I try to bind my XamComboEditor's DataSource of my xamDataGrid and the binding doesn't work.  The field is a lookup, where the user must pick a value from the combobox.  The list contains Description and the bound field is called DrugId.  DrugList.Model contains a Id and a Description.  Here's my code:

<igDP:UnboundField Label="{x:Static cow:HealthResources.Drug}" Row="1" Column="0" BindingMode="TwoWay" BindingPath="DrugId">

              <igDP:UnboundField.Settings>

                <igDP:FieldSettings  EditorType="{x:Type igEditors:XamComboEditor}" >

                  <igDP:FieldSettings.EditorStyle>

                    <Style TargetType="{x:Type igEditors:XamComboEditor}">

                      <Setter Property="ItemsSource" Value="{Binding DrugList.Model}" />

                      <Setter Property="DisplayMemberPath" Value="Description" />

                      <Setter Property="ValuePath" Value="Id" />

                    </Style>

                  </igDP:FieldSettings.EditorStyle>

                </igDP:FieldSettings>

              </igDP:UnboundField.Settings>

            </igDP:UnboundField>

This gives me the error in VS output window: BindingExpression path error: 'DrugList' property not found on 'object' ''TemplateDataRecord' (HashCode=3700058)'. BindingExpression:Path=DrugList.Model; DataItem='TemplateDataRecord' (HashCode=3700058); target element is 'XamComboEditor' (Name=''); target property is 'ItemsSource' (type 'IEnumerable')

A simple combobox like this show the items list correctly, so the problem lies only in the way I have to set the binding:

<ComboBox Width="100" DisplayMemberPath="Description" ItemsSource="{Binding DrugList.Model}" </ComboBox>

How should I set the binding to fill that xamComboEditor?
