reading client changed values on the server for asp.net page

[gus]

Hi folks,

I have a asp.net page with html controls (span and anchors) whose
innerhtml and display properties are changed on the client with
javascript. I also have buttons that postback to the server and my
problem is that when the page is rendered back to the client, the
client changed controls, as I would expect, are back to the original
state; instead, I would like to keep the last page status as changed on
the client side by the user. Is there a way to do that? Is there a way
to access client changed properties for controls like span or anchors
on the server side? Even if i use the "runat=server" attribute the
server is still not aware of all the changes I make on the client.

Thanks a lot
