I have an existing web application that uses call back methods.
Since updating to Service pack 1 of Visual Studio, creating a new Web Application and importing some of the existing functionality into the new project I am getting a:
<script type="text/javascript">
<!--
WebForm_InitCallback();// -->
At the bottom of pages that is causing and "Object Expected" error?
I have checked that the .axd extension is correctly mapped in IIS as other posts suggested.
Any suggestions on how to fix this ??
