How to add lookup for the unbound textbox?

I tried with edt relationship and assigned that edt for unbound textbox. But this method is not working. Please guide me.

Thanks,
Hari

You can use EDT relation - unfortunately I don’t have enough information to say what you did wrong.

You can override lookup() method of the control.

Or you can create a lookup form and use it in the FormHelp property.

Check the documentation (Lookup Forms Overview) for details.
