I have a listbox with three items named as

-sudhakar
-Amalraj
-Suresh

Above the listbox,I placed an textbox for search, whenever the user type in the textbox then the listbox should display only the entered text matching with item in listbox.

I mean if i type the letter "S" then the listbox should display only "sudhakar" and "Suresh". similar i fi type "Sud",the listbox should display only "sudhakar".

Please help me to sort out
