Our WebCombo is being generated in the code, and is being added to a control under an UpdatePanel. If the UpdatePanel uses a PostbackTrigger, it works fine. However, if we use an AsyncPostbackTrigger, we are receiving the error, "The value of the property 'ISControl_InitializeAtlas' is null or undefined, not a Function object" and the WebCombo is not rendered properly. Please see attached sample page.</p> <p> </p> <p>I can confirm that the runtime licenses are supplied correctly on our web.config and that the ISNet.dll, ISNet.WebUI.dll, ISNet.WebUI.Resources.dll are on our website's bin folder, as indicated on some of the responses to similar problems I've found on this forum. If you notice, I also tried to add the &lt;system.webServer /&gt; tags on our web.config. All these did not resolve the error we're encountering.</p> <p> </p> <p>This is happening on my local machine (Windows 7, VS2010) and on our app server (Windows Server 2008, IIS7).</p> <p> </p> <p>We need to use the AsyncPostbackTrigger in this page as we have other controls that would be affected. Please help!</p> <p> </p> <p>Thanks!</p> <p>-- Art</p>
