I would like to get rid of record hover appearance. I created a style for DataRecordCellArea with:

BackgroundHover = Transparent   -  this works

and

ForegroundHoverStyle = {x:Null}   -   this doesn't work. Foreground is still black when when record is hovered.

Here is full xaml:

<idp:XamDataGrid x:Name="HistoryGrid" x:FieldModifier="private" Theme="Office2k7Blue" GroupByAreaLocation="None"
DataSource="{Binding Path=History}">
<idp:XamDataGrid.Resources>
<Style TargetType="idp:DataRecordCellArea">
<Setter Property="Background" Value="{Binding Path=DataItem.BackgroundColor}"/>
<Setter Property="Foreground" Value="{Binding Path=DataItem.ForegroundColor}"/>
<Setter Property="BackgroundHover" Value="Transparent"/>
<Setter Property="ForegroundHoverStyle" Value="{x:Null}"/>
</Style>
<Style TargetType="idp:CellValuePresenter">
<Style.Triggers>
<DataTrigger Binding="{Binding Path=IsSelected, RelativeSource={RelativeSource AncestorType={x:Type idp:DataRecordCellArea}}}" Value="True">
<Setter Property="ForegroundStyle">
<Setter.Value>
<Style>
<Setter Property="TextBlock.Foreground" Value="White"/>
</Style>
</Setter.Value>
</Setter>
</DataTrigger>
</Style.Triggers>
</Style>
</idp:XamDataGrid.Resources>
<idp:XamDataGrid.FieldLayoutSettings>
