    I'd like to be able to catch the onClientItemClicking event and be able to determine what the previously selected item was. Is this possible? Also, if it is, I would like to fire a server side event based on what the previous selected item was.
    Basically, what I am trying to do is to do an automatic "save" on whatever it is that they were working on prior to navigating someplace else.
    Thanks ... Ed

    Hey Ed,

    My guess would be to store the value of the selected item into a hidden field that you can pull out later, something along the lines of...

    <user click>

    if hiddenfield has value, run through code relating to previous item

    set hiddenfield value to itemclicked

    do whatever other click logic there was

    Carries your value through post-back, lets you react based on previous item, and after the first click you'll always have that value saved moving forward.

    Yeah, that was my fallback. I guess I was hoping there might be something built in. No biggie.
    Thanks ... Ed
