Hi, I have have two user controls on a single umbraco page and would like to force a refresh on one after an update on the other.

There is a shopping cart in the main part of the page and a seperate User Control (shopping cart summary box) in the header.

I have written the Quantity and Total price to a session variable and want some some sort of event handler so the cart summary user control will get updated on the fly without reloading the entire page (maybe AJAX?)

i am a little lost as not used to using multiple user controls.

thanks in advance.
