I am using a dropdown datawindow which allows editing. When i am editing a correct value in it everything works fine. (i am using this datawindow to select a bank. bank_descr appears and bank_code is returned to the program ). However when i am giving a bank code that does not exist in the dropdown list i am not receiving any error indication. i know that i can check the whole situation thru itemchanged event. Is it possible to do it with some other way?
