React ColorBox Props

The value of this property will be passed to the accesskey attribute of the HTML element that underlies the UI component.

The UI component switches to the active state when users press down the primary mouse button. When this property is set to true, the CSS rules for the active state apply. You can change these rules to customize the component.

Use this property when you display the component on a platform whose guidelines include the active state change for UI components.

The property 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.

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

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

• Number
  The height in pixels.

• String
  A CSS-accepted measurement of height. For example, "55px", "20vh", "80%", "inherit".

• Function (deprecated since v21.2)
  Refer to the W0017 warning description for information on how you can migrate to viewport units.

To improve accessibility, use this property to specify aria-label for the component.

$(function(){
    $("#colorBoxContainer").dxColorBox({
        // ...
        inputAttr: {
            'aria-label': 'your-label',
        },
    });
});

<dx-color-box ...
    [inputAttr]="{ 'aria-label': 'your-label' }">
</dx-color-box>

<template>
    <DxColorBox
        :input-attr="inputAttr"
    />
</template>

<script>
import DxColorBox from 'devextreme-vue/color-box';

export default {
    components: {
        DxColorBox
    },
    data() {
        return {
            inputAttr: { 'aria-label': 'your-label' }
        }
    }
}
</script>

import ColorBox from 'devextreme-react/color-box';

const inputAttr = { 'aria-label': 'your-label' };

export default function App() {
    return (
        <ColorBox
            inputAttr={inputAttr}
        />
    );
}

You do not need to specify aria-label if you use label.

This property is a read-only flag. You can use it to check if the editor value changed.

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: [{

  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
              }
          }
      });
  });

When this property is set to true, the UI component 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:

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 property will be passed to the tabindex attribute of the HTML element that underlies the UI component.

• isValid

The following property values are possible:

• auto
  The tooltip with the message is displayed when the editor is in focus.
• always
  The tooltip with the message is not hidden when the editor loses focus.

If you set this property to auto, the component specifies the validation message position automatically.

The following example positions a validation message at the component's right:

$(function() {
    $("#colorBoxContainer").dxColorBox({
        // ...
        validationMessagePosition: 'right'
    }).dxValidator({
        validationRules: [{
            type: 'required',

The following table illustrates the validation status indicators:

validationStatus	Indicator
"pending"
"valid"
"invalid"

When you assign "invalid" to validationStatus, you can also use the validationErrors array to set an error message as shown below:

$(function() {
    const colorBox = $("#colorBoxContainer").dxColorBox({
        // ...
    }).dxColorBox("instance");

    function setInvalidStatus(message) {
        colorBox.option({
            validationStatus: "invalid",
            validationErrors: [{ message: message }]
        });
    }
});

<dx-color-box
    [validationStatus]="validationStatus"
    [validationErrors]="validationErrors">
</dx-color-box>

// ...
export class AppComponent {
    validationStatus: string = "valid";
    validationErrors: any;
    // ...
    setInvalidStatus(message) {
        this.validationStatus = "invalid";
        this.validationErrors = [{ message: message }];
    }
}

<template>
    <DxColorBox ...
        :validation-status="validationStatus"
        :validation-errors="validationErrors"
    />
</template>

<script>
    // ...
    export default {
        // ...
        data() {
            return {
                validationStatus: "valid",
                validationErrors: []
            }
        },
        methods: {
            setInvalidStatus(message) {
                this.validationStatus = "invalid";
                this.validationErrors = [{ message: message }];
            }
        }
    }
</script>

import React, { useState } from 'react';
// ...

function App() {
    const [validationStatus, setValidationStatus] = useState("valid");
    const [validationErrors, setValidationErrors] = useState([]);

    const setInvalidStatus = message => {
        setValidationStatus("invalid");
        setValidationErrors([{ message: message }]);
    }

    return (
        <ColorBox
            validationStatus={validationStatus}
            validationErrors={validationErrors}
        />
    ); 

};
export default App;
