Hi again,

                        <dataPresenter:UnboundField.Settings>
                            <dataPresenter:FieldSettings EditorType="{x:Type igEditors:XamTextEditor}">
                                <dataPresenter:FieldSettings.EditorStyle>
                                    <!--My changes on the style begin-->
                                    <Style TargetType="{x:Type igEditors:XamTextEditor}">
                                        <Setter Property="EditTemplate">
                                            <Setter.Value>
                                                <ControlTemplate TargetType="{x:Type igEditors:XamTextEditor}">
                                                    <igEditors:XamComboEditor ItemsSource="{Binding DataItem.Hobits}"                                                                           
                                                                          SelectedItem="{Binding DataItem.Hobit}"
                                                                          Padding="1"/>
                                                </ControlTemplate>
                                            </Setter.Value>
                                        </Setter>
                                        <Setter Property="Background"
                                            Value="{Binding Path=Background,RelativeSource={RelativeSource Mode=FindAncestor,AncestorType={x:Type dataPresenter:CellValuePresenter}}}"/>
                                        <Setter Property="BorderThickness" Value="0"/>
                                    </Style>
                                    <!--My changes on the style end-->
                                </dataPresenter:FieldSettings.EditorStyle>
                            </dataPresenter:FieldSettings>
                        </dataPresenter:UnboundField.Settings>
                    </dataPresenter:UnboundField>

Hello,

I modified the sample further, so now it works as you want. Basically I used the Utilities class to get the XamComboEditor since the CellValuePresenter's Editor is XamTextEditor now. Please let me know if this helps you or you have further questions on this matter.
 
Looking forward for your reply.

Thank you for the quick reply, it works in the sample project and I will try to adapt it into our real application to see if it works.

hi again,

I found a new problem and I didn't find the way to fix it.

here is the problem:

When I type any key, if the combo have the item, it will automatically set the item as selected, you will see it in your sample.

Do you have any idea to fix it?

Thank you!
