Configuration

An object defining configuration options for the DateBox widget.

acceptCustomValue

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

Type: Boolean
Default Value: true

accessKey

Specifies a shortcut key that sets focus on the widget element.

In the adaptive mode, the date box is displayed without the digital clock face.

Type: String
Default Value: 'Value must be a date or time'

isValid

Specifies whether the editor's value is valid.

Type: Boolean
Default Value: true

In Knockout approach, you may need to use an editor to inform end users that an error occurred during the validation of a ViewModel field. In this instance, set the editor's isValid option to the isValid property value of the dxValidator that validated the ViewModel's field. In addition, set the editor's validationError option to the validationError property value of the dxValidator object.

In the code below, the login specified by an end user is validated on the level of the ViewModel. If validation of the login value fails, a validation message is displayed on the Login editor.

HTML
<div data-bind="dxTextBox: {
    value: login,
    isValid: login.dxValidator.isValid,
    validationError: login.dxValidator.validationError,
    placeholder: 'Login'
}"></div>
JavaScript
var viewModel = {
    login: ko.observable("").extend({
        dxValidator: {
            validationRules: [{
                type: 'required',
                message: 'Login is required'
            }]
        }
    }),
    //...
}
NOTE
The editor's isValid option, as well as the validationError option, should also be specified when using a custom validation engine. In this instance, the validation result will be displayed for the editor by the means of the DevExtreme Validation UI.

In Knockout approach, you may need to use an editor to inform end users that an error occurred during the validation of a ViewModel field. In this instance, set the editor's isValid option to the isValid property value of the dxValidator that validated the ViewModel's field. In addition, set the editor's validationError option to the validationError property value of the dxValidator object.

In code, the login specified by an end user is validated on the level of the ViewModel. If validation of the login value fails, a validation message is displayed on the Login editor.

HTML
<div data-bind="dxTextBox: {
    value: login,
    isValid: login.dxValidator.isValid,
    validationError: login.dxValidator.validationError,
    placeholder: 'Login'

            validationRules: [{ type: 'required', message: 'Login is required' }]
        }
    }),
    //...
}

The editor's validationError option, as well as the isValid option, should also be specified when using a custom validation engine. In this instance, the validation result will be displayed for the editor by means of the DevExtreme Validation UI. For details, refer to the Use Custom Validation Engine topic.
