Hello.

There are grid below. I need to set one margin of header text in first and last colmns and another margin of header text in others columns. I tried to do
it by implementing DataTrigger in LabelPresenterStyle, but it doesn`t work. How can I do it?

<Style TargetType="{x:Type igDP:LabelPresenter}" BasedOn="{StaticResource LabelPresenterStyle}" >

<Setter Property="BorderThickness" Value="1,0,1,0"/>

<Setter Property="ContentTemplate">

<DataTemplate>
<TextBlock Name="textBlock" Margin="8,0,8,0" Text="{TemplateBinding Content}"/>

<DataTrigger Binding="{Binding Path=Field, RelativeSource={RelativeSource AncestorType={x:Type igDP:LabelPresenter}}}" Value="Field: OrderNumber">
<Setter TargetName="textBlock" Property="TextBlock.Margin" Value="16,0,16,0"/>
</DataTrigger>
<DataTrigger Binding="{Binding Path=Field, RelativeSource={RelativeSource AncestorType={x:Type igDP:LabelPresenter}}}" Value="Field: Comment">

</DataTrigger>
