从内容页面中的updatepanel更新母版页的内容

Question

I need to update content of master's master page in order to update shopping cart totoal price. I have a updatepanel in content page from where user add products. How can i update master's master contents/ label on click of button inside update panel.

Answer 1

As updatepanel async refresh updates its own area only, it is not possible to refresh another area (shopping cart total price). One solution is to add another updatepanel around shopping cart total control and refresh it from serverside code when your main update panel refreshes/

Answer 2

You can update that by using FindControl property . Have a look at this article

Answer 3

I faced a problem like this a few days ago, I solved it with jQuery.

1. Give the total shipping label a CSS class
2. Use jQuery to call that class form the jQuery script and update it's text.
