    Hi All,
    I have a panelbar set up in FullExpandedItem mode.
    Inside one of these I have a grid that scrolls.  I have found that on a callback, the grid loses it's scroll position, so I need to track that. Ok, I have that working.
    My issue comes when my scrolling code is fired before the expand animation is complete - basically, once the animation is complete, the grid scroll position gets set back to the top.
    I have solved it partially by choosing an arbitrary setTimeout number to make my scrolling code fire after the expand animation has finished, but I am having trouble finding out what this is meant to be!
    I have an ExpandAnimation Duration of 200, 0 Delay, type OutQuart, but for some reason, I need to wait 500 ms to run my code.  Why is this?  If I use the Duration, it is too soon.  The client event OnClientItemExpand seems to occur when the expansion starts, so is no good to me.
    Is there a reliable way to find out whether the animation has completed so that my scrolling code will work without a pause and reliably?
    Thanks,
    Steele.

    Hi Steele,

    Have you tried using the ClientItemAnimationEnd event of RadPanelBar?
    I think this solves it!
