Textbox search with dropdown results

I (think I) want to develop a custom control for my program in VB .net where I type into a textbox and simple search results will then be displayed underneath it (from a predefined set of items). Like auto suggest in google search.

I believe the combobox does something similar to this but I think it only works on prefixes.

At the moment I have a separate search form from which I use to filter a lot of possibilities and then use drag-and-drop to get the desired item into a TextBox.

So ideally I want to combine this with a TextBox into which one can start typing at which point some results will be displayed and a user can select the item they want. (Say, an item from a list of products)

Is t开发者_如何学JAVAhis a good idea? How can I go about it best? Does it already exist?

It has been bugging me for AGES!

Help appreciated!

This functionality is supported out of the box in Windows Forms 2.0 and beyond. Check out the AutoCompleteSource and AutoCompleteMode properties of both the TextBox and ComboBox windows forms objects.
