Comboboxes with large datasets

Hello,

I have a 2 comboboxes within my call tracking application each of which contain large sets of data.
One contains 500 records the other about 3000 records. The initization of the combobox is very slow with this much data.

I tried to solve the issue by using the onChanging event so as they typed I'd query my database to return a smaller dataset
based on the first letter. This works okay, but sometimes the combobox does not return the onChanging event and they have to
click out of the combobox and then click it again to get it to work.

The users want autocomplete and autodrop so I have to stick with combobox instead of listbox which has paging.
How to handle large datasets with comboboxes and keep good performance?

Thanks,
William
