New Post: CheckComboBox selectedItems

Hi,

1. Yes, the CheckComboBox.ItemSelectionChanged event is currently only raised when the drop-down has been opened. It will be fixed in v3.4 along with the Command property raising.
   
2. Yes a workaround can be
   a) add a handler for CheckComboBox.SelectedItems.CollectionChanged (if the CheckComboBox.SelectedItemsOverride will no longer be modified) :
   

( ( ObservableCollection<UserGroupType> )UserGroupsTypesCheckedComboBox.SelectedItems ).CollectionChanged += MainWindow_CollectionChanged

b) add a handler of CollectionChanged for your bound variable to CheckComboBox.SelectedItemsOverride (if you are modifying the CheckComboBox.SelectedItems via your bound variable to CheckComboBox.SelectedItemsOverride ) :

tempSelectedUserGroupTypes.CollectionChanged += TempSelectedUserGroupTypes_CollectionChanged;
