I tried to change the default style for ListBox validation in my themes.xaml file but don't know how. I hope can help me
There is no need to use Themes.xaml
to override a default Style
in WPF. You can do it quite simply using an ordinary Style
in any Resources
section:
<Style TargetType="{x:Type ListBox}">
<Setter Property="OverridesDefaultStyle" Value="True" />
<!-- Your Style Setters here -->
</Style>
