updatepanel

I've tried the specially for that scenario designed methods of the scriptmanager, but the javascript just doens't get returned to the user.

问题 I am having what I believe should be a fairly simple problem, but for the life of me I cannot see my problem. The problem is related to ScriptManager.RegisterStartupScript, something I have used many times before. The scenario I have is that I have a custom web control that has been inserted into a page.

问题 I am adding a click event (display alert on click) to a html hyperlink inside an UpdatePanel on document(ready). However, the event never gets fired when I click the hyperlink.

问题 This is a simple question, NikhilK answered to this question: "Script# doesn't support ASP.NET Ajax anymore" Does that mean that we can't use Asp.net UpdatePanels (which need a ScriptManager) in the same page where we load mscorlib.js? Even if mscorlib is manipulating DOM elements that are not inside the updatepanel? 回答1: When I mentioned asp.net ajax is not supported, it is primarily a two-fold statement: MSAjax assemblies allowing you to program against the msajax scripts are no longer
