The ASP.NET DropDownList and the AjaxControlToolkit ComboBox are both very similar. In fact, the AjaxControlToolkit's ComboBox derives from the same base class as the ASP.NET DropDownList. The ASP.NET AJAX site gives a good summary of the differences and similarities between the two controls:

Working with a ComboBox in code is also a lot like working with a DropDownList. It has all of the same properties and events as a DropDownList, with a few additional ComboBox-specific properties and events. Firstly, it can be configured to either prevent or allow user-typed text that does not match an item in the list. When user-typed text does match an item in the list, the ComboBox can also be configured to auto-complete the text based on the first matched item in the list, to show the list and highlight the first matched item, or to do both simultaneously. When user-typed text does not match an item in the list, the ComboBox raises ItemInserting and ItemInserted events which can be handled during postback. Other than these special behaviors, the ComboBox behaves essentially like a DropDownList.

In summary, a ComboBox is primarily a DropDownList that allows you to type text into the control in addition to simply using the dropdown arrow to select an existing item from the list.
