show only the matched search pattern items in the dropdown ajaxToolkit:ListSearchExtender

Question

I have a dropdown where I've used ajaxToolkit:ListSearchExtender. The dropdown shows all the values of the list when I insert some text in the search pattern. I want to display only those values in the dropdown that matches the search pattern.

<ajaxToolkit:ListSearchExtender ID="toolkit_srch_address" runat="server" 
    TargetControlID="listBoxAddress"
    PromptText="SEARCH ADDRESS" 
    PromptPosition="Top" QueryPattern="Contains"
    IsSorted="true">
</ajaxToolkit:ListSearchExtender>

Suppose I've a dropdown list ::

apple
aloha
alpasian
appyan
banana
bacci
barsa
brittanica
bryan
cactus
caccy

Suppose I search for pattern "ac" then in the list bacci, cactus, caccy should show.

How can I do this, is this possible?

No. You'd rather use AutoComplete extender, that is designed specifically for that task.
