Checking if the page IsValid in Javascript?!

[Emilio]

Hi,

I have a form that contains various server validation controls, the submit
button will either open a popup box or a popup window on the client-side
click event. The question is, how do I check if the page is valid before it
gets posted back to the server so the window or box only pops up if
everything is OK? At the moment the popup occurs first then the validation.

Many thanks

Emilio

Hi,

client-side script has also Page_IsValid flag to indicate the status of the
validation. See this article for details:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnaspp/html/aspplusvalid.asp

Basically the cient-side checking you need to develop yourself but the tools
you need exist in the client-side validation API

Hi,

Thanks for the reply, unfortunatly the my client-side onclick event seems to
be taking place before the Page_IsValid flag is updated from its default
true state. Is their any way I can get around this. The onclick attribute is
added in the last the last line of code in my page load event.

thanks

It is updated right when Page_ClientValidate is called. On the article, I
mentioned, is also explained how to check the status validator by validator.
You can call Page_ClientValidate yourself also.

Thanks Teemu,

Got it working 100%, the article doesn't mention the Page_ClientValidate
function however.

Thanks again

Horrible MSDN documentation... ASP.NET Validation in Depth

ASP.NET Validation in Depth - title says validation in depth and does not discuss about Page_ClientValidate() function...

ends with overconfident line

"That's It
This is probably more than you wanted to know about ASP.NET validation. Have fun with it! "

he is a piece*, Quality by Microsoft documentation goes SUCCCCCCCCKS!

Hi,
I have 2validators on my page i.e Custom validator and a Required feild validator.Both have diffferent validation group.Custom validator gets fired only on Delete button click wheres the Required feild Validators are supposed to be fired on Add and Update button.

I am using java script to do so..and is showing Validation summary on a pop-up control.

The issue is when i call the Page_ClientValidate() method and check the Page_IsValid property..i always get it false..since the custom validator method is even been called out..which i dont want.
Please help.
