Invoking a postback before a large ASP.NET page has fully rendered
will often cause the page to crash. This is unhelpful and confusing
to users.
I'm wondering if I can overcome this by disabling any controls that
invoke a postback until the page is fully rendered, ie setting the
controls disabled server-side, serving the page and then having a
JavaScript routine right at the bottom of the page re-enable them
client-side.
Has anyone tried this successfully?
Thanks,

I'm not positive on this, but it sounds like the JavaScript onload event
is what you're looking for. Basically, you'd load the page with the
button disabled, by default. According to the documentation the onload
event fires after the page finishes loading. If that's the case, you
would simply enable the button in your onload event handler. http://www.w3schools.com/jsref/jsref_events.asp
Hope that helps,

That's certainly the way I do it...
I agree that the onload event is preferred.
In simple cases placing the JavaScript at the bottom of the page will work,
but for more complex pages things may not yet be fully initialized by that
point.

The script below will disable Submit button until user accept terms,

The script seems to work fine on my PC (Windows XP, IE6), however I

who knows how to write these codes properly. Please let me know if
there're any logic errors.

I have a PHP application which I wrote last year - and the JavaScript

When I click on my HTML link now (which executes a JS function), the

Error: document.SubjectsForm.submit is not a function
Any help would be much appreciated. Thanks!

Hi,
I wonder how to disable the "submit" behavior of a button. What I want is to
assign values to dynamically added user controls without page postback.
Problem: dynamically created control can not be accessed because the button
click trigers page postback(see sample code). When the button is clicked, an
error occurs: "System.NullReferenceException: Object reference not set to an
instance of an object."
Please help. Thanks.

This is a solution... Often users want to keep clicking "submit" when
they are waiting for server processing. Most apps these days like to
disable the submit button to prevent this. You can't just disable the
button in the OnClick event in ASP.Net because then the Click event
won't post to the server (because you disabled it). I searched google
groups, and there is a solution to this problem, but I didn't think it
was clean enough and...
