A colleague of mine is using a combobox extender in an ASP.NET project and has come across a strange issue with it.
When there's a lot (say 20 or more) items listed, then the displayed items go off the bottom of the screen and the scroll bar is shown. If there's a smaller number of items (say, 10) then the list is displayed without a scrollbar. Only 8 of the 10 items will be displayed, but the scrollbar is still hidden.
We have both had a look at the available properties of the combo box and not found anything that we think would affect this issue. Also, I have suggested that there could be something within the CSS of the page that "messes" with the displayed items... he says that removing all CSS file references doesn't make a difference.
Has anyone come accross anything like this before?
