Textbox and button to search in dropdown list? I think you should redesign logic/application.

you said there is huge data in dropdownlist i assume you have at least 100 items in it. Why not to use autocomplete extender? The reasons are, dropdownlist with huge data won't make sense. And searching should not be for 'dropdownlist'.

agree.

Try this simple technique, using just basic html and javascript, no ajax needed either.

Use a Textbox, have all the items in your javascript in the page_load, and play with the data as you type the letters, the filtered results for the matching word will be displayed below the textbox, very fast. This is a pretty old article(asp.net 1.1 days), but this is exactly what you are looking for.
