I have a Button and its Style:
<Button Name="MyBtn" Style="{StaticResource ButtonEnabledStyle}"
IsEnabled="False" Opacity="1" />
<Style x:Key="ButtonEnabledStyle" TargetType="Button">
<Style.Triggers>
<Trigger Property="IsEnabled" Value="True" >
<Setter Property="Opacity" Value="0.1" />
</Trigger>
</Style.Triggers>
</Style>
But when I enable the Button (MyBtn.IsEnabled = true) it does not change its Opacity. Why? How can I solve this problem? Thanks.
A local value set on the element (
Opacity="1"in your code) will always take precedence over a style or style trigger value. Please have a look at Dependency Property Setting Precedence List.An easy fix is to set the default value on the style instead:
