New Post: Change color of spinner button for decimalupdown

Hi,

Your code works in Windows8. I believe you are not working with Windows8.
Try to add the following in file Xceed.Wpf.Toolkit/Themes/Generic/Buttons.xaml
in the "SpinnerButtonStyleKey"

<Setter Property="Background" Value="{DynamicResource {x:Static themes:ResourceKeys.ButtonNormalBackgroundKey}}" />
<Setter Property="BorderBrush" Value="{DynamicResource {x:Static themes:ResourceKeys.ButtonNormalOuterBorderKey}}" />

Tell me if it helps.
Thanks.
