Some of our comboboxes have thousands of items. The end result is when the user clicks the drop down to expand the list of items, there is a very noticeable delay. I've tried different features like load on demand and type ahead, but they don't all work for every situation.

For example, for combo boxes that have a selected item, I'm not sure I can use load on demand. If, say, I set the combo box to load 100 at a time, but the selected item is number 300, will it cause an exception?

And type ahead helps, but the user still might click the drop down.

Any help?
