Question

I’m trying to add OuterGlowBitmapEffect effect to TextBox when Mouse hovers it.
I use triggers. Here is some code:

<TextBox Height="23" HorizontalAlignment="Left" Style="{DynamicResource TextBoxStyle}" Margin="12,283,0,0" Name="textBox1" VerticalAlignment="Top" Width="147" Text="" />

<Style x:Key="TextBoxStyle" TargetType="{x:Type TextBox}">
    <Setter Property="FontSize" Value="14" />
    <Style.Triggers>
        <Trigger Property="IsMouseOver" Value="True">
            <Setter Property="BitmapEffect">
                <Setter.Value>
                    <OuterGlowBitmapEffect GlowColor="Red" GlowSize="10"/>
                </Setter.Value>
            </Setter>
        </Trigger>
    </Style.Triggers>
</Style>

But it’s not working. What i missed?

From the documentation of BitmapEffect:

[ObsoleteAttribute(“BitmapEffects are deprecated and no longer function. Consider using Effects where appropriate instead.”)]

You can simulate a glow using the Effect property with an instance of DropShadowEffect.
