Angular DateBox Properties

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.

While displaying DateBox in your app, you may want to use different layouts for different screen sizes. While desktop monitors provide enough space, mobile screens do not. In this case, you can enable the widget to have a more compact representation. For this purpose, assign true to the adaptivityEnabled option. In the adaptive mode, the date box is displayed without the digital clock face.

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. When the pickerType is 'calendar', choosing this mode activates the showTodayButton option.

• "instantly"
  Applies the selected value immediately after a user clicks the required value in the drop-down menu. This mode cannot be used if the pickerType is "rollers" or the type is "datetime".

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:

You can specify most of the Calendar options in this object except those listed below. These options are overridden by their DateBox counterparts.

• dateSerializationFormat
• disabledDates
• max
• min
• onValueChanged
• tabIndex
• value

Without a value, the widget cannot detect its format. In this case, specify the dateSerializationFormat option that supports the following formats:

• "yyyy-MM-dd" - a local date

• "yyyy-MM-ddTHH:mm:ss" - local date and time

• "yyyy-MM-ddTHH:mm:ssZ" - the UTC date and time

• "yyyy-MM-ddTHH:mm:ssx" - date and time with a timezone

This option applies only if the forceIsoDateParsing field is set to true in the global configuration object.

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

• Specify the Value Range

If the number of entered characters reaches the value assigned to this option, the widget does not allow you to enter any more characters.

The zoom level ascends from "month" to "century" ("month"->"year"->"decade"->"century").

The option makes sense only if the pickerType option is set to "calendar".

Use the CalendarZoomLevel 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: Month, Year, Decade, and Century.

The zoom level ascends from "month" to "century" ("month"->"year"->"decade"->"century").

The option makes sense only if the pickerType option is set to "calendar".

Use the CalendarZoomLevel 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: Month, Year, Decade, and Century.

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.

This option accepts the following values.

• "native"
  The picker type depends on the current platform or web browser.

• "calendar"
  The date box uses the Calendar widget to pick data. This value applies only when the type option is set to "date" or "datetime".

• "rollers"
  The widget uses rollers to pick the date and time.

• "list"
  The widget uses the list of time values to pick the time. This value applies only when the type option is set to "time".

Use the DateBoxPickerType 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: Native, Calendar, Rollers, and List.

This text is also shown in the date picker's title in the following cases:

• If the pickerType is "rollers".
• If the application runs on an iOS device and the pickerType is not "native".

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() {
      $("#dateBoxContainer").dxDateBox({
          // ...
          buttons: [{

          // ...
          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
              }
          }
      });
  });

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.

You can assign the following values to this option:

• date - the widget displays only the date;
• time - the widget displays only the time;
• datetime - the widget displays both the date and time.

Use the DateBoxType 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: Date, DateTime, and Time.

The following option 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.

Use the ValidationMessageMode 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: Auto and Always.

The following table illustrates the validation status indicators:

validationStatus	Indicator
"pending"
"valid"
"invalid"

You can specify the current widget value using any of the following formats.

• Date
  Specifies the date directly.

• Number
  Specifies the date using a timestamp (total milliseconds since 1970/01/01).

• String
  Specifies the date using a string value. The widget supports the following formats of a date string.

  • "yyyy-MM-dd" (for example, "2017-03-06")
  • "yyyy-MM-ddTHH:mm:ss" (for example, "2017-03-27T16:54:48")
  • "yyyy-MM-ddTHH:mm:ssZ" (for example, "2017-03-27T13:55:41Z")
  • "yyyy-MM-ddTHH:mm:ssx" (for example, "20170327T16:54:10+03")

If the widget value is changed by an end-user, the new value is saved in the same format as the initial value.

This option accepts a single event name or several names separated by spaces.

The recommended events are "keyup", "blur", "change", and "focusout", but you can use other events as well.

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

• Number
  The width in pixels.

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

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

  JavaScript

  width: function() {
      return window.innerWidth / 1.5;
