The mask pattern is defined based on the provided date format to the component. If the format is not specified, the mask pattern is formed based on the default format of the current culture.

Keys Actions

Configure Mask Placeholder

You can change mask placeholder value through property maskPlaceholder. By default , it takes the full name of date and time co-ordinates such as day, month, year, hour etc.

While changing to a culture other than English, ensure that locale text for the concerned culture is loaded through load method of L10n class for mask placeholder values like below.

//Load the L10n from ej2-base
import { L10n } from '@syncfusion/ej2-base';

//load the locale object to set the localized mask placeholder value
L10n.load({
'de': {
    'datetimepicker': { day: 'Tag' , month: 'Monat', year: 'Jahr', hour: 'Stunde' ,minute: 'Minute', second:'Sekunden' }
}
});

The following example demonstrates default and customized mask placeholder value.
