Hi,

I am writting the control Template of HeaderPrefixArea as below:

<Style TargetType="{x:Type igDP:HeaderPrefixArea}">
<Setter Property="Visibility" Value="Visible"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type igDP:HeaderPrefixArea}">

<Grid>
<ContentPresenter Content="{TemplateBinding Content}" ContentTemplate="{TemplateBinding ContentTemplate}" VerticalAlignment="{TemplateBinding Control.VerticalContentAlignment}" HorizontalAlignment="{TemplateBinding Control.HorizontalContentAlignment}" />
</Grid>

</ControlTemplate>
</Setter.Value>
</Setter></Style>

Now if I set HeaderPrefixAreaDisplayMode="FieldChooserButton", it is not appeared at all in the prefix area.

<eclp:EclpGrid.FieldLayoutSettings>
<igDP:FieldLayoutSettings SelectionTypeRecord="Single" AutoGenerateFields="False" HighlightAlternateRecords="True" HeaderPrefixAreaDisplayMode="FieldChooserButton" >
</igDP:FieldLayoutSettings>
</eclp:EclpGrid.FieldLayoutSettings>
<eclp:EclpGrid.FieldLayouts>

If I comment the Style, it works.
Kindly suggest.
