If I use fiddler it doesn't even look like there is additional traffic or a new request created.

问题 Inside a webpage I have an Excel download button, which redirects to a webpage that serves the requested Excel file via the application/ms-excel MIME type, which usually results in a file download in the browser.

问题 Is it possible to create a SharePoint (wss3 or MOSS 2007) webpart, to allow files to be dragged and dropped onto it, which would then upload the files into a predefined document library ? I imagine that this would require some form of client side scripting (Ajax ?), but my knowledge in ajax is a bit sketchy.

问题 I have an asp.net 2.0 page that contains 2 UpdatePanels . The first panel contains a TreeView control, when I select a node in the three view control it triggers an update of the second UpdatePanel only. This much is behaving correctly.

问题 Just a quick question for all of you guys. I have a Grid View inside Update Panel. My Modal PopUp pulls this Panel up. I am good so far. However when I try to do pagination on the popped up grid view, The page Posts Back. Then the Modal PopUp disappears and so does my GridView.

问题 I'm trying to add a realtime progress report to my c#/asp.net 4.0 application for a slow loading page. I've look at the UpdatePanel and UpdateProgress Ajax controls but I don't think they're suitable.

The order thing would happen would be: 1. user click button to start 2. call method 1 3.
