c# running a javascript and a codebehind function on same button?

Hi all,
not sure if this is possible becuase a .net button on click has a value of javascript:dopostback_ etc


but basically, i want a code behind function to run then a javascript one i can make it do one or the other and at the moment the code is only doing the javascript one and ignoring the c# one

any ideas on how i can do this?
