Hello FabioNicc,

we prepared a localization demo for you. Here is how you can set the messages property:

grid.messages = {
        'en': {
            'columnMenuItemSortAsc': 'Sort {{mode}}',
            'columnMenuItemSortDesc': 'Sort {{mode}}', //Sort A → Z
            'columnMenuItemRemoveSort': 'Remove Sort',
            'currencySymbol': '£',
        },
        'de': {
            'columnMenuItemSortAsc': 'Sortieren {{mode}}',
            'columnMenuItemSortDesc': 'Sortieren {{mode}}',
            'columnMenuItemRemoveSort': 'Sortierung entfernen',
            'currencySymbol': '€',
        },
    };

and by switching the “locale” property, you can change the language code:

grid.locale = 'de';

grid.locale = 'en';

We also implemented two format functions. The first one translates the month of the date, and the second one switch the currency symbol according to the selected language.

Here is the index.htm file for the demo:

Here is the index.js file:

function setLocalizationCurrency(grid, currency) {
    return grid.localize('currencySymbol') + currency.toFixed(2);
}

function setLocalizationDate(grid, date) {
    let dateLocale = 'de-DE';
    if (grid.locale === 'en') {
        dateLocale = 'en-GB';
    }

    return date.toLocaleString(dateLocale, { timeZone: 'UTC', weekday: 'long', year: 'numeric', month: 'long', day: 'numeric' });
}

let localizationColumnLabelsDe = [
    {
        label: 'Vorname' //First Name
    },
    {
        label: 'Familienname' //Last Name
    },
    {

        label: 'Gesamt' //Total
    },
];
let localizationColumnLabelsEn = [
    {
        label: 'First Name'
    },
    {
        label: 'Last Name'
    },
    {
        label: 'Date'
    },
    {
        label: 'Total'
    },
];

let defaultLocalizationColumnLabels = localizationColumnLabelsDe;

window.onload = function () {
    const radioButtons = document.querySelectorAll('smart-radio-button.language');
    const grid = document.getElementById('grid');
    
    grid.locale = 'de'; //Settings default locale
    grid.messages = {
        'en': {
            'columnMenuItemSortAsc': 'Sort {{mode}}',

        'de': {
            'columnMenuItemSortAsc': 'Sortieren {{mode}}',
            'columnMenuItemSortDesc': 'Sortieren {{mode}}', 
            'columnMenuItemRemoveSort': 'Sortierung entfernen',
            'currencySymbol': '€',
        },
    };

    for (let i = 0; i < radioButtons.length; i++) {
        const radioButton = radioButtons[i];

        radioButton.addEventListener('change', function (event) {
            let localizationColumnLabels = defaultLocalizationColumnLabels;

            if (event.detail.value) {
                if (this.id === 'en') {
                    localizationColumnLabels = localizationColumnLabelsEn;
                }

                //Update column labels
                for (let i = 0; i < localizationColumnLabels.length; i++) {
                    grid.columns[i].label = localizationColumnLabels[i].label;
                }
                grid.locale = this.id;
            }
        });
    }
}
