grouplist

So I am trying to make a grouplist that is filled by a hidden list… The problem I have is as click through listitem(0) content changes based on the current item. To solve this I have two controls image controls based on the dbtype of the current item. This works fine other then a blinking as it will show both images for a milsecond…. Is there easy way to set set item one as listitem 1 item 2 as listitem 2 and so on so as I click thru it not have the blinking?

Hopefully this makes a little sense.
