Type ahead suggestion show in listbox while typing in textbox

[Yashwant]

I have textbox to enter and below that two listbox in between having buttons to trabsfer items from one to another listbox as shown in attached image.

Now I want functionality where while typing in textbox I will fetch data from DB from show suggestions in left listbox all dynamic.

i.e. 

lets say If i type 'Tes' in textbox, system will fetch records which contains entered text and show suggestions in left listbox. Now if I continue to write further 'Testdata' or remove any character already enetered 'Te', the below left listbox should be updated accordingly dynamically.

 

Thanks in advacnce and any asap help is appreciated.
