Angular DateBox Properties

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

This property is used when the UI component is displayed on a platform whose guidelines include the active state change for UI components.

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.

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".

Use the EditorApplyValueMode enum to specify this property when the UI component 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 properties in this object except those listed below. These properties are overridden by their DateBox counterparts.

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

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.

This property accepts an array of dates:

$(function() {
    $("#dateBoxContainer").dxDateBox({
        // ...
        disabledDates: [ 
            new Date("07/1/2017"),  
            new Date("07/2/2017"), 
            new Date("07/3/2017") 
        ]
    });
});

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.

$(function() {

            return isWeekend || isMarch;

• Number
  The height in pixels.

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

• Specify the Value Range

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

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

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

Use the CalendarZoomLevel enum to specify this property when the UI component 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 property makes sense only if the pickerType property is set to "calendar".

Use the CalendarZoomLevel enum to specify this property when the UI component 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 property if the UI component lies within an HTML form that will be submitted.

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

This property accepts the following values.

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

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

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

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

Use the DateBoxPickerType enum to specify this property when the UI component 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 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() {
      $("#dateBoxContainer").dxDateBox({
          // ...
          buttons: [{
              name: "myCustomButton",
              location: "after",
              options: {
                  onClick: function(e) {
                      // ...
                  },

  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
              }
          }
      });
  });

DevExpress.config({
    rtlEnabled: true
});
