How to change disabled background color of TextBox in WPF

I've seen the following thread which is related to my question:

WPF ComboBox: background color when disabled

The above deals with changing the Content Template for a ComboBox. I am working with WPF, am somewhat new to Styles and Templates, and I want to change the dull gray background color of a disabled TextBox to some other color. We use TextBoxes frequently in our application and we find the default color settings difficult to read.

I've crafted the following solution attempt. But of course, it does not work. Can someone give me an opinion on why?

You can use the below snippet :

Instead of checking for IsEnable property, use IsReadonly property of TextBox control.

<Style TargetType="{x:Type TextBox}">
    <Setter Property="Background" Value="LightSkyBlue" />
    <Style.Triggers>
        <Trigger Property="IsReadOnly" Value="True">
            <Setter Property="Background" Value="Red" />
        </Trigger>
    </Style.Triggers>
</Style>

If You need to apply it for all the textbox controls, use the above code. For specific textbox, just set the key and apply the style to that Textbox.

Try to avoid redefining control templates where you can. They tend to add a lot of code overhead and can become difficult to maintain over time.

I would use the following code in the Loaded event:

ClassicBorderDecorator o = VisualTreeHelper.GetChild(this.textBox1, 0) as ClassicBorderDecorator;
if (o != null)
{
    o.Background = new SolidColorBrush(Colors.Transparent);
}
