Hi, I am using a dropdown to populate a textbox. But if preferred value is not present in dropdown then user directaly enter value in that textbox.

If user selects value from dropdown first and then he don't want that value and he types another text in that textbox then at this time the dropdown should be set to index 0 as user is typing another value.

I used textchanged event of textbox but it is not working. Can anyone tell me how to write javascript for this? Thanks in advance.
