Angular DateBox Properties

An object defining configuration properties for the DateBox UI component.

See Also

acceptCustomValue

Specifies whether or not the UI component allows an end-user to enter a custom value.

Type:

Boolean

Default Value: true

accessKey

Specifies the shortcut key that sets focus on the UI component.

Type:

String

Default Value: undefined

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

activeStateEnabled

Specifies whether the UI component changes its state as a result of user interaction.

Type:

Boolean

Default Value: true

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.

adaptivityEnabled

Specifies whether or not adaptive UI component rendering is enabled on a small screen.

Type:

Boolean

Default Value: false

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 UI component to have a more compact representation. For this purpose, assign true to the adaptivityEnabled property. In the adaptive mode, the date box is displayed without the digital clock face.

applyButtonText

The text displayed on the Apply button.

Type:

String

Default Value: 'OK'

applyValueMode

Specifies the way an end-user applies the selected value.

Type:

String

Default Value: 'instantly'
Accepted Values: 'instantly' | 'useButtons'

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

  • "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".

buttons[]

Allows you to add custom buttons to the input text field.

Selector: dxi-button
Type:

Array<String | Object>

Default Value: undefined
Accepted Values: 'clear' | 'dropDown'

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

View Demo

calendarOptions

Configures the calendar's value picker. Applies only if the pickerType is "calendar".

Default Value: {}

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

NOTE
In Angular and Vue, the nested component that configures the calendarOptions property does not support event bindings and two-way property bindings.

cancelButtonText

The text displayed on the Cancel button.

Type:

String

Default Value: 'Cancel'

dateOutOfRangeMessage

Specifies the message displayed if the specified date is later than the max value or earlier than the min value.

Type:

String

Default Value: 'Value is out of range'

dateSerializationFormat

Specifies the date-time value serialization format. Use it only if you do not specify the value at design time.

Type:

String

Default Value: undefined

Without a value, the UI component cannot detect its format. In this case, specify the dateSerializationFormat property 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 property applies only if the forceIsoDateParsing field is set to true in the global configuration object.

NOTE
If you are going to change the value using the API, make sure that it has the same format that you specified in this property.

Specifies whether to render the drop-down field's content when it is displayed. If false, the content is rendered immediately.

disabled

Specifies whether the UI component responds to user interaction.

Type:

Alternatively, pass a function to disabledDates. This function should define the rules that determine whether the checked date is disabled. A separate set of rules should target every view individually.

    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() {
        $("#dateBoxContainer").dxDateBox({
            // ...
            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
                }
