jQuery ColorBox Options

See Also

• Configure a Widget: Angular | Vue | React | jQuery | AngularJS | Knockout | ASP.NET MVC 5 | ASP.NET Core

The value of this option will be passed to the accesskey attribute of the HTML element that underlies the widget.

This option is used when the widget is displayed on a platform whose guidelines include the active state change for widgets.

The option accepts the following values.

• "useButtons"
  Enables an end-user to apply the selected value or cancel the selection using the Apply and Cancel buttons respectively.

• "instantly"
  Applies the selected value immediately after a user clicks the required value in the drop-down menu. To cancel the selection, click outside the drop-down menu.

Use the EditorApplyValueMode enum to specify this option when the widget is used as an ASP.NET MVC 5 Control or a DevExtreme-Based ASP.NET Core Control. This enum accepts the following values: Instantly and UseButtons.

Built-in buttons should also be declared in this array. You can find an example in the following demo:

This option accepts a value of one of the following types:

• Number
  The height in pixels.

• String
  A CSS-accepted measurement of height. For example, "55px", "80%", "inherit".

• Function
  A function returning either of the above. For example:

  JavaScript

  height: function() {
      return window.innerHeight / 1.5;
  }

Specify this option if the widget lies within an HTML form that will be submitted.

If you configure the widget as an ASP.NET MVC 5 Control or a DevExtreme-Based ASP.NET Core Control, use this option to bind the widget to a model property. If this model property contains Data Annotation validation attributes, you get the client-side validation enabled by default.

When this option 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 option to false:

  jQuery

  index.js

  $(function() {
      $("#colorBoxContainer").dxColorBox({
          // ...
          buttons: [{
              name: "myCustomButton",
              location: "after",
              options: {
                  onClick: function(e) {
                      // ...
                  },
                  disabled: false
              }
          }]
      });
  });

              </ColorBox>
          );
      }

  export default App;

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

  Angular

      (onOptionChanged)="changeButtonState">

          ...
      ></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';

              }

  </script>

  React

  App.js

  import 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;

When this option is set to true, the widget text flows from right to left, and the layout of elements is reversed. To switch the entire application/site to the right-to-left representation, assign true to the rtlEnabled field of the object passed to the DevExpress.config(config) method.

DevExpress.config({
    rtlEnabled: true
});

The following styles are available:

Use the EditorStylingMode enum to specify this option when the widget is used as an ASP.NET MVC 5 Control or a DevExtreme-Based ASP.NET Core Control. This enum accepts the following values: Outlined, Underlined, and Filled.

You can also use the global editorStylingMode setting to specify how the text fields of all editors in your application are styled.

The value of this option will be passed to the tabindex attribute of the HTML element that underlies the widget.

  The width in pixels.

• String
  A CSS-accepted measurement of width. For example, "55px", "80%", "auto", "inherit".
