What exactly is your problem ? Is that your test() not getting called or on selection of any item in dropdown list, you want the test() to fire?

Add some more description by selecting 'Improve question' option.

If you want test() to be called on dropdown click/selection even you need to add event handler to dropdown list, not for textbox as u added.

C#

ListBox1.Attributes.Add("onchange", "javascript::test();")
