Kevin,

I am populating some textboxes with data that corresponds to the item that is currently selected in the list box. So, as the user moves from item to item, the contents of the textboxes change.

I may modify my code so that the tag of the listbox contains a string representation of the currently selected index. And then, as you suggested, on the click event, I can test the new listindex vs. the index stored in the tag...if they are different, I can fire the IC. If this works I may add a property to my base listbox class to carry this value.

what do you think?

Phil
