ComboBox Background Color WPF-CodePudding

I try to create a CustomControl ComboBox but i can´t change the Background color of the main ComboBox. I hope to creat a custom ComboBox with the same propertys of a normal ComboBox but with fix Colors.

Any Solution how can i change the Background Color of my custom ComboBox in the Generic.xaml?

Generic:

   <Style TargetType="{x:Type local:CustomComboBox}">
    <Setter Property="BorderBrush" Value="Blue" />
    <Setter Property="Background" Value="Yellow" />
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type ComboBox}">
                <Border Background="Green"
                        BorderBrush="Green"
                        BorderThickness="50"
                        >
                    <DockPanel >
                        <ComboBox Background="Gold" BorderBrush="Gold"/>
                    </DockPanel>
                </Border>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

To set the Backgroundcolor doesn´t work...

You Can easily modify the default Style, to do that follow the next steps:

Insert your ComboBox.

Right click on ComboBox (In Design Area).

Edit Template ==> Edit a copy

Change the color of ComboBox.Static.Backgroun by yours

<LinearGradientBrush x:Key="ComboBox.Static.Background" EndPoint="0,1" StartPoint="0,0"> <GradientStop Color="#FFF0F0F0" Offset="0.0"/> <GradientStop Color="#FFE5E5E5" Offset="1.0"/> </LinearGradientBrush>

Thanks for answering. Now i can change my color but i dont have a CustomControl. i think this is the full generic code but i dont have the class... :( Where can i get the full class of the ComboBox?

Generic:

    <Style TargetType="{x:Type local:CustomComboBox}">
    <Setter Property="BorderBrush" Value="Blue" />
    <Setter Property="Background" Value="Yellow" />
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type local:CustomComboBox}" >
                <Border Background="Green"
                        BorderBrush="Green"
                        BorderThickness="2">
                    <ComboBox Style="{DynamicResource IdxComboBoxStyle}"/>
                </Border>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

I insert my style now but i cant work with it. The propertys have no effect.
