ComboBox Events

[MasterRacker]

I was troubleshooting a problem on a form and seem to be seeing an unexpected behavior. It appears that the ComboBox SelectedValueChanged event fires even if you select the same item that was originally selected.

Is this really the case, and if so, why?

(This is only a minor annoyance, but it seems to me that this event should only go off when something different is chosen.)

if you don't like this then create a class that extends combobox.

Override the SelectedValueChanged and determine if the index actually changed. If it does then call base.OnSelectedValueChanged(e); otherwise, don't bother.

It's not worth that much to me. I was just wondering if someone knew why that happens. To me a "changed" event shuold only fire if something actually changed. I can see a clicking on the same item firing a "click" or "select" event, but not a "changed" event.

Like I said, in my app, this is a minor annoyance. I have plenty of more important things to stress about. ;-)
