Wrong question. I would understand if you asked "what to use instead of drop-down list". If you have 200 values or so, the idea of drop-down list does not work well.

Agreed and it screams bad design if you are trying to get a user to select 1 thing in 200, at least in part because when was the last time anyone read a list of 200 let alone remembered enough of the items to pick the correct one by the time they were finished reading... I suggest the OP possibly (I'm guessing here given it's web based) should use multiple drop downs (2 or maybe 3) to break the options down into smaller categories and sub-categories, in much the same way as the CodeProject article submission page does.

Hope this helps (the OP),
Ed

The default implementation of dropdownlist in ASP.NET will allow the user to type and select the item based on the characters entered. However, 200 items maybe a bit too much. Perhaps you could consider a cascading dropdown[^]

"any idea"

Yes, don't use third party controls that remove built-in functionality or can't be extended.

Somebody has a google style dropdown. See Ajax ComboBox in ASP.NET[^]

Instead of using drop down, you can text box and in text key down you can search the required field by using JSON and Jquery.
