I am able to clear the selection of a list programmatically, by setting: myList.selectedIndex = -1
but setting the selection to a specific index is not working. The previous highlighting goes away, and based on watching the list in the debugger, the property does seem to change, but the new selection is not highlighted. Do I need to invalidate something in addition to just setting the property? In case it matters - the list is inside a component which is repeated in a Repeater. - there is an item renderer - the data provider is a custom IList implementation. But all other use cases (user click, up-down arrows, clearing selection programmatically) work perfectly. Thanks.
