  InnerException: 

Style being used is defined as follows:

  <Style x:Key="LeftAlignedXamGridIntegerEditorStyle"  TargetType="{x:Type igEd:XamNumericEditor }">                           

        <Setter Property="VerticalAlignment" Value="Center"/>

        <Setter Property="FlowDirection" Value="LeftToRight"/>

        <Setter Property="HorizontalContentAlignment" Value="Left"/>                                

    </Style>

What should I do?

TIA.
