How to modify a setter from code behind in WPF

I tried to modify a background property alone in a Style from code behind for some internal purpose in my WPF application, below error thrown when try to add a new setter to the style that we used

After a 'SetterBase' is in use (sealed), it cannot be modified.

How can i resolve this?

Thanks in advance

if you have something along the lines of:

<Setter Property="Button.Background" Value="Red" />

this can be replaced using the code behind. In C#, that would look like this:

var setter = new Setter
{
  Property = Button.BackgroundProperty,
  Value = "red",
};

Or, using bindings:

Value = new Binding("BackgoundColour"),

where BackgroundColour is a variable.

I am not sure if this works when the base is sealed, but try it.
