Hi,
   I am trying to display a selected value in combobox which is a field of xamdatagrid in hierarichal Visual Tree and the Value I want to display in combobox as selected value is from hierarichal data which is binded with Data Grid. e.g.

Class ABC
{
 A {get;set;}
 B {get;set;}
 C {get;set;}
}

Class DataGridDataItem
{
  X {get;set;}
  Y {get;set;}
         BindingList ABC {get;set;}

}

Class PresenterofDataGrid
{
 BindnigList<DataGridDataItem> GridSource {get;set;}
 
}

and in Xaml I am doing in this Way..

<igDP:FieldLayout Key="0" >
                        <igDP:Field Name="X" Label="X"/>
                        <igDP:Field Name="Y" Label="Y" />
                        <igDP:Field Name="ABC" Label="ABC" />
</igDP:FieldLayout Key="0" >

<igDP:FieldLayout Key="1" >
                        <igDP:UnboundField Label="ABC" Name="Tenors"  DataType="{x:Type NS:ABC}" >
                            <igDP:Field.Settings>
                                <igDP:FieldSettings EditorType="{x:Type igEditors:XamComboEditor}">
                                    <igDP:FieldSettings.EditorStyle>
                                        <Style TargetType="{x:Type igEditors:XamComboEditor}">
                                            <Setter Property="SelectedItem" Value="{Binding Path=????}"/>
                                            <Setter Property="DisplayMemberPath" Value="A"/>
                                            <Setter Property="ItemsProvider" Value="{Binding Source={StaticResource MySource} }" />
                                        </Style>
                                    </igDP:FieldSettings.EditorStyle>
                                </igDP:FieldSettings>
                            </igDP:Field.Settings>
                        </igDP:UnboundField>
