Is it Possible to Write in a DropdownList or listbox?
<p><strong>work on Asp.Net C# vs08.</strong>
I was wondering if it is possible to write in a dropdownlist or listbox  such that if somebody does not want to select from the dropdownlist or listbox, he/she can type the value and if the value exist in the dropdownlist/listbox, it autofills.  The person may then select it.  If this is not possible in ASP.NET, would anybody know of another control that can be used for the same purpose and how?</p>

<p><strong>what I really need is how to allow the writting on the DropDownList, please someone help me!. Thank you very much.</strong></p>
