如何在回发时加载带有冻结标题的页面内容？

Question

I'm using asp.net and c#.net. I'm gonna implement a website that has content navigation like that Microsoft did on this link: Microsoft Windows

In this link you're able to browse page content with freeze header on postback and also you're able to browse videos from left Navbar without page postback. The important thing is for each click url is changed.

Any ideas or help would be appreciated.

Thanks and regards

First off, to clarify, postbacks are only required if you're submitting form elements. If you're creating a webforms application, you can easily use controls like HyperLink with a NavigationUrl to navigate among URLs without needing postbacks.

If what you mean is that you're seeing the page partially updating when following links, that's not what I'm experiencing. The pages appear to completely reload when the links in that page are clicked. In your own site, you can use AJAX and JavaScript to implement a navigation system that doesn't require heavy navigation requests. Look at Manipulating the browser history (MDN) for information on exciting new JavaScript features that will let you modify the browser's URL/history without reloading the page. There are several JS libraries that integrate with this feature to give you "AJAX" navigation capabilities.

To simply get the header to not scroll along with the rest of the page, use position: fixed in the CSS for the element.
