Why is this happening and how can we avoid this?

Hi rishi_invar,

We’ve taken a look at this here and there appears to be some strange things happening in the WPF Framework
when it comes to resolving inherited property settings (TextBlock.Foreground in this case). 
The style you have set up seems perfectly reasonable but that is not having the desired effect due to this
WPF framework weirdness.

What you can do to workaround this issue is to use the solution suggested by Joe Modica and Andrew Smith.
Special thanks to both of them for the suggested solution. 

<Style TargetType="{x:Type igDP:CellValuePresenter}">
    <Style.Triggers>
       <DataTrigger Binding="{Binding Path=IsMouseOver, RelativeSource={RelativeSource AncestorType={x:Type igDP:DataRecordCellArea}}}" Value="True">
          <Setter Property="ForegroundStyle">
             <Setter.Value>
                <Style>
                   <Setter Property="TextBlock.Foreground" Value="Red"/>
                </Style>
             </Setter.Value>
          </Setter>
      </DataTrigger>
   </Style.Triggers>
</Style>

The attached TextBlockForegroundPropertyIssueSolution sample application contains the full solution implementation.

 Hi,

 I have tried implementing this,and does kind of work, except the text color is not changed to Red but the font size and weight is updated. Is there something i am missing, here is my code:

<Window x:Class="WpfApplication1.Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:igDP="http://infragistics.com/DataPresenter"
    Title="Window1" Height="336" Width="619">
    <Grid>
        <igDP:XamDataGrid BindToSampleData="True">
            <igDP:XamDataGrid.Resources>
                <Style TargetType="{x:Type igDP:DataRecordCellArea}">

                    <Setter Property="ForegroundHoverStyle">
                       <Setter.Value>
                            <Style>
                                <Setter Property="TextBlock.FontFamily" Value="Arial" />
                                <Setter Property="TextBlock.FontSize" Value="15" />
                                <Setter Property="TextBlock.FontWeight" Value="Bold"/>
                                <Setter Property="TextBlock.Foreground" Value="Red"/>
                            </Style>
                        </Setter.Value>
                    </Setter>
                    <Setter Property="BackgroundHover">
                        <Setter.Value>
                            <LinearGradientBrush EndPoint="0,1" StartPoint="0,0">
                                <GradientStop Color="#FF2225FF" Offset="0"/>
                                <GradientStop Color="#FFB9D8FF" Offset="1"/>
                            </LinearGradientBrush>
                        </Setter.Value>
                    </Setter>
                    <Setter Property="BorderHoverBrush" Value="#FF000000"/>
                </Style>
            </igDP:XamDataGrid.Resources>
        </igDP:XamDataGrid>
    </Grid>
</Window>
