Hello,

I was wondering what is the difference between the selectedIndexChanged
and the selectionChangeComitted events of ComboBoxes.

Thanks in advance,

I'm pretty sure SelectionChangeCommitted is only raised by UI occurances,
i.e. actually using the ComboBox and moving the highlight.
SelectedIndexChanged is raised a whole lot, including databinding, any time
the SelectedIndex property is changed by either the UI or code.

Best Regards,

Andy

Anyways, it doesn't work correctly with .NET 1.0 and 1.1. I don't know if
they fixed it for 2.0

See that thread for some of the issues with that event

I had been trying to nail down those strange behaviors for quite a while, as
I'm a heavy keyboard user (way more efficient at times). And you just led
me right to them.

Thanks!

Best Regards,
