    copied!<p>In my asp .net form, I refresh a control using Ajax through the AjaxPro library. However, after doing so...causing any "normal" postback results in a yellow screen (Complete error after the message)</p> <p>I've set the following Page properties in web.config without any luck</p> <pre><code>&lt;pages enableSessionState="true" enableViewState="false" enableEventValidation="false" enableViewStateMac="false"&gt; </code></pre> <p>I've also tried generating a machine key as some solutions suggested online. But that doesn't help either.</p> <p>Any suggestions?</p> <p>*******************Contents of ASP .NET yellow screen************************************</p> <pre><code>Server Error in '/' Application.
