Geeky, You really thought that I didn't know what you said?!!! I am not a kid. My problem is I need to add an element to a combobox's valuelist which is unbound. It can be done only in design mode right? otherwise it will be added only temporarily. Otherwise tell me a way to add a element in a combobox's valuelist on it's notinlist event. Please don't suggest to change it to a bound control.
