Yeah, moving the mouse off the tree and then back again to see the new toolTip text is exactly what I was talking about. The event fires correctly, it just seems that dynamically changing the toolTip that way isn't supported for some reason.
I also thought that the combination of showDataTips and dataTipField property settings you have would work, but seems that's no good either. Check the archives; it's possible that's a known bug in the tree control. You may have to check out Tracy's suggestion of using an itemRenderer and setting the toolTip on the node itself. --- In [email protected], "Greg Morphis" <[EMAIL PROTECTED]> wrote: > > Hey Doug, thanks for the reply > That works great, and I think I found the snag.. itemRollOver doesnt fire > when I move from item to item..
