I am writing a program which includes a folder and file browser controls. While the program is running, the user can create or delete files at the folders shown at my program. I am wondering at which event i should refresh my controls to reflect this changes. Currently i do that on Form.Activate event, but it dosn't work as Windows Explorer for example, which refreshes when the change is made and not when activated.
I guess it is something essential. Thanks beforehand.
