Globalization in ASP.NET MVC TimePicker control

Globalization is the combination of internalization and localization. You can adapt the component to various languages by parsing and formatting the date or number internationalization and also add culture specific customization and translation to the text localization.

By default, TimePicker time format and meridian names are specific to the American English culture. It utilizes the Essential JavaScript 2 Internationalization package to parse and format the date object based on the culture by using the official UNICODE CLDR JSON data. It provides the loadCldr method to load culture specific CLDR JSON data.

  • Set the culture by using the locale property.

To go with the different culture other than English, follow the below steps.

  • Install the CLDR-Data package by using the below command (it installs the CLDR JSON data). To know more about CLDR-Data refer the CLDR-Data link.
npm install cldr-data --save

Once the package installed, you can find the culture specific JSON data under the location \node_modules\cldr-data.

In ASP.NET MVC refer the culture files directly from \node_modules\cldr-data location.

    function loadCultureFiles(name) {
        var files = ['ca-gregorian.json', 'numbers.json', 'timeZoneNames.json'];
        var loader = ej.base.loadCldr;
        var loadCulture = function (prop) {
            var val, ajax;
            ajax = new ej.base.Ajax(location.origin + location.pathname + '/../../node_modules/cldr-data/main/' + name + '/' + files[prop], 'GET', false);
            ajax.onSuccess = function (value) {
                val = value;
            };
            ajax.send();
            loader(JSON.parse(val));
        };
        for (var prop = 0; prop < files.length; prop++) {
            loadCulture(prop);
        }
    }
  • Before changing to a culture other than English, ensure that locale text for the concerned culture is loaded through load method of L10n class.
     var L10n = ej.base.L10n;
        L10n.load({
            'de': {
                'timepicker': { placeholder: 'Wählen Sie Zeit' }
            }
        });

The following example demonstrates the TimePicker in German culture.

razor
@Html.EJS().TimePicker("timepicker").Placeholder("Select Time").Render()

<script>
    document.addEventListener('DOMContentLoaded', function () {
        timepicker = document.getElementById('timepicker').ej2_instances[0];
        var L10n = ej.base.L10n;
        L10n.load({
            'de': {
                'timepicker': { placeholder: 'Wählen Sie Zeit' }
            }
        });
        loadCultureFiles("de");
        timepicker.locale = 'de';
    });


    function loadCultureFiles(name) {
        var files = ['ca-gregorian.json', 'numbers.json', 'timeZoneNames.json'];
        var loader = ej.base.loadCldr;
        var loadCulture = function (prop) {
            var val, ajax;
            if (name === 'ar' && prop === files.length - 1) {
                ajax = new ej.base.Ajax(location.origin + location.pathname + '/../../node_modules/cldr-data/supplemental/' + files[prop], 'GET', false);
            } else {
                ajax = new ej.base.Ajax(location.origin + location.pathname + '/../../node_modules/cldr-data/main/' + name + '/' + files[prop], 'GET', false);
            }
            ajax.onSuccess = function (value) {
                val = value;
            };
            ajax.send();
            loader(JSON.parse(val));
        };
        for (var prop = 0; prop < files.length; prop++) {
            loadCulture(prop);
        }
    }

</script>

Right-To-Left

The TimePicker supports RTL (right-to-left) functionality for languages like Arabic and Hebrew to displays the text in the right-to-left direction. Use enableRtl property to set the RTL direction.

The following code example demonstrates the TimePicker component in Arabic culture. It also explains how to set localized text to the placeholder using L10n.load method.

The following example demonstrates TimePicker in Arabic culture with right-to-left direction.

razor
@Html.EJS().TimePicker("timepicker").EnableRtl(true).Placeholder("Select a time").Render()

<script>
    document.addEventListener('DOMContentLoaded', function () {
        timepicker = document.getElementById('timepicker').ej2_instances[0];
        var L10n = ej.base.L10n;
        L10n.load({
            'ar': {
                'timepicker': { placeholder: 'حدد الوقت' }
            }
        });
        loadCultureFiles("ar");
        timepicker.locale = "ar";
    });


    function loadCultureFiles(name) {
        var files = ['ca-gregorian.json', 'numbers.json', 'timeZoneNames.json'];
        if (name === 'ar') {
            files.push('numberingSystems.json');
        }
        var loader = ej.base.loadCldr;
        var loadCulture = function (prop) {
            var val, ajax;
            if (name === 'ar' && prop === files.length - 1) {
                ajax = new ej.base.Ajax(location.origin + location.pathname + '/../../node_modules/cldr-data/supplemental/' + files[prop], 'GET', false);
            } else {
                ajax = new ej.base.Ajax(location.origin + location.pathname + '/../../node_modules/cldr-data/main/' + name + '/' + files[prop], 'GET', false);
            }
            ajax.onSuccess = function (value) {
                val = value;
            };
            ajax.send();
            loader(JSON.parse(val));
        };
        for (var prop = 0; prop < files.length; prop++) {
            loadCulture(prop);
        }
    }

</script>
