what is the suggested place to call savesettings?

is there anything like an onsettingschanged or onunload event that i could hook to persist the controls settings?

C#

the thing is, that i don't want to do it in the form but in the control itself. i made a custom user control in c# that contains the active-x component, but there is no such thing as an unload handler for controls.

i overloaded dispose for this purpose, but it seems a bit too late as you never know in which order components are disposed and hence you might reference already disposed components.
