ListBox SelectedValueChanged Event Anomaly!!!!

[giddy]

Hi ,

someone brought to my notice sometime ago that the
SelectedValueChanged and SelectedIndexChanged event acts slightly
wierd.

Firstly ,the events fire even if you click/select the currently
selected item.

And secondly ,they fire when one clicks the white space!!(which is
horribly peculiar)

This is what i mean:

(clicking on the space below the last item causes the event to fire!)

Heres the code:

Heres the full solution compiled and everything:

Thanks

Yes always..true.. its annoying... We have overridden and made our own
listbox, and suppress the even when we don't need it, by having a property
of prev selected item.. You could do that...

Any other ideas are welcome..!

hm. . ok that might work.

One problem is if you wanted to do something when the user clicks on a
*item* and not a whitespace. Maybe one could handle the click event.

Still i wonder whether Microsoft has fixed this in .NET 3.0 , or even
knows about it!
