RegisterStartupScript, Ajax and external script <p>I have a page that is run using AJAX. I have a control that is wrapped in a RadAjaxPanel that has multiple child controls in it. The RadAjaxPanel is updated when new items are selected. I also have a 3rd party javascript that needs to refresh during the callback.</p> <p>Here is my problem.</p> <p>When the callback happens, I use </p> <pre><code>ScriptManager.RegisterStartupScript(this.Page, this.Page.GetType(), "RecommendationScript", "&lt;script src='3rdparty.js'&gt;&lt;/script&gt;, false); </code></pre> <p>This doesn't appear to work after the callback happens since I am not seeing the results. Even if I create a test external script that does a javascript alert, I won't see the alert after the callback. Everything works fine though if I don't use an external script and just put the alert in the RegisterStartupScript. However, that won't work for what I need to do.</p> <p>Any ideas?</p>
