Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequestHandler); function EndRequestHandler(sender, args) { $('img.ormdShipping').each(function(){ $(this).qtip({ // some qtip options go here }) }); } Problem is, the jQuery doesn

阅读更多关于 Response.Redirect in ASP.NET AJAX calls

I have a button in an UpdatePanel that if it is clicked will redirect the user to another page in the same folder in some cases and otherwise will update the UpdatePanel with some info. If I do a redirect in this way: Response.Redirect("Test.aspx"); it does a redirect to /Test.aspx which in most cases would be fine, but the problem is that the application is accessed through a reverse proxy (at x.com/y/) which will cause some problem since /Test.aspx will redirect the user to a nonexisting file in the root of the server that does the proxying. Is it possible to force the redirect to skip the /

问题 Let me start of by saying that I am inexperienced with JavaScript. Here is what I want to do. When the user clicks "Show Details" on a row of data, they get a pop-up (modal?) window that has some data generated from another action within the MVC application. Where can I find an example of implementing something like this?

How can I programmatically add triggers to an ASP.NET UpdatePanel?

After the page loads, the drop downs are there, with their data, but changing them does not call the SelectedIndexChanged event handler, nor does the QuoteUpdatePanel update. I have something like this: Edit: Since programmatically adding
