Lost Gray On IsEnabled False

Question

Once I set the TextBlock Foreground Property then I lost the gray on IsEnable=False on buttons and also lost the gray on ToolTip.

How can I set a the style for TextBlock foreground and not effect the IsEnable=False and ToolTip?

<Style TargetType="TextBlock">
    <Setter Property="FontFamily" Value="Segoe UI Semilight" />
    <Setter Property="FontSize" Value="11" />
    <Setter Property="Margin" Value="4,1,0,1" />
    <Setter Property="Foreground" Value="{StaticResource  BrushDarkDarkBlue}" />
</Style>

Just place your Foreground setter in a Trigger that will only set the value if the IsEnabled property value is true:

<Style TargetType="TextBlock">
    <Setter Property="FontFamily" Value="Segoe UI Semilight" />
    <Setter Property="FontSize" Value="11" />
    <Setter Property="Margin" Value="4,1,0,1" />
    <Style.Triggers>
        <Trigger Property="IsEnabled" Value="True">
            <Setter Property="Foreground" Value="{StaticResource BrushDarkDarkBlue}" />
        </Trigger>
    </Style.Triggers>
</Style>

When IsEnabled turns to false, the default (template / style) value will be set keeping this "graying out" effect.
