I have created a style to rotate some of the columns and display them verically within XamDataGrid. This works fine but when i apply this style to columns, the columns are displayed vertically in the field chooser as well. I tried creating a seperate style for field chooser which i have given below but the column header is still getting displayed vertically in field chooser. Can you please let me know how to solve this problem? 

----Vertical Header----

 <Style x:Key="VerticalHeader" TargetType="{x:Type controls:LabelPresenter}">
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="controls:LabelPresenter">
                    <Border BorderBrush="{StaticResource WarmGrey_74}" Background="{StaticResource WarmGrey_74}">
                        <TextBlock Foreground="{StaticResource NptBlue_DarkText}" FontWeight="Bold"
                                   VerticalAlignment="Center" HorizontalAlignment="Left" TextAlignment="Center">
                        <ContentPresenter>
                            <ContentPresenter.LayoutTransform>
                                <RotateTransform Angle="-90" />
                            </ContentPresenter.LayoutTransform>
                        </ContentPresenter>
                        </TextBlock>
                    </Border>
                </ControlTemplate>
            </Setter.Value>           
        </Setter>
    </Style>

----Field chooser----

 <Style x:Key="{x:Type controls:FieldChooser}" TargetType="{x:Type controls:FieldChooser}">
        <Style.Resources>
            <!--FieldChooserEntry represents a field in the field chooser. This data template shows
         the checkbox inside the label presenter instead of the default which is show it left of
         the label presenter.-->
