回答済みWhen does ItemsControl.ItemContainerGenerator generate ListBox items?

    I have a ListBox that is initially Collapsed.  When a user clicks on a checkbox, the ListBox becomes Visible.  I want to programmatically select items the user had selected before when the ListBox is Loaded or becomes Visible.

    However, the ItemsContainerGenerator is returning null for this data items, container, unless the ListBox was not initially Collapsed.

    I have tried selecting the ListBox items programmatically within the Loaded and IsVisibleChanged event handlers but ItemsContainerGenerator is still returning null.

    Any other suggestions?

    TIA.
