705_0\WebUIValidation.js. It could also be under C:\Inetpub\wwwroot\<YOURPROJECT>\aspnet_client\system_web\1_0_3705_0\WebUIValidation.js. If you can't find it there then search for it

The function gets wired to handle the onclick event of a control by .NET if validation is happening

Okay, found it. Thanks.

Can you tell me what happens in the case of a CustomValidator control? It
would seem that would need to work on the server side because it has a
custom event that must be processed. Is that right?

A CustomValidator object can do client side validation too. Set the
property ClientValidationFunction with the name of the custom
client-side script function, and send a <script> block to the client
with the function in jscript or vbscript.

 

[Jonathan Wood]

Makes sense (what little I understood of it anyway). I'll look into this.

Thanks.

Thanks. Looks like the sample given only uses server-side validation but
I'll look into it further.

Yes. Like Scott said customvalidator can do client side validation as well.

It could also be under

lidation.js. If you can't find it there then search for it. by .NET
