A DropDownList doesn't allow you to input something in it. A combobox does.

What you are tying to do is something like an autocomplete textbox. There are many ways to implement it based on your preference. Here are couple of them:

If you really want a multi-column autocomplete, then you may need to craft your own custom control or use a thrid party control that provides the feature that you have. For example: OBOUT - ASP.NET ComboBox - Grid-Like Multi-Columns[^]

Solution 2

Try this...

$(function () {
$('[id*=DropDownList1]').multiselect({
enableFiltering: true
});
});
