Copy listitem between Listviews

Hi,

I want to temporarily hide some rows in a listview if the user select a specific filter optional button. On the other hand, if the user selects 'Show All' filter, I will show all of them. My question here is if there is a quicker way to COPY LISTITEM if I want to move those 'hiden' list itmes to a invisiable backup listview? For example: set itmBackup=itmOriginal

Any suggestion?

Thanks.

Regards,

Michi
