I made a web page with a listbox control displaying a long list of iterms for user to choose.
To make it easier for user to select an item from the list box, I want to make it ideally like this: when user quickly type in several characters like "ABC", the first item in the list box start with "ABC" will be highlighted (just like how our desktop windows explorer works).
Considering carefully it doesn't seem easy, but there may still be a way to implement:
1. need to keep track of time period between two key-ins to decide whether they should be considered as one search input.
2. cannot use post back on key stroke event because this way will neither be user friendly, nor be able to keep track of a sequence of keys due the web page refreshing.
Can you let me know if you have a way to do that?
