Commented Issue: ListPicker allows selection of new item after page transition [10770]

When the page is transitioning out after a selection, it is possible to click on another item in the list, and that one ends up as selected. Surely the control should be disabled after the transition has begun.

The fix is to modify ClosePickerPage thus:

private void ClosePickerPage()
{
IsOpen = false;
// AAW: disable picker on exit.
Picker.IsEnabled = false;
}
