I am creating a dynamic context menu for a XamDataGrid.  I need to know what column the cell they are right clicking on is in.  Here is Xaml And Code Behind...

 <igDP:XamDataGrid  x:Name="XamDataGrid1"

                                   DataSource="{Binding Model.QueryResults}"

                                   Background="Transparent"

                                   Theme="Office2k7Black">

                    <igDP:XamDataGrid.Resources>

                        <Style TargetType="{x:Type igDP:DataRecordCellArea}"  >

                            <EventSetter Event="ContextMenu.ContextMenuOpening" Handler="cm_ContextMenuOpening"></EventSetter>

                            <Setter Property="ContextMenu">

                                <Setter.Value>

                                    <StaticResourceExtension ResourceKey="cmenu"></StaticResourceExtension>

                                </Setter.Value>

                            </Setter>

                        </Style>

                    </igDP:XamDataGrid.Resources>

                    <igDP:XamDataGrid.FieldSettings>

                        <igDP:FieldSettings AllowEdit="False" />

                    </igDP:XamDataGrid.FieldSettings>

                    <igDP:XamDataGrid.FieldLayoutSettings>

                        <igDP:FieldLayoutSettings HighlightAlternateRecords="True"/>

                    </igDP:XamDataGrid.FieldLayoutSettings>

                </igDP:XamDataGrid>

 CODE BEHIND:

void cm_ContextMenuOpening(object sender, ContextMenuEventArgs e)

        {

            DataRecordCellArea item = sender as DataRecordCellArea;

            DataRecord dataRecord = item.Record;

            ContextMenu cm = item.ContextMenu;

            cm.Items.Clear();
