Why checkbox checked mark appears with mirrored image in windows 8.1, when applying FlowDirection as RightToLeft. it is normally in other windows os.

<CheckBox HorizontalAlignment="Center" VerticalAlignment="Center" IsChecked="True" 
FlowDirection="RightToLeft">

回答1:

if you want this as same in other OS, edit the template and hard code as left to right for the Tick.

You could set your own style to the checkbox:

<Window x:Class="WpfApplication21.MainWindow"

</Window>

Although the look will be slightly different but you can either go with it or change the style as well.
