• Configure a UI Component: Angular | Vue | React | jQuery | AngularJS | Knockout

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. See the following GitHub repository for an example of this type of platform: MUI.

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", "80%", "inherit".

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

  JavaScript

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

The following example shows how to subscribe to component property changes:

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",

  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
              }
          }
      });
  });

              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.

See Also

• 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.

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 }]
        });
    }
});
