Hello Frank,

Could you please elaborate a little bit more on the issues which you are facing. I prepared a small sample based on your code and on my side when I select a value I could get it from the SelectedItems collection. Also please note that the CheckBox are enabled only in edit mode, otherwise they are disabled. If you want to enable them then you have to use a TemplateColumn with a CheckBox control as an ItemTemplate.
