Page doesn't postback if it has validation control after deployment
<p>I have a page with a RadioButtonList which should post back when the selection is changed. But because of RequiredFieldValidator on the page, the postback is not happening.
It is working fine on //localhost/ but not after deployment to production server.</p>

<p>The error on the page is:
'event' is null or not an object
<br>Line: 126
Char: 5
Code: 0</p>

<p>URI: <a href="http://web-dev:90/aspnet_client/system_web/2_0_50727/WebUIValidation.js" rel="nofollow">http://web-dev:90/aspnet_client/system_web/2_0_50727/WebUIValidation.js</a></p>

<p>A few things which I have already tried:</p>

<p>1) aspnet_client folder is in its proper place.</p>

<p>2) I have added <code>Page.Validate() and if(Page.IsValid){}</code> statements with the button on whose click the validation should happen.</p>

<p>3) The ValidatorCommonOnSubmit function in <code>WebUIValidation.js</code> file looks like this:
<pre><code>
   function ValidatorCommonOnSubmit() {
    event.returnValue = !Page_BlockSubmit;
   Page_BlockSubmit = false;
   return event.returnValue;}
</pre></code>
Can somebody help me with this? Any help would be appreciated. Thanks!!</p>
