How can I implement incremental search on a listbox?

Question

I want to implement incremental search on a list of key-value pairs, bound to a Listbox.

If I had three values (AAB, AAC, AAD), then a user should be able to select

If I'm interpreting your question correctly, it seems like you want users to be able to start typing and have suggestions made.

You could use a ComboBox (instead of a ListBox):

1. Set the DataSource to your list of KeyValuePairs,
2. Set the ValueMember to "Key" and the DisplayMember to "Value",
3. Set AutoCompleteMode to SuggestAppend, and
4. Set AutoCompleteSource to ListItems
