I am trying to set the background color to a tabItemEx when it is selected or MouseOver using below style.

<Style x:Key="tabTabItem" TargetType="{x:Type TabItem}">
        <Setter Property="Background" Value="#FFE1E1E1" >
          
        </Setter>
       
        <Setter Property="Foreground" Value="#FF000000"></Setter>
        <Setter Property="Margin" Value="2,0,2,0"></Setter>
        <Setter Property="VerticalAlignment" Value="Stretch"/>
       
        <Style.Triggers>
            <Trigger Property="IsMouseOver" Value="True">
                <Setter Property="Foreground" Value="#FFFFFFFF"></Setter>
            </Trigger>
            <Trigger Property="IsSelected" Value="True">              
               <Setter Property="Foreground" Value="#FFFFFFFF"></Setter>
               <Setter Property="FontFamily" Value="Arial"/>
                <Setter Property="Background">
                   <Setter.Value>
                    <LinearGradientBrush EndPoint="0,1" StartPoint="0,0">
                       <GradientStop Color="#FFB14D71" Offset="0.125"/>
                       <GradientStop Color="#FF913E5C" Offset="0.789"/>
                    </LinearGradientBrush>
                   </Setter.Value>

But it is not setting any color. it is displaying default color only.

Am i doing ny thing wrong? Please suggest me the correct way.

                </Setter>
            </Trigger>
        </Style.Triggers>
    </Style>
