问题 I want to delete a row in a Database table when a user closes an .aspx page. How could I do it? I know how to delete a row in a Database table but I don't know how to do it when a user leaves an .aspx page? 回答1: You can bind an ajax call to the "beforeunload" page html event. Just make sure to call ajax with async false, otherwise the page will be close before the code to delete the row actually runs. I'm assuming you are using jQuery for the ajax call. For example, in html: <body

问题 I am seeing a really wierd issue that only happens with non-administration users. When the user logs in and accesses one page, they are logged out of the system. The page finishes loading as if they were logged in, but once they try any other actions (including refreshing the browser page) they are considered not logged in and presented with a login prompt. Opening up fiddler, I can see one of the responses from the server contains the following: Response sent 71 bytes of Cookie data: Set

ASHX handler with ASP.NET MVC 3 and Razor

问题 I would like to use Silverlight Multi File Uploader with ASP.NET MVC 3. The problem is that I need to use ashx handler to handle file upload (the handler is part of the library). How can I integrate the handler with ASP.NET MVC 3 (I'm using Razor view engine) ? 回答1: My guess is that it is easier because it is part of a (older?) third party library and it easier to just follow the instructions that tells you to set something in web.config . You should be able to ignore requests to *.ashx by

问题 I'm about to launch a site that was working well until I found the following hiccup: I can't request a Yahoo! Pipe over SSL. So the pages that require SSL are now missing a piece of their functionality unless I figure out a way around this; obviously, this could be done if I use an SSL-hosted page on my app to request the Yahoo! pipe for me. I've seen solutions like http://www.iisproxy.net/license.html, but it seems to be a bit heavy for what I'm trying to do. Can't I do this with a simple

问题 I need a image generator in my ASP.NET MVC application, but I don't know if it is possible to use ASHX in ASP.NET MVC. If there is an class similar to IHttpHandler that inherits IViewDataContainer, then I could use ViewData.Model on my ASHX. I read a blog post about it but it seem outdated from the info I got in the ASP.NET forum Any ideas? 回答1: You should just be able to return the image from the action? See here for more. And yes, you can use ashx alongside MVC (by telling it to ignore the
