New Post: checkcombobox grouping

Hi,

First, you are setting the CheckComboBox.ItemsSource property in XAML and in code-behind. One will overwrite the other.

To display the wanted property of the SelectedItems from the CheckComboBox, do not define an ItemTemplate. Instead, set the DisplayMemberPath property on the CheckComboBox :

DisplayMemberPath="WD"

This will display the "WD" property both as the available items and the SelectedItems in the CheckComboBox.
