Component Sample

Class sample

You need to add a translation key via the property nameKey to each column definition, for example: nameKey: 'TITLE'

Translation Files

If you want to manually re-create the translation in your own files, the list of translations that you will need are displayed in the asset i18n translation folder (from that file, you need all translations shown before the translation 'BILLING', the next few ones are for the demo page only). If you need more information on how to import translations, please review the other docs page.

Note

For the Select Filter, you will use labelKey instead of label. Anytime a translation key will come in play, we will add the word key to the end (hence nameKey, labelKey, more to come...)

import { Component, OnInit, Injectable } from '@angular/core';
import { Column, Editors, Formatter, Formatters, GridExtraService, GridExtraUtils, GridOption, OnEventArgs, ResizerService } from 'angular-slickgrid';
import { TranslateService } from '@ngx-translate/core';

@Component({
  templateUrl: './grid-localization.component.html'
})
@Injectable()
export class Example implements OnInit {
  gridOptions: GridOption;
  columnDefinitions: Column[];
  dataset: any[];

  constructor(private translate: TranslateService) {
    // define the grid options & columns and then create the grid itself
    this.defineGrid();
  }

  // Define grid Options and Columns
  // provide a nameKey for each column and enableTranslate to True in GridOption
  defineGrid() {
    this.columnDefinitions = [
      { id: 'title', name: 'Title', field: 'title', nameKey: 'TITLE', formatter: this.taskTranslateFormatter, sortable: true, minWidth: 100 },
      { id: 'duration', name: 'Duration (days)', field: 'duration', nameKey: 'DURATION', sortable: true, minWidth: 100 },
      { id: 'start', name: 'Start', field: 'start', nameKey: 'START', formatter: Formatters.dateIso, minWidth: 100 },
      { id: 'finish', name: 'Finish', field: 'finish', nameKey: 'FINISH', formatter: Formatters.dateIso, minWidth: 100 },
      { id: 'completed', name: 'Completed', field: 'completed', nameKey: 'COMPLETED', formatter: Formatters.translate, sortable: true, minWidth: 100 }
      // OR via your own custom translate formatter
      // { id: 'completed', name: 'Completed', field: 'completed', nameKey: 'COMPLETED', formatter: translateFormatter, sortable: true, minWidth: 100 }
    ];
    this.gridOptions = {
      autoResize: {
        containerId: 'demo-container',
        sidePadding: 15
      },
      enableAutoResize: true,
      enableTranslate: true,
      i18n: this.translate
    };
  }
}

  // create a custom translate Formatter
  taskTranslateFormatter: Formatter = (row, cell, value, columnDef, dataContext) => {
    return this.translate('TASK_X', { x: value });
  }

Custom Formatter (cell values)

You can define your own custom Formatter by providing the i18n Service into the Formatter and using the .tr() function to translate the cell value.

taskTranslateFormatter: Formatter = (row, cell, value, columnDef, dataContext) => {
    return this.translate.instant('TASK_X', { x: value });
}

Filtering with Translated cell value (translateFormatter)

Since the cell value is to be translated, the regular filtering might behave differently than excepted (it will filter against a translation key instead of filtering against the formatted output which is what we want). If you want to filter against the formatted output (translateFormatter or even a custom formatter), you need to fill in the i18n property in the Grid Options and set useFormatterOuputToFilter to True, for more info please see Wiki - input filter with localization

Using Angular-Slickgrid Formatters.Translate

Instead of defining a custom formatter over and over, you could also use the built-in Angular-Slickgrid Formatters.translate. However for the formatter to work, you need to provide the ngx-translate Service instance, to the Grid Options property i18n, as shown below.

this.columnDefinitions = [
  {
    id: 'title',
    name: 'Title',
    field: 'title',
    nameKey: 'TITLE',
    formatter: Formatters.translate
  }
];

this.gridOptions = {
  enableTranslate: true,
  i18n: this.translate  // provide the `ngx-translate instance through the params.i18n property
}
