Globalization in ASP.NET Core

4 Dec 202424 minutes to read

Globalization is the combination of adapting the control to various languages by parsing and formatting the date or numbers (Internationalization (L18N)), adding cultural-specific customizations and translating the text (Localization (L10N)). The American English (en-US) locale is set as default culture and USD is set as default currencyCode for all Syncfusion^® ASP.NET Core controls.

Loading Culture Data

It requires the following CLDR data to be loaded using loadCldr function for cultures other than en-US.

File Name	Path
ca-gregorian	cldr/main/en/ca-gregorian.json
timeZoneNames	cldr/main/en/timeZoneNames.json
numbers	cldr/main/en/numbers.json
numberingSystems	cldr/supplemental/numberingSystems.json
currencies	cldr/main/en/currencies.json

NOTE

For en, dependency files are already loaded in the library.

Installing CLDR Data and enable localization in schedule control

1.CLDR data is available as npm package. So, you can install it through the below command in the application root directory. Once the package is installed, you can find the culture specific JSON data under the location node_modules/cldr-data.

CMD

npm install cldr-data

2.Once the CLDR-Data installed create a folder cldr-data inside the wwwroot folder. Then create the folder directory like shown below in the structure inside the wwwroot folder.

• wwwroot/cldr-data/supplemental
• wwwroot/cldr-data/main

3.The files named as below are required to setup the specific culture to the Schedule control.

• numberingSystems.json
• ca-gregorian.json
• numbers.json
• timeZoneNames.json
• ca-islamic.json

4.The file named numberingSystems.json is available in the location node_modules/cldr-data/supplemental which is common for all the cultures. Now, you can move this file to the location wwwroot/cldr-data/supplemental.

5.The other required files mentioned above are available in the location node_modules/cldr-data/main/culture_code. In this location every culture has the culture files inside the folder named as its language culture code. For example if the German culture is loaded, then the German culture files could be found inside the location node_modules/cldr-data/main/fr-CH. Now, create a folder named fr-CH inside the location wwwroot/cldr-data/main and move the files inside it.

6.Now, use the below loadCultureFiles method to load the culture specific CLDR JSON data.

CSHTML

<script>
    loadCultureFiles('fr-CH');
    function loadCultureFiles(name) {
        var files = ['ca-gregorian.json', 'numberingSystems.json', 'numbers.json', 'timeZoneNames.json', 'ca-islamic.json'];
        var loader = ej.base.loadCldr;
        var loadCulture = function (prop) {
            var val, ajax;
            if (files[prop] === 'numberingSystems.json') {
                ajax = new ej.base.Ajax(location.origin + '/../cldr-data/supplemental/' + files[prop], 'GET', false);
            } else {
                ajax = new ej.base.Ajax(location.origin + '/../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>

7.The following code example lets you to set the culture to the Schedule control by using the locale property.

CSHTML

@using Syncfusion.EJ2
@{
    var dataManager = new DataManager()
    {
        Url = "https://ej2services.syncfusion.com/production/web-services/api/Schedule",
        Adaptor = "ODataV4Adaptor",
        CrossDomain = true
    };
}

<ejs-schedule id="schedule" width="100%" height="550" selectedDate="DateTime.Now" readonly="true" locale="fr-CH">
    <e-schedule-eventsettings dataSource="dataManager">
    </e-schedule-eventsettings>
</ejs-schedule>

<script>
    loadCultureFiles('fr-CH');
    function loadCultureFiles(name) {
        var files = ['ca-gregorian.json', 'numberingSystems.json', 'numbers.json', 'timeZoneNames.json', 'ca-islamic.json'];
        var loader = ej.base.loadCldr;
        var loadCulture = function (prop) {
            var val, ajax;
            if (files[prop] === 'numberingSystems.json') {
                ajax = new ej.base.Ajax(location.origin + '/../cldr-data/supplemental/' + files[prop], 'GET', false);
            } else {
                ajax = new ej.base.Ajax(location.origin + '/../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>

Changing Global Culture and Currency Code

To set the default culture and the currencyCode for all ASP.NET Core controls, you can use the methods setCulture for setting default locale and setCurrencyCode for setting the currencyCode in view page.

Setting Global Culture

CSHTML

<script>
    ej.base.setCulture('ar');
</script>

Setting Currency Code

CSHTML

<script>
    ej.base.setCurrencyCode('QAR');
</script>

NOTE

If global culture is not set, then en-US is set as default locale and USD is set as default currency code.

Manipulating Numbers

Supported Format String

Based on the NumberFormatOptions number formatting and parsing operations are processed. You need to specify some or all of the following properties mentioned in the below table.

No	Properties	Description
1	format	Denotes the format to be set. Possible values are 1. N - denotes numeric type. 2. C - denotes currency type. 3. P - denotes percentage type. E.g: formatNumber( 1234344 ,{format:'N4'}). > If no format is specified it takes numeric as default format type.
2	minimumFractionDigits	Indicates the minimum number of fraction digits . Possible values are 0 to 20.
3	maximumFractionDigits	Indicates the maximum number of fraction digits. Possible values are 0 to 20.
4	minimumSignificantDigits	Indicates the minimum number of significant digits. Possible values are 1 to 21. > If minimumSignificantDigits is given it is mandatory to give maximumSignificantDigits
5	maximumSignificantDigits	Indicates the maximum number of significant digits. . Possible values are 1 to 21. > If maximumSignificantDigits is given it is mandatory to give minimumSignificantDigits
6	useGrouping	Indicates whether to enable the group separator or not. By default grouping value will be true.
7	minimumIntegerDigits	Indicates the minimum number of the integer digits to be placed in the value. Possible values are 1 to 21.
8	currency	Indicates the currency code which needs to considered for the currency formatting.

NOTE

The minimumIntegerDigits, minimumFractionDigits and maximumFractionDigits are categorized as group one, minimumSignificantDigits and maximumSignificantDigits are categorized as group two. If group two properties are defined, then the group one properties will be ignored.

Custom number formatting and parsing

Custom number formatting and parsing are also be supported by specifying the pattern directly in the format property of NumberFormatOptions. Custom number format can be achieved by using one or more custom format specifiers listed in the below table.

Specifier	Description	Input	Format Output
0	Replaces the zero with the corresponding digit if one is present. Otherwise, zero appears in the result string.	instance.formatNumber(123,{format: ‘0000’ })	‘0123’
#	Replaces the “#” symbol with the corresponding digit if one is present; otherwise, no digit appears in the result string.	instance.formatNumber(1234,{format: ‘####’ })	‘1234’
.	Denotes the number of digits allowed after the decimal points if it’s not specified then no need to specify decimal point values.	instance.formatNumber(546321,{format: ‘###0.##0#’ })	‘546321.000’
%	Percent specifier denotes the percentage type format.	instance.formatNumber(1,{format: ‘0000 %’ })	‘0100 %’
$	Denotes the currency type format based on the global currency code specified.	instance.formatNumber(13,{format: ‘$ ###.00’ });	‘$ 13.00’
;	Denotes separate formats for positive, negative and zero values.	instance.formatNumber(-120,{format: ‘###.##;(###.00);-0’});	‘(120.00)’
‘String’ (single Quotes)	Denotes the characters enclosed within single Quote(‘) to be replaced in the resultant string.	instance.formatNumber(-123.44,{format: “####.## ‘@’”})	‘123.44 @’

NOTE

If custom format pattern is specified other NumberFormatOptions properties will not be considered.
