Page_IsValid Problem

malie22001 · December 21st, 2011, 01:22 AM

Hi guys,

I am trying to implement the exact same code that Imar implemented in the book. Besides the point where he implemented it in a user control, I am implementing it directly in the Contact Us page.

Here is my code.

Code:

$(function ()
        {
            $.watermark.options = {
                className: 'fontSize',
                useNative: false
            }
            $('#<%= fullNameTextBox.ClientID%>').watermark('Enter your full name...');
            $('#<%= emailTextBox.ClientID%>').watermark('Enter your email address...');
            $('#<%= contactNoTextBox.ClientID%>').watermark('Contact No...Eg: 610-931-1281');
            $('#<%= commentTextBox.ClientID%>').watermark('Enter your comment...');

            $('form').bind('click', function ()
            {
                if (Page_IsValid)
                {
                    $('#ContactFormDiv').slideUp('3000');
                }
            });

        });

I am using a different watermark plugin. This one can be found at . It is extremely easy to use.

The problem I am having is that the Page_IsValid doesn't seem to be recognized. When I comment it out, the code works. In case you are wondering, I have the ScriptManager in the master page.

Can anyone tell me what I'm doing wrong?

Thank you.

Page_IsValid comes from the client side validation framework. Does your page contain standard asp.net validators?

Cheers,

Yes, I am using the standard ASP.net validation controls. If you want I could provide the code for the entire page.

Yes, that would be helpful. Please create a page with just a minimal implementation to reproduce the problem (e.g. no master page, base page, database dependencies and so on). Also, please supply a link (or the script) for the plugin. Then I can try to reproduce the problem.

Cheers,

Imar

Hi Imar,

Thank you again. I think its the order in which I put the reference links in the master page. I put the jQuery reference above all other references and its now working. Also when I tried it, I hadn't included any logic in the code behind of the page.

The question now though is, what does the ScriptManager render as? How does it fit in ehn talking about script references?

Thanks always.

PS: Here is the link for the watermark I used.

The ScriptManager mainly lives on the server. What it does is dynamically include JavaScript files for client side behavior. Check out the final HTML of a page in the browser and you'll see what I mean: you'll see a number of <script /> elements with their source set to a long and cryptic file name. Some of those have been added by the ScriptManager to support behavior for stuff like the UpdatePanel and client side web service calls.

Cheers,

Imar
