Textbox Autocomplete with Atlas/Ajax Parameter Names
I won't bore you with the complete Textbox Autocomplete example. One interesting thing that I found out thanks to Michael and Wilco is that the method that you call to get the autocomplete string array must have the parameter names as prefixText and count. If you don't do this, it doesn't work.
public
String[] TextBoxAutoComplete(string prefixText, int count) // Seems to be a problem if the names are not prefixText and count.
