Hi,
For Part 1), I tried your code (without the commented lines) and it worked fine : the CheckComboBox starts with item selected. Using "SelectedItemsOverride" and/or "SelectedValue " will check the 2 first entries in the CheckComboBox, which are "abc" and "def". I tried activating the selection it in the constructor of the Window and/or in the Loaded callback of the Window and it still worked. I tried this selection in Toolkit v1.9 and v2.0 with success. It has to be something else, maybe in xaml ?
For Part 2) I reproduce the bug. You are doing a For loop on SelectedItemsTotal. When adding, it will work. When you select an item from CheckComboBox, SelectedItemsTotal will go from 0 to 1 and the read and addition will be done to CheckListBox. When selecting a 2nd item from CheckComboBox, SelectedItemsTotal will go from 1 to 2 and the read and addition will be done on the 2nd loop to CheckListBox.
But when removing an item from CheckComboBox, if you have 2 selectedItems ("abc" and "def") and you remove "def", CheckComboBox.SelectedItems will contain "abc". But your "selectedCostCenter[ j ]" will contain "abc" while "e.Item" will contain "def" (the removedItem). Since it's not equal, no removing will be done in CheckListBox.
You should find another way of detecting the removedItem. I confirm that the line :
