Hi everyone I was helping someone bind multiple property values to one column and learned some new things. Then I applied what I learned to ComboBoxes. and found a new way to Bind ComboBox.ItemsSource at runtime related to the current row.

                            <xcd:CellEditor>
                                <xcd:CellEditor.EditTemplate>
                                    <DataTemplate>
                                        <ComboBox
                                            DataContext="{Binding RelativeSource={RelativeSource AncestorType=xcd:DataRow}, Path=DataContext}"
                                            ItemsSource="{Binding Employee.JobCodes}"
                                            SelectedItem="{xcd:CellEditorBinding}"
                                            IsEditable="True"
                                            DisplayMemberPath="Jc"/>
                                    </DataTemplate>
                                </xcd:CellEditor.EditTemplate>
                            </xcd:CellEditor>

The DataRow Context is your data Item(business object)

ItemsSource="{Binding Employee.JobCodes}" //Employee is a property  on my business object and JobCodes is an IEnumerable on Employee

  DisplayMemberPath="Jc" Jc is a property on the JobCode object

Just thought I would share as there are lots of ComboBox Posts
