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

    jQuery
    index.js
    $(function() {
        $("#numberBoxContainer").dxNumberBox({
            // ...
            buttons: [{

            onOptionChanged: function(e) {
                if(e.name == "readOnly") {
                    var myButton = e.component.getButton("myCustomButton");
                    myButton.option("visible", !e.value); // Hide the button when readOnly: true
