Localization

The article elaborates on how to localize the messages displayed by the Angular Report Viewer.

  1. To localize the report viewer, create a new TypeScript file stringResources.ts :

    export class StringResources {
        static english = {
            loadingReport: 'Loading...',
            // override other string resources here
        }
        static japanese = {
            loadingReport: 'ちょっと、まってください...',
            // override other string resources here
        }
        // override string resources for other cultures here
    }
    
    The file can contain all or only part of the string resources which would be localized. For a full list of the report viewer string resources which could be localized please refer to HTML5 Report Viewer Localization.
  2. Import the new file in the component where the viewer is used:

    import { StringResources } from './stringResources';
    
  3. Implement AfterViewInit and extend the viewer object with the string resources for the desired culture:

    import { AfterViewInit, Component, ViewChild } from '@angular/core';
    import { TelerikReportViewerComponent } from '@progress/telerik-angular-report-viewer';
    import { StringResources } from './stringResources';
    ...
    export class AppComponent implements AfterViewInit {
      @ViewChild('viewer1') viewer: TelerikReportViewerComponent;
      ngAfterViewInit(): void {
        const language = navigator.language;
        let resources = StringResources.english; // default
        if(language === 'ja-JP'){
          resources = StringResources.japanese;
        }
        this.viewer.viewerObject.stringResources = Object.assign(this.viewer.viewerObject.stringResources, resources);
      }
    }
