    You can also hide a custom action button when the UI component becomes read-only. Set the button's visible property to false in the onOptionChanged function. To get the button, use the getButton(name) method:

    jQuery
    index.js
    $(function() {
        $("#colorBoxContainer").dxColorBox({
            // ...
            buttons: [{
                name: "myCustomButton",
                // ...
            }],
            onOptionChanged: function(e) {
                if(e.name == "readOnly") {
                    const myButton = e.component.getButton("myCustomButton");
                    myButton.option("visible", !e.value); // Hide the button when readOnly: true
                }
            }
        });
    });
