How to get header template control on postback from another control on aspx page

Im wondering how to get a label control that is in a header template in a datalist on an aspx page. I need the control text to change when the user checks a checkbox outside of the list on the page somewhere. I tried It开发者_Python百科emdatabound, but I dont want to have to rebind the list everytime the user checks the box (lots of slow reaction time)

Any ideas? Thanks
