Short answer: Yes.
The asp:listbox renders as an HTML SELECT element.
Adding the html attribute "title" to the rendered SELECT will give you
a tooltip
for VB
<listbox>.Attributes.Add("title", "Title goes here")
- and you don't even need javascript!
HOWEVER (and this is probably your problem) IE does not implement title
for the SELECT element.
If you really, really, realy need to fake it, you can use the
mouseover/ mouseout events to show/hide a seperate "tooltip" HTML
element.
Don't forget the IE windowed controls z-index bug!
