To change window properties by event handler - wpf

Question

I need to change properties (ex background color) of Window based on Event handler.
we can easily do this to any controls inside window by writing it in windows.Resources as shown below.
<Window x:Class="WpfApplication8.Window1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:local="clr-namespace:WpfApplication8"
mc:Ignorable="d"
>
<Window.Resources>
<ResourceDictionary>
<Style TargetType="{x:Type Button}" >
<EventSetter Event="SizeChanged" Handler="OnbuttonLoaded"/>
</Style>
</ResourceDictionary>
</Window.Resources>
<StackPanel>
<Button x:Name="Button1" Width="100" Height="20"/>
<Button Width="100" Height="20"/>
<Button Width="100" Height="20"/>
<Button Width="100" Height="20"/>
<Button Width="100" Height="20"/>
</StackPanel>
</window>
xaml.cs is as follows
private void OnbuttonLoaded(object sender, RoutedEventArgs e)
{
Button1.Background = Brushes.Red;
}
But when I have to change background color of window itself when it's SizeChanged. what can i do???
Please do help.... Thank you

And why not to use Window Style property?
<Window.Style>
<Style TargetType="{x:Type Window}">
<EventSetter Event="SizeChanged" Handler="EventSetter_OnHandler"/>
</Style>
</Window.Style>
If you need some global solution, put it in App Resources.
