I have below codes working fine with dropdown. but auto complete does not work.
It shows 'internal object error' which I don't know what it is. Anyone can help? You can copy/paste the code to your visual studio and it will show when you type something inside of the textbox.

Out of my desk, I don't have VS currently, if you can publish your code to internet, I can help.
Which results do get when calling the web method directly? Could you post it?
