title: Searchable dropdown in windows form?
body: <p>I have an application that's a front end to another server-side application. Users of the app can make a "rule" in the application and assign it a "justification." The problem is that there are around 4,000 justifications. Assigning a justification is a requirement. Currently I have it in a dropdown, but I have had many feature request for there to be a way to search this dropdown, or type something in to narrow the search field. Any suggestions on how I could achieve this? Never seen anything like it in a windows form. Closest thing I can think of is Google autocomplete.</p>
