Angular
<dx-color-box ... (onOptionChanged)="handlePropertyChange($event)"> </dx-color-box>

readOnly
When this property is set to true, the following applies:
- The editor's value cannot be changed using the UI.
- Built-in action buttons are invisible.
Custom action buttons are visible but disabled. If a button should not be disabled, set its disabled property to false:
jQuery
index.js$(function() { $("#colorBoxContainer").dxColorBox({ // ... buttons: [{ name: "myCustomButton", location: "after", options: { onClick: function(e) { // ... }, disabled: false } }] }); });
Angular
app.component.htmlapp.component.tsapp.module.ts<dx-color-box ... > <dxi-button name="myCustomButton" location="after" [options]="myCustomButtonConfig"> </dxi-button> </dx-color-box>
import { Component } from '@angular/core'; @Component({ selector: 'app-root', templateUrl: './app.component.html', styleUrls: ['./app.component.css'] }) export class AppComponent { myCustomButtonConfig = { onClick: (e) => { // ... }, disabled: false }; }
import { BrowserModule } from '@angular/platform-browser'; import { NgModule } from '@angular/core'; import { AppComponent } from './app.component'; import { DxColorBoxModule } from 'devextreme-angular'; @NgModule({ declarations: [ AppComponent ], imports: [ BrowserModule, DxColorBoxModule ], providers: [ ], bootstrap: [AppComponent] }) export class AppModule { }
Vue
App.vue<template> <DxColorBox ... > <DxColorBoxButton name="myCustomButton" location="after" :options="myCustomButtonConfig" /> </DxColorBox> </template> <script> import 'devextreme/dist/css/dx.common.css'; import 'devextreme/dist/css/dx.light.css'; import DxColorBox, { DxButton as DxColorBoxButton } from 'devextreme-vue/color-box'; export default { components: { DxColorBox, DxColorBoxButton }, data() { return { myCustomButtonConfig: { onClick: (e) => { // ... }, disabled: false } } } } </script>
React
App.jsimport React from 'react'; import 'devextreme/dist/css/dx.common.css'; import 'devextreme/dist/css/dx.light.css'; import ColorBox, { Button as ColorBoxButton } from 'devextreme-react/color-box'; class App extends React.Component { myCustomButtonConfig = { onClick: (e) => { // ... }, disabled: false }; render() { return ( <ColorBox> <ColorBoxButton name="myCustomButton" location="after" options={this.myCustomButtonConfig} /> </ColorBox> ); } } export default App;
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 } } }); });
Angular
app.component.htmlapp.component.tsapp.module.ts<dx-color-box ... (onOptionChanged)="changeButtonState"> <dxi-button name="myCustomButton" ... ></dxi-button> </dx-color-box>
import { Component } from '@angular/core'; @Component({ selector: 'app-root', templateUrl: './app.component.html', styleUrls: ['./app.component.css'] }) export class AppComponent { changeButtonState(e) { if(e.name == 'readOnly') { let myButton = e.component.getButton('myCustomButton'); myButton.option('visible', !e.value); // Hide the button when readOnly: true } } }
import { BrowserModule } from '@angular/platform-browser'; import { NgModule } from '@angular/core'; import { AppComponent } from './app.component'; import { DxColorBoxModule } from 'devextreme-angular'; @NgModule({ declarations: [ AppComponent ], imports: [ BrowserModule, DxColorBoxModule ], providers: [ ], bootstrap: [AppComponent] }) export class AppModule { }
Vue
App.vue<template> <DxColorBox ... @option-changed="changeButtonState"> <DxColorBoxButton name="myCustomButton" ... /> </DxColorBox> </template> <script> import 'devextreme/dist/css/dx.common.css'; import 'devextreme/dist/css/dx.light.css'; import DxColorBox, { DxButton as DxColorBoxButton } from 'devextreme-vue/color-box'; export default { components: { DxColorBox, DxColorBoxButton }, data() { return { // ... } }, methods: { changeButtonState(e) { if(e.name == 'readOnly') { let myButton = e.component.getButton('myCustomButton'); myButton.option('visible', !e.value); // Hide the button when readOnly: true } } } } </script>
React
App.jsimport React from 'react'; import 'devextreme/dist/css/dx.common.css'; import 'devextreme/dist/css/dx.light.css'; import ColorBox, { Button as ColorBoxButton } from 'devextreme-react/color-box'; class App extends React.Component { changeButtonState(e) { if(e.name == 'readOnly') { let myButton = e.component.getButton('myCustomButton'); myButton.option('visible', !e.value); // Hide the button when readOnly: true } } render() { return ( <ColorBox ... onOptionChanged={this.changeButtonState}> <ColorBoxButton name="myCustomButton" ... /> </ColorBox> ); } } export default App;
rtlEnabled
