SAM_FieldEdit is sent to a combo box, data field, multiline text field, table window, or table window column when you change a window's value and then move the focus away from that window. For example, if you enter a value into a data field, then press the TAB key or click the mouse to move to another field, a SAM_FieldEdit message is sent to the data field. The SAM_FieldEdit message is different from the SAM_AnyEdit message. A SAM_AnyEdit message is sent for every keystroke, while a SAM_FieldEdit message is sent only when you attempt to leave a window whose value you changed. Use SAM_Validate for field validation. SAM_Validate supersedes SAM_FieldEdit.
