Selecting an item in comboBox by typing

I have a combobox that has hundreds item in it. User must be able to type in text into the combobox . While the user is typing the text, the item that starting with the typed value must be selected. The user must be able to continue typing. ComboBox DropDownStyle is DropDownList

Eg: While selecting a name in comboBox by typing, it only allows one letter. So if I type "A" it will jump to the first name starting with "A". then type "s", it will not jump to the first item starting with "As", but to the first item starting with "s".

I'm using Windows Forms.
