Attributes clear on post back

I am using Attributes.Add("style", "color:green") with some checkboxlists and radiobuttonlists.  When I click one of the checkboxes and I do the autopostback the attributes clear out.  So I would think someone already has a sub to fix this.  Something like:
 
SaveAttributes(checkboxlist1) or SaveAttributes() 'which would loop though all controls and save the state.
 
and then on pageload it would have
LoadAttributes(checkboxlist1) or LoadAttributes() 'which would loop through all controls and restore the state.
